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.

A cover-story surrounds the dropper: an 'analytics_state' lock file, a DISABLE_TELEMETRY env gate that does not actually disable execution, a node-fetch/2.6 User-Agent, and an unreachable lib/telemetry.js presenting an 'Analytics SDK' facade. The delivered binary is attacker-controlled, unpinned, unsigned, mismatched to any documented package purpose, and executed detached on the installer's host at import time.\n\nAny computer that has this package installed or running should be considered fully compromised.
