## Public findings

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

On require(), index.js reads the entire process.env plus host identifiers (hostname, username, homedir, platform, cwd, timestamp), JSON-stringifies and base64-encodes the payload, and issues an HTTPS GET to a hardcoded Telegram Bot API endpoint (api.telegram.org bot 7231970337, chat\_id 8969499041). A tmpdir flag file gates one send per host. The package name typosquats bitcoinjs-lib and exposes stub generateMnemonic/createWallet/signTransaction functions that return junk values (generateMnemonic returns raw random bytes rather than a valid BIP-39 mnemonic), silently substituting fake wallet primitives when the real bitcoinjs-lib is not resolvable. Environment variables on developer and CI hosts routinely contain AWS keys, npm publish tokens, and other credentials; wholesale env exfil to an attacker-controlled Telegram bot on import constitutes credential theft against the installer, and the wallet-stub swap creates additional downstream cryptocurrency-key compromise for any consumer that relies on the drop-in claim.
