KICS supply chain attack

The Checkmarx KICS GitHub Action was compromised by TeamPCP between 12:58 and 16:50 UTC on March 23, during which users pinning to affected tags were served credential-stealing malware before the repository was taken down. This marks the second major open source security scanner compromised by the same actor within five days, with attribution supported by consistent naming conventions and reuse of the same RSA key. The attack mirrored the Trivy incident, with the attacker staging malicious commits containing a setup.sh payload on a fork, then using a compromised identity to retag all 35 project tags to point to those commits. The malware introduces a new C2 domain (checkmarx.zone, 83.142.209.11), uses a fallback exfiltration method by creating a docs-tpcp repository via stolen GITHUB_TOKENs, and adds Kubernetes-focused persistence alongside credential theft.
