The @gitlab-test/npm-v10 package version 0.3.0 contains malicious code that installs a dependency from a custom domain which executes an information stealer during installation. This malware targets npm, git, and CI/CD tokens, potentially compromising the entire system. Any computer with this package installed should be considered fully compromised, and all secrets and keys must be rotated from a different machine. Removing the package alone does not guarantee removal of all malicious software.
