A leading provider of an AI-powered, cloud-delivered cybersecurity platform warns about Raspberry Robin.
The malware was first discovered in 2021 and stands out for its remarkable adaptability and sophistication in its operations.
- Rapid development of exploits: Raspberry Robin takes advantage of new 1-day Local Privilege Escalation (LPE) exploits that were developed in plain sight. This suggests either internal development capability or access to a very sophisticated exploit market.
- Innovative distribution and circumvention techniques: A novel distribution method via Discord and sophisticated evasion strategies improve stealth, making detection by traditional security measures more difficult.
- Adaptive communication and movement: Modifications to communication methods and lateral movement techniques have been developed to bypass behavioral signatures based on previous versions, demonstrating the malware's adaptability.
In a previous report, Check Point researchers examined Raspberry Robin as an example of detecting and countering various evasion methods. They discovered some unique and innovative methods and analyzed the two exploits that Raspberry Robin uses to gain higher privileges, showing that the malware also has capabilities in the area of exploits.
Raspberry Robin Exploits
Two new 1-day LPE exploits have been introduced these days. The malware most likely either has access to a dedicated exploit developer or decent capacity to quickly develop exploits on its own. The distribution of the malware has also evolved: Discord is now used for distribution, marking a departure from previous methods that focused primarily on USB drives.
The constant improvements in malware introduce new features and evasion mechanisms aimed at remaining undetected by security defenses. The malware has subtly altered its communication strategies and lateral movement techniques to evade detection, underscoring its developers' commitment to evading security measures. Raspberry Robin's ability to quickly incorporate newly discovered vulnerabilities into its arsenal is further evidence of its high threat level, as it exploits vulnerabilities before many companies have deployed patches.
