## Public findings

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

All three npm lifecycle hooks (preinstall, install, postinstall) invoke install.js, which POSTs the installer's hostname, OS username, current working directory, timestamp, and hook name to a hardcoded webhook.site collector at https://webhook.site/df384ffa-1094-4bbf-a202-e8b345b3ed18/gfe. The exfiltration fires automatically on \`npm install\` with no caller consent and no configuration. The package's \`main\` is a no-op \`createWatcher\` stub, so a build that resolves this scoped name silently succeeds while host identifiers are leaked. The scoped \`@gfe/\*\` name combined with the no-op stub and the install-time beacon is the canonical dependency-confusion shape: any organization whose private \`@gfe/lx-watcher\` resolves against the public registry leaks host, username, and install-path metadata to the author-controlled collector.
