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 fetched code runs with full Node privileges (require, fs, child_process, network). The C2 URL and request headers are concealed by shadowing the local `process` object with fields named `DEV_API_KEY` / `DEV_SECRET_KEY` / `DEV_SECRET_VALUE`, and lib/const.js carries base64-encoded equivalents that decode to a second jsonkeeper.com paste and the header name `x-secret-key`.
