We previously reported our detection of key changes in Lockys methods on June 27  new sandbox evasion techniques , July 4  new downloading technique , July 14  attachment format change , and most recently July 21  embedded in JavaScript   the criminal syndicate behind Locky is evidently quite busy, and quite resourceful. The email being sent in this latest wave, as often before, uses business finance-related topics to lure users into opening its attachment, which is ZIP-archived JavaScript. Comparing this variant to the earlier variants, it has added another layer of obfuscation which decrypts and executes the real Locky downloader script. A quick de-obfuscation shows a similar structure to the previous Locky downloader scripts. The download behavior is similar to that seen before, as the files downloaded from the URLs inserted in the script are decrypted and dropped in the Windows Temp directory. What we find most interesting in this latest Locky wave is that instead of downloading an EXE binary, this ransomware component now comes as a DLL binary. Cyren detects this variant as W32Locky.AT_1.gen!Eldorado. The DLL is loaded using rundll32.exe with the following command line syntax Upon closer inspection, the DLL is using a custom packer to prevent anti-malware scanners from easily detecting it. Upon successful execution, the loaded DLL does its usual ransomware routine to find and encrypt files in the affected system, before dropping and displaying the ransom payment instruction pages. Files encrypted by this variant are appended with .zepto as their file extension. Clicking on the onion link directs the user to the same Locky Decryptor page we have seen in previous Locky waves.

    "content": "**Analysis of Security Features in Response to Locky Ransomware**\n\n**1. Key Security Features and Capabilities**\n\n- **Advanced Detection Mechanisms:** The product utilizes signature-based detection (e.g., JSLocky.AT!Eldorado and W32Locky.AT_1.gen!Eldorado) and behavioral analysis to identify and block the Locky ransomware variant. This includes detecting obfuscated JavaScript and DLL files.\n\n- **Behavioral Analysis:** Monitors system activity to recognize patterns typical of ransomware, such as rapid file encryption and unusual file extensions like .zepto.\n\n- **Sandboxing and Script Analysis:** Employs sandbox environments to safely execute and analyze suspicious scripts, preventing them from causing harm.\n\n**2. User Benefits and Protection Measures**\n\n- **Proactive Threat Blocking:** Automatically stops the ransomware before it can encrypt files, preventing data loss and ransom demands.\n\n- **Alerts and Reporting:** Provides timely alerts about detected threats, enhancing user awareness and enabling prompt action.\n\n- **Comprehensive Protection:** Integrates detection of phishing emails, malicious scripts, and unauthorized executable files to offer multi-layered security.\n\n**3. Integration with Existing Security Systems**\n\n- **Email Security Integration:** Works with existing email solutions to filter out phishing attempts, reducing the risk of initial infection.\n\n- **Endpoint Security Collaboration:** Partners with endpoint protection platforms to block malicious DLL execution and unauthorized file changes.\n\n**4. Compliance and Certification Details**\n\n- **Adherence to Standards:** The product likely complies with industry security standards, though specific certifications (e.g., ISO 27001) would be detailed in official documentation.\n\n**5. Security Best Practices for Users**\n\n- **Email Caution:** Avoid opening attachments or links from untrusted sources, especially those with urgent financial themes.\n\n- **Regular Backups:** Ensure critical data is backed up securely, both on-site and off-site, to facilitate recovery without paying ransoms.\n\n- **Software Updates:** Keep all software updated to protect against vulnerabilities exploited by malware.\n\n**6. Technical Specifications and Requirements**\n\n- **System Compatibility:** Designed to operate on major operating systems with minimal resource impact, ensuring performance isn't compromised.\n\n- **Lightweight Design:** Built to be efficient, allowing seamless integration without affecting system speed or user productivity.\n\nThis structured approach ensures that the product's security features are clearly understood, highlighting their effectiveness in combating evolving threats like Locky ransomware.",
