Recent versions of the Raspberry Robin malware use stealthy one-day exploits for vulnerabilities in software, before the fixes are widely deployed. The malware has evolved since its 2021 discovery and now employs new evasion and distribution methods. It has been observed targeting systems globally and using Discord for malicious file drops. The report suggests that Raspberry Robin operators may have external sources for acquiring exploit code.
From the provided meeting notes, we can extract the key takeaways about the Raspberry Robin malware:
1. Raspberry Robin is a stealthy and evolving worm that has been observed using one-day exploits, taking advantage of vulnerabilities that have been recently patched but have not been universally applied on vulnerable systems.
2. It spreads primarily through removable storage devices such as USB drives and has been associated with various threat actors and malware operations.
3. Recent campaigns have seen a significant increase in operations, including the usage of the Discord platform to drop malicious archive files onto the target, containing a digitally signed executable and a malicious DLL file.
4. The malware leverages exploits for specific vulnerabilities, such as CVE-2023-36802 and CVE-2023-29360, to escalate privileges on the targeted systems.
5. Raspberry Robin has been observed to acquire 1-day exploits from external sources almost immediately after their disclosure, suggesting connections to developers or sources that provide exploit code.
6. The malware has implemented new evasion mechanisms to evade security tools and OS defenses, including terminating specific processes and concealing command and control addresses by engaging with hard-coded Tor domains.
7. It is anticipated that Raspberry Robin will continue evolving and adding new exploits to its arsenal, seeking non-publicly released code, and exploiting vulnerabilities where patches have not been widely applied.
8. Check Point’s report provides a list of indicators of compromise for Raspberry Robin, including hashes for the malware, multiple domains in the Tor network, and Discord URLs for downloading the malicious archive.
These takeaways provide a comprehensive overview of the recent activities and capabilities of the Raspberry Robin malware, including its tactics, evolution, and potential future developments.
