If it is present, remove it, regenerate the lockfile with the project's package manager, and replace whatever it was used for.\n3. List any CI runners, developer machines or containers that installed it, so their secrets can be rotated.\n4.

The agent enters an infinite polling loop against registry.npmjs.org, reading the package's own dist-tags for base64-encoded commands, decoding them, and executing them via `bash -c` on the installer's host. Command output is then base64-encoded and exfiltrated by publishing throwaway public npm packages containing the encoded output in the `description` field, using a hardcoded npm auth token embedded in install.js. The same token is written into the installer's global npm config at ~/.npmrc via `npm config set //registry.npmjs.org/:_authToken`, hijacking the installer's package manager credentials. Base64 encoding is used on both the inbound command channel and the outbound result channel to evade casual inspection of registry metadata.\n\nAny computer that has this package installed or running should be considered fully compromised.
