Detection & IOCsextracted from sources · hover to see the quote
- →Raspberry Robin exploits CVE-2024-38196 (Windows CLFS Driver improper input validation) to achieve local privilege escalation to SYSTEM; monitor for unusual CLFS driver interactions from non-privileged processes. ↗
- →Raspberry Robin C2 communication uses ChaCha-20 encryption (migrated from AES-CTR); network traffic to .onion domains using ChaCha-20 framing with a 16-byte RC4 key (8-byte random seed appended to end) is indicative. ↗
- →Raspberry Robin embeds intentionally corrupted TOR onion C2 domains that are dynamically corrected at runtime via a hardcoded per-sample algorithm; static extraction of C2 domains from the binary will yield invalid addresses. ↗
- →Detect Raspberry Robin DLLs using the threat name Win32.Worm.RaspberryRobin in sandbox/AV telemetry. ↗
- →CVE-2024-38196 exploitation grants SYSTEM privileges via the Windows Common Log File System Driver; monitor for privilege escalation events originating from the CLFS driver on unpatched systems. ↗
- ·RC4 key seed position and hardcoded key bytes vary per sample/campaign; the 8-byte random seed is now appended to the END of the 16-byte RC4 key (previously prepended). CRC-64 initial values are also randomized per sample/campaign, making static signature matching on these fields unreliable across campaigns. ↗
- ·The C2 domain correction algorithm is different per sample/campaign as of early 2025, meaning extracted onion domains from one sample cannot be directly applied to another without accounting for the per-sample correction routine. ↗
- ·Memory mapping offsets used for communication between Raspberry Robin's core module and TOR module vary per sample/campaign, complicating memory-based detection rules. ↗
