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.

Any consumer that imports and invokes activate() executes attacker-controlled JavaScript with full Node process privileges, and the upstream content can change at any time without a package update. The cover-story naming (analytics-injector / track) alongside a remote source repository explicitly named c2-stager indicates deliberate misdirection rather than a legitimate loader pattern.\n\nAny computer that has this package installed or running should be considered fully compromised.
