This time we have seen a well-known RTF exploit, CVE-2017-11882, being used by threat actors to deliver this malware to unsuspecting users. The RTF documents, detected by Cyren as RTFCVE-2017-11882.S.gen!Camelot, have file sizes that range between 400KB up to 4.5MB, but the valid RTF objects only use up to around 10-12KB, which means a large part of the document is considered as garbage data to simply obfuscate and hide the exploit. A quick view of the RTF document using the rtfobj tool shows that there are 2 embedded objects, a VBScript and an Equation.3 object, which is still widely seen as being exploited in the wild. We have confirmed that the Equation.3 object is indeed exploited and used as the launcher for the embedded VBScript, with its main purpose of downloading and executing a base64 encoded Powershell script component from cdn.discordapp.com. The abuse on Discords content delivery network for purposes of serving malicious components is also evident after decrypting similar variants of the RTF exploits from this campaign. Shown below are snippets of the code and their decoded formats. Reversed Decoded The downloaded data from Discords CDN, is a base64 encoded Powershell script that behaves similarly to a variant that was documented in November of 2020   , including the bypass of AMSI integration as highlighted in the decoded Powershell payload show below. After bypassing AMSI a .NET compiled DLL encoded and stored in the variable PROCESS_INFORMATION is decompressed and loaded as an assembly, which eventually executes a variant of Formbook using the code shown below. Below is a view of the exported function from the loaded .NET compiled DLL used to execute the final malware payload. Cyren detects these components as W32Formbook.A.gen!Eldorado and W32MSIL_Injector.XD.gen!Eldorado.

    "content": "**Analysis of Formbook Malware and RTF Exploit Security Content**\n\n1. **Key Security Features and Their Benefits to Users:**\n   - **Exploit Detection:** Tools like `rtfobj` help identify embedded malicious objects (VBScript and Equation.3) within RTF files, crucial for early detection.\n   - **Antivirus Signatures:** Cyren detects these threats as `W32Formbook.A.gen!Eldorado` and `W32MSIL_Injector.XD.gen!Eldorado`, aiding in malware identification and blocking.\n   - **Traffic Monitoring:** Identifying and blocking malicious URLs using IoCs helps prevent download of malicious components.\n\n2. **Compliance Certifications and Regulatory Adherence:**\n   - Ensure compliance with patching standards to address vulnerabilities like CVE-2017-11882, mitigating risks from known exploits.\n   - Develop incident response plans for regulated industries, essential for compliance and timely reporting of breaches.\n\n3. **User-Focused Security Recommendations:**\n   - **Awareness Training:** Educate users to be cautious with unsolicited emails, especially those with RTF attachments, to prevent initial infection.\n   - **Avoid Suspicious Files:** Advise against opening RTF files from unknown sources, reducing the risk of exploit delivery.\n\n4. **Technical Security Implementation Details:**\n   - **Network Monitoring:** Implement traffic analysis to detect and block communications with known malicious domains, enhancing network security.\n   - **Office Document Analysis:** Use tools to inspect Office files for embedded malicious objects, preventing exploit execution.\n   - **Advanced Security Measures:** Employ solutions beyond AMSI, such as behavioral analysis, to detect evasion techniques.\n\n5. **Data Protection Measures:**\n   - **Regular Backups:** Implement secure, offsite backups to mitigate data loss from potential breaches.\n   - **Encryption:** Protect data at rest and in transit to prevent unauthorized access in case of theft.\n\n6. **Best Practices for End Users:**\n   - **Software Updates:** Keep all software updated to patch vulnerabilities and protect against exploits.\n   - **Antivirus Use:** Install reputable antivirus with heuristic scanning to detect novel threats.\n   - **Network Security:** Use firewalls and intrusion detection systems to monitor and block malicious traffic.\n   - **Safe Computing:** Avoid enabling macros in Office documents from untrusted sources, a common attack vector.\n\n**Conclusion:**\nThe analysis underscores the importance of multi-layered security, combining technical measures, user awareness, and regulatory compliance to combat evolving threats like Formbook. By understanding the exploit mechanisms and implementing these strategies, organizations can enhance their resilience against such attacks.",
