## Public findings

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

Package impersonates the bitcoinjs/bip39 project (author field set to 'bitcoinjs-lib') and ships a postinstall.js that runs on \`npm install\`. The script collects host/user identifiers and a curated list of sensitive environment variables (including NPM\_TOKEN, NODE\_AUTH\_TOKEN, GITHUB\_TOKEN, AWS\_\* keys, and wallet-related PRIVATE\_KEY/MNEMONIC/SEED\_PHRASE), enumerates ~/.ssh, reads ~/.npmrc and ~/.gitconfig, probes Chrome/Firefox profile artifacts and crypto wallet directories, and shells out to \`npm whoami\` and \`git config\`. The collected JSON is transmitted to two hardcoded destinations: the Telegram Bot API (bot token and chat\_id 7231970337 embedded in the script) and a POST to 40f955f39128bd79-178-249-214-24.serveousercontent.com/collect. Exfiltration is delayed by a randomized setTimeout (1500 + rand\*2000 ms) and the module re-exports./index.js to appear legitimate.
