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.

Anti-analysis techniques include split-string require(\"child_\"+\"process\"), split-property fs[\"chmod\"+\"Sync\"], array-join hostname assembly, and DNS TXT-record staged payload delivery.
