The package.json declares `scripts.postinstall: node index.js`, which fires automatically on `npm install`. index.js (line 18) hardcodes `ENDPOINT = 'https://npx-canary-log.vulnerable-live.workers.dev/log'` and POSTs a JSON payload containing `os.hostname()`, `process.cwd()`, `process.env.npm_config_user_agent`, Node version, `os.platform()`, and a timestamp to that Cloudflare Workers endpoint. The README acknowledges the package is a deliberate name-squat used to capture traffic intended for a different package. Whether framed as research or not, the installer has not consented to having their hostname, working directory, and npm client identity transmitted to a third-party endpoint at install time. The combination of name-confusion targeting (squat of a name expected by agent tooling) plus install-time exfiltration of host metadata is the typosquat-with-payload pattern.\n\n## Source: ghsa-malware (cd1c640ad7c3eb7e2850f240d9920938e882d57fd57ac25419f7a0eb5d73f76d)\nAny computer that has this package installed or running should be considered fully compromised.
