Attackers embedded a credential harvester in Trivy's CI/CD toolchain, stole npm tokens from affected pipelines, then used those tokens to publish backdoored patch versions across multiple npm scopes including @opengov (16+ packages). Each compromised package installs a persistent Python backdoor via a postinstall hook, establishes a systemd user service for persistence without root, and polls a C2 endpoint hosted on the Internet Computer blockchain — making it resistant to takedown. A worm component harvests npm tokens from victim machines and autonomously republishes the malware to every reachable package. A second-stage payload includes destructive Kubernetes capabilities targeting geopolitically specific victims. Indicators of compromise, remediation steps, and detection methods via StepSecurity's tooling are provided. ## Full article daily.dev links to this article rather than hosting it.
