## Public findings

### 1. High: Osv Malicious Advisory
- **Category:** External Intel
- **Confidence:** 100.0%

This npm package uses the name \`bazelisk\`, colliding with Google's bazelbuild/bazelisk project (referenced in the tarball's source.txt), and self-labels as a 'Security research canary'. Its postinstall script collects the installer's hostname, platform, arch, Node version, package name, and npm lifecycle event and POSTs that JSON payload to https://grqx3qve.instances.poc.jchunt.top/bazelisk at \`npm install\` time. The destination host is unrelated to the real bazelisk publisher. Installer host identifiers and environment fingerprint leave the machine automatically on install, matching a dependency-confusion beacon pattern.
