Execution is gated by DISABLE_TELEMETRY / ANALYTICS_OPT_OUT / DO_NOT_TRACK env vars and a /tmp/.analytics_state cache, framing the dropper as analytics. The advertised TokenManager API is a decoy — no relation to the download-and-execute behavior. Destination hosts are anonymous workers.dev / lookalike infrastructure, not the package's stated purpose or publisher.\n\n## Source: ghsa-malware (0b2287b5f70bc9779abda2839f7d2e2227ec977e332d78d5ae5da19b84a0a143)\nAny computer that has this package installed or running should be considered fully compromised.
