The durablefunctionsmonitor.react npm package version 0.1.3 contains malicious code that installs a dependency from a custom domain which runs an information stealer during installation. This malware targets sensitive tokens related to npm, git, and CI/CD environments. Systems with this package installed should be considered fully compromised, and all secrets and keys stored on those systems must be rotated immediately from a separate, secure machine. Removing the package alone may not eliminate all malicious software introduced.
