According to MistEye, a threat monitoring system under the blockchain security firm SlowMist (@SlowMist_Team), a highly sophisticated npm worm named "Mini Shai-Hulud" is spreading through well-known developer projects such as TanStack, UiPath, and DraftLab. Attackers have compromised GitHub credentials and published malicious packages disguised as legitimate updates, embedding a hidden script, router_init.js, which silently executes in CI/CD environments like GitHub Actions to steal CI/CD secrets, cloud infrastructure credentials, and cryptocurrency wallet information, using GitHub’s own infrastructure to exfiltrate data. SlowMist has shared relevant threat intelligence (IOCs) with its clients and recommends that projects using the affected packages immediately scan their CI/CD pipelines for the presence of router_init.js, rotate all exposed GitHub, cloud service, and cryptocurrency credentials, and continuously monitor development environments for anomalous background activity.
