Description

The xo-tracking npm package version 88.8.9 contains malicious code that installs a dependency from a custom domain which executes an information stealer during installation. This malware targets sensitive tokens related to npm, git, and CI/CD environments. Any system with this package installed should be considered fully compromised, and all secrets and keys stored on that system must be rotated immediately from a different, secure machine. Removing the package alone may not eliminate all malicious software introduced.
