On August 19, 2024, Microsoft identified a North Korean threat actor exploiting a zero-day vulnerability in Chromium, now identified as CVE-2024-7971, to gain remote code execution (RCE). Microsoft researchers assess with high confidence that the observed exploitation of CVE-2024-7971 can be attributed to a North Korean threat actor targeting the cryptocurrency sector for financial gain.
Microsoft ongoing analysis and observed infrastructure lead them to attribute this activity with medium confidence to Citrine Sleet. The researchers note that while the FudModule rootkit deployed has also been attributed to Diamond Sleet, another North Korean threat actor, Microsoft previously identified shared infrastructure and tools between Diamond Sleet and Citrine Sleet, and our analysis indicates this might be shared use of the FudModule malware between these threat actors.
