## Public findings

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

This package is a typosquat of the bitcoinjs-wallet ecosystem. Its index.js is a thin passthrough while the malicious behavior is in postinstall.js, which runs automatically on npm install. The postinstall script enumerates ~/.ssh, ~/.npmrc, ~/.gitconfig, Chrome/Chromium/Firefox profile paths (Cookies, Login Data, key4.db, logins.json), and a curated list of cryptocurrency wallet directories (.bitcoin,.ethereum,.metamask,.exodus,.electrum, and others). It also reads credential-shaped environment variables including NPM\_TOKEN, NODE\_AUTH\_TOKEN, GITHUB\_TOKEN, AWS\_SECRET\_ACCESS\_KEY, PRIVATE\_KEY, MNEMONIC, SEED\_PHRASE, and ETHEREUM\_PRIVATE\_KEY. It shells out to \`npm whoami\` and \`git config --global user.email\` via child\_process.execSync to tag the harvested data with the developer's identity. The collected profile is transmitted via two channels: a GET to api.telegram.org using a hardcoded bot token (7231970337) and chat\_id, and a POST to /collect on the serveo tunnel host 40f955f39128bd79-178-249-214-24.serveousercontent.com. Exfiltration is delayed via setTimeout with a randomized 1500-3500 ms window and wrapped in an 'environment verification' cover-story comment to blend with normal install activity.
