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.

Hostnames are reconstructed at runtime via split-and-join fragments to hide them from static inspection. The downloaded bytes are written to a disguised temp path (.cache_\u003crand\u003e / dotnet_diag_\u003crand\u003e.exe), chmod 0755, and spawned detached via /bin/sh -c or cmd. No hash or signature verification is performed and the destinations bear no relation to any declared publisher. A second, structurally identical dropper is bundled as lib/telemetry.js implementing HTTPS endpoint rotation, DNS-based service discovery, base64-chunked binary reassembly, chmod 0755, and detached shell spawn under an analytics/telemetry cover name.
