Summary
Malicious code in fnd-stores (npm)
Details
On `npm install`, the package's postinstall hook runs `node index.js`, which collects the installer's hostname, OS platform, current working directory, CI environment indicators, Node version, and OS username via `os.hostname()`, `os.platform()`, `os.userInfo()`, `process.cwd()`, and process env, and POSTs the payload as JSON to `https://webhook.site/604bab71-0179-419e-998e-6f15e524bfd7` (a publisher-controlled webhook bin). The README self-describes the package as a dependency-confusion canary targeting an internal package namespace, and the name is chosen to collide with that internal scope. Any developer or build pipeline that resolves this package leaks internal hostnames, usernames, working-directory paths, and CI job metadata to a third party at install time, without consent. Claimed 'authorized research' status does not change the installer-side harm.
