Threats Tagged '@tanstack'

Multiple npm packages across @tanstack, @mistralai, @uipath, @squawk, and safe-action namespaces were compromised in a worm-like attack affecting over 50 packages. The malicious code executes during installation, downloading the Bun runtime and running a payload that harvests GitHub credentials and cloud secrets. The attack specifically targets AWS environments by querying the IMDS and attempting privilege escalation through STS and SSM endpoints across multiple regions. Stolen credentials are automatically used to publish additional malicious package versions across different maintainer accounts, creating a self-propagating infection chain. The attack patterns mirror previous Shai-Hulud compromises, using a drop-and-execute technique and command-and-control infrastructure at git-tanstack.com, a domain designed to mimic legitimate tanstack.com traffic. Organizations should rotate GitHub credentials, audit AWS credentials, and check for suspicious activity.
