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 human reviewer should de-minify or read index.js to confirm whether the HTTP destinations are attacker-controlled, whether process.env contents are sent outbound, and whether any of this fires at install/require time versus only on explicit CLI invocation.\n\nAny computer that has this package installed or running should be considered fully compromised.
