This matches the npm-lifecycle-external-fetch and credential/telemetry exfiltration patterns (findings a static pattern match, a static pattern match, a static pattern match, a static pattern match, a static pattern match). the analysis confirms contextually that the script performs reconnaissance exfiltration to a non-registry collector, and config.unsafe-perm is set to ensure execution. the analysis further notes that the declared main entrypoint is missing and the tarball contains only package.json — the package exists solely to trigger the beacon, with no legitimate runtime functionality. Self-identification as a 'PoC' does not change the risk to an unintended installer (e.g., via dependency confusion).\n\n## Source: ghsa-malware (66a5014b00cbe1f0b68f513878acb21a0801758710524c715d837ef999ad3752)\nAny computer that has this package installed or running should be considered fully compromised.
