🚨 MistEye TI Alert 🚨 MistEye has detected a highly sophisticated npm worm, "Mini Shai-Hulud," spreading through trusted developer projects like TanStack, UiPath, and DraftLab. The attackers hijacked GitHub credentials to publish malicious, yet seemingly legitimate, package updates. The malware injects a heavily disguised hidden script (router_init.js) that runs silently in the background of CI/CD environments (like GitHub Actions). It is specifically designed to harvest highly sensitive data, including CI/CD secrets, cloud infrastructure keys, and cryptocurrency wallets. The stolen data is then stealthily smuggled out using GitHub's own infrastructure. We have synchronized these critical IOCs with our clients. If your projects utilize the affected packages, immediate action is required: please audit your CI/CD pipelines for the presence of the router_init.js file, rotate all exposed GitHub, cloud, and crypto credentials, and closely monitor your development environments for any unauthorized background activity. As always, stay vigilant!
