Summary

npx-oob-package ships bin/cli.js which is also declared as the package main. On both CLI invocation and any require()/import of the package, the module collects local identifiers (whoami / os.userInfo(), os.hostname(), os.platform()) along with the package name and POSTs them via fetch() to a hardcoded Cloudflare Workers endpoint at https://oobme.kunalsharma0553.workers.dev/r/7bq6fz3l15r9. The callback destination is not configurable and there is no user consent or opt-out. The package presents as an out-of-band (OOB) beacon consistent with dependency-confusion or pentest-style reconnaissance, causing installer host and user identifiers to leave the machine to an author-controlled endpoint on install-triggered require or CLI use.
