Summary
Malicious code in cloudflare_module (npm)
Details
cloudflare_module@1.0.1 is a typosquat of Cloudflare branding whose only functional code is an install- and import-time beacon. beacon.cjs defines BEACON = "http://185.158.107.175:8787/_ah/dc" and a fire() function that POSTs a JSON payload containing os.hostname(), __dirname (installPath), process.cwd(), process.version and the package name to that hardcoded bare-IP HTTP endpoint. fire() is invoked from the package's postinstall script, so it runs automatically on `npm install`, and from the main module, so it also runs on `require('cloudflare_module')`. The package's main entry exports a Proxy of no-op functions (`module.exports = new Proxy({}, { get:... return _noop; })`) with a generic "Compatibility shim" description, so the package provides no legitimate functionality — the exfil beacon is its sole behavior. The destination is a bare IPv4 address on a non-standard port over cleartext HTTP, with no relationship to Cloudflare or any documented publisher. Host identity, install path and working directory shipped to an attacker-controlled collector constitute reconnaissance of installer environments suitable for targeted follow-on supply-chain exploitation.
