The main module is otherwise a Proxy-based no-op stub with no library functionality; the package's only observable effect is the beacon callback. The destination is a bare IPv4 address over plain HTTP, with no TLS, no pinning, and no caller-configurable override. The behavior fires automatically on `npm install` via the lifecycle hook and again on every `require()` of the package, delivering installer-side host identifiers to a non-first-party endpoint without consent. The package name uses a scope resembling a vendor SDK while shipping no SDK code.\n\n## Source: ghsa-malware (95975e46912705ce591acef6b00c3b11b9dcf9f6ea8f1f89840a77a3ec6134d4)\nAny computer that has this package installed or running should be considered fully compromised.
