nam-os-a-man@99.9.9

The package declares a postinstall hook that runs index.js on npm install. index.js collects the installer's OS username (os.userInfo().username), hostname (os.hostname()), and current working directory, and POSTs them as JSON to a hardcoded webhook.site collector at https://webhook.site/9bbc2089-62c5-46d8-bfaf-f238cc8d0275. Errors are swallowed so the beacon runs silently. The package ships no library functionality (empty description, empty author, no README), the name 'nam-os-a-man' is a fragmented/typosquat-style identifier, and the version is pinned to 99.9.9 — a common dependency-confusion sentinel. The install-time exfiltration of host identity to an attacker-controlled webhook collector is the entire purpose of the package. ## Source: ghsa-malware (1ec40b39b2e4bb327d6dcd7fa5e8b3b6aedb4f1aa45666f40f30f08bec8e4a3d) Any computer that has this package installed or running should be considered fully compromised.
