To give a sense of timing, you can see in this chart the samples detected by Cyren per day during the month of January for the first Emotet variant, Downldr.IE.gen, which appeared in greater volume. What is Emotet Malware? Emotet malware is a type of trojan primarily spread through email spam that persuades users to click on a malicious link or file by using persuasive language in the copy of the email. The malware then enters the users system with the goal of stealing banking and financial credentials. A Brief History of Emotet Emotet was first identified in 2014 and was used with the intention of stealing bank account information. By 2015, a new version of Emotet appeared with new modifications to keep malware under the detection radar and target Swiss banks. Fast forward a few years, and in 2018 Emotet now had the ability to install other ransomware and trojans to infected machines. After going quiet for a short period, 2019 saw Emotet come back with a new campaign targeting German, Polish, Italian, and English victims with malicious emails containing subject lines like Overdue Invoice and Payment Remittance in order to get into their network and infect their system. Today, Emotet malware continues to pose a huge threat to the security of email recipients. How Does Emotet Spread? The most common way Emotet spreads is through malspam where Emotet hijacks a users contact list and sends itself to friends, family, and coworkers. Your contact list receives an email that they feel inclined to open since its coming from someone they know, they click on a malicious URL, and Emotet downloads infected files. Additionally, Emotet can spread using a list of common passwords to compromise someones system using bruteforce or password spraying attacks. Who Does Emotet Target? Unfortunately, no one is immune to an attack from Emotet. Since it first hit the scene in 2014, Emotet has targeted individuals, companies, and government entities throughout the United States and European Union. Breaking Down the Emotet Malware Variants Variants of the Emotet malware are continuing to present themselves. Here is a breakdown of the variants we know so far and how to detect them. 1st Emotet Variant Eldorado Malware This first variant Cyren detects as PP97MDownldr.IE.gen!Eldorado. It appeared in very small volumes during January, suggesting it was just being initially tested. This is what the email attachment looks like that delivers Emotet onto the users system when the macro runs The macro retrieves the text in the Form properties, in this case the Tag. A large amount of text, 10660 bytes, is retrieved. They get the malicious code from the string content, a combination of reverse, split,  join methods were used. The outcome is a PowerShell command line with its script encoded. Decoding the script reveals a downloader code.

Here is an analysis of a sample that uses WScript Shell to execute the downloaded payload. The attachment to this variant also presents a Word document with the same text as the first sample. But here, opening the file and enabling the macro, we can see that there is a comment in the actual file. This comment is the malicious script retrieved by the macro. The toP argument is the random filename which has a .jse extension, where it will copy the contents. The file is dropped in the APPDATA folder and executed. The dropped .jse file is obfuscated. It also has anti -debugging and anti-console-logging features. This sample is similar to variants spotted last year. The b function is responsible for decrypting the strings. Here are some of the strings it will try to decrypt. It includes some of the URLs it will use to download the payload. This part of the function hooks into the console logging. It monitors for the different types of console logs and returns a call to an empty function. Anti-debugging Emotet malware For any analysts that attempt to debug the script using the developer tools on browsers like Chrome, be aware the script has a function to make it a little bit difficult to analyze. Here we can see that it tries to make a call to the gG function. Once initialized, the value of aS will be the function h9. Below is an excerpt of the code for the gG function that shows a scenario in what could happen if debugging the script in chrome. The h9 function is part of it. We remove some parts of the code just to show the scenario when h90 is called when debugging in chrome. It will execute an anonymous function to call the debugger. And create a loop with h9ha . So it will loop calling the debugger.

    "content": "### Comprehensive Analysis of Emotet Malware Content\n\n#### 1. Key Security Features and Their Benefits to Users\n\nThe content highlights several key security features that are crucial for protecting against Emotet malware:\n\n- **Sandbox Analysis**: This feature allows for the safe execution of email attachments in a controlled environment, preventing potential malware from infecting the actual system. It benefits users by providing an additional layer of security against unknown threats.\n\n- **Multi-Factor Authentication (MFA)**: MFA adds an extra layer of security by requiring multiple forms of verification, making it harder for attackers to gain unauthorized access. This benefits users by protecting their accounts even if passwords are compromised.\n\n- **Antivirus Programs**: These programs detect and remove malware, including variants of Emotet. Regular updates ensure protection against the latest threats.\n\n- **Phishing Protection Software**: Such software, like Cyren, helps detect and block phishing attempts, benefiting users by reducing the risk of falling victim to email-based attacks.\n\n#### 2. Compliance Certifications and Regulatory Adherence\n\nThe provided content does not mention specific compliance certifications or regulatory adherence. However, protection against Emotet aligns with general security best practices, which often form the basis of various regulatory requirements. Organizations are encouraged to ensure their security measures comply with relevant standards such as GDPR or NIST.\n\n#### 3. User-Focused Security Recommendations\n\nThe content provides several user-focused recommendations to protect against Emotet:\n\n- **Caution with Email Attachments**: Users should be vigilant and avoid opening suspicious emails, even from known senders, as Emotet often hijacks contact lists.\n\n- **Strong Passwords**: Using hard-to-guess passwords and avoiding common ones can prevent brute-force attacks. Regular password changes are also advisable.\n\n- **Phishing Protection Software**: Utilizing software that detects phishing emails can significantly reduce the risk of infection.\n\n- **Macro-Enabled Documents**: Users should exercise caution when enabling macros in documents, as they can execute malicious code.\n\n- **Network Segmentation**: Segmenting networks can limit the spread of malware, containing breaches more effectively.\n\n#### 4. Technical Security Implementation Details\n\nEmotet employs several technical tactics:\n\n- **WScript Shell Execution**: Malicious scripts execute payloads using WScript Shell, facilitating the downloading of additional malware components.\n\n- **Macro-Enabled Documents**: Malicious macros in Word documents retrieve and execute code, often through obfuscation and anti-debugging techniques.\n\n- **Obfuscation and Anti-Debugging**: Scripts obfuscate code to avoid detection and use functions to hinder analysis, making them harder to debug.\n\n- **Downloader Variants**: Different variants like Downldr.IE.gen and Powload.C.gen use distinct methods to infect systems, highlighting the need for robust detection mechanisms.\n\n#### 5. Data Protection Measures\n\nTo protect against Emotet, the following data protection strategies are essential:\n\n- **Network Segmentation**: Isolates infected areas, preventing lateral movement of malware.\n\n- **Regular Backups**: Ensures data recovery in case of ransomware attacks.\n\n- **Encryption**: Protects data from unauthorized access, even if compromised.\n\n- **Employee Education**: Training users to recognize and avoid phishing attempts can prevent initial infection.\n\n#### 6. Best Practices for End Users\n\nEnd users should adopt these best practices:\n\n- **Stay Informed**: Keep up-to-date with the latest threats and security measures.\n\n- **Regular Updates**: Ensure all software and systems are updated to protect against vulnerabilities.\n\n- **Suspicious Email Handling**: Verify the authenticity of emails before interacting with links or attachments.\n\n- **Security Software**: Install and regularly update antivirus and anti-malware tools.\n\n- **Password Management**: Use strong, unique passwords and consider a password manager.\n\nBy implementing these measures, users can significantly enhance their security posture against Emotet and similar threats.",
