The malware Raspberry Robin has evolved to utilize new one-day exploits for local privilege escalation, making it harder to detect and analyze. It serves as an initial access facilitator for other malicious payloads and has ties to various e-crime groups. The threat actors behind it purchase exploits from the dark web, demonstrating a significant threat level.
From the meeting notes, the key takeaways are:
1. Raspberry Robin malware is using new one-day exploits for local privilege escalation, indicating access to exploit sellers or quick in-house development of exploits.
2. The malware is being attributed to a threat actor named Storm-0856, previously known as DEV-0856, and is associated with various entry vectors and other e-crime groups.
3. The operators are implementing additional anti-analysis and obfuscation techniques to make it harder to detect and analyze.
4. Raspberry Robin is using one-day exploits, including CVE-2023-36802, which were advertised on dark web forums before their public disclosure.
5. The threat actors appear to purchase these exploits rather than developing them in-house based on the way they are used and obfuscated.
6. The initial access pathway is now leveraging rogue RAR archive files hosted on Discord, and the lateral movement and command-and-control communication methods have been modified in newer variants.
These points highlight the evolving tactics and capabilities of the Raspberry Robin malware and the threat posed by its operators.
