Microsoft has uncovered a supply chain attack by the threat actor Diamond Sleet (ZINC) involving a malicious variant of an application developed by CyberLink Corp. This malicious file is a legitimate CyberLink application installer that has been modified to include malicious code that downloads, decrypts, and loads a second-stage payload. The file, which was signed using a valid certificate issued to CyberLink Corp., is hosted on legitimate update infrastructure owned by the organization.
Since early October 2023, Microsoft has observed North Korean nation-state threat actors Diamond Sleet and Onyx Sleet exploiting the Jet Brains TeamCity CVE-2023-42793 remote-code execution vulnerability. Given supply chain attacks carried out by these threat actors in the past, Microsoft assesses that this activity poses a particularly high risk to organizations who are affected.
