That file resolves the `os` and `dns` core modules indirectly through `module.constructor._load` with char-code-array names to avoid appearing in a normal `require` graph, then reads `os.userInfo().username`, `os.hostname()`, and the basename of `process.cwd()`. Those values are concatenated as DNS labels together with a hex-decoded destination domain and issued as a `dns.resolve4` query to a subdomain of `oob.algamil7x.xyz`, a DNS-based out-of-band exfiltration collector. The destination hostname and the core-module names are stored as char-code arrays and decoded at runtime, and the logic is split across helper files (b2e6f8.js/c3f7a9.js) under a `telemetry/probe` cover directory. Every `npm install` of this version therefore leaks the installing user's username, machine hostname, and working-directory name to an attacker-controlled domain, and the obfuscation shows the destination and API surface were deliberately hidden. ## Source: ghsa-malware (4c31038f30e69d193bebbd24c2516ac96e345889aa0e9c81a9f35afca8b7c044) Any computer that has this package installed or running should be considered fully compromised.
