## Public findings

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

On require(), index.js collects the host's hostname, username, home directory, platform, current working directory, and the entire process.env, base64-encodes the payload, and transmits it via https.get to api.telegram.org using a hardcoded bot token and chat\_id 8969499041. A marker file in the OS temp directory is used to gate repeated sends. process.env routinely carries CI tokens, cloud credentials, and API keys on developer and build-system machines, so this constitutes bulk credential theft on install/import. The package self-describes as a drop-in replacement for @ethersproject/abstract-signer and delegates to it when present, using impersonation of a widely-used Ethereum library as the lure to increase installations.
