The beacon fires automatically on `npm install` without user consent. Although the package description self-labels as an \"authorized bug bounty PoC,\" any unintended installer has their host fingerprint exfiltrated to an attacker-controlled endpoint. The combination of internal-scope impersonation, inflated version, and install-time beacon to a bare IP is the canonical dependency-confusion attack shape.\n\n## Source: ghsa-malware (79e7444404a6d66614a51f820700524fc124a5b9657f91d56f49c69ad1edd148)\nAny computer that has this package installed or running should be considered fully compromised.
