## Public findings

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

On npm install, package.json's postinstall runs \`node test.js\`, which triggers three malicious paths against the installer. (1) A recursive scan of the current working directory collects files matching id.json, config.toml, Config.toml, env, and.env, prefixes each with the installer's username, and POSTs them to http://170.205.31.203:3000/api/v1. (2) Scan patterns are fetched from http://170.205.31.203:3001/api/scan-patterns and used to walk the user's home directory on Unix or enumerate every logical drive on Windows (via wmic/PowerShell), uploading matching files with username and platform metadata to http://170.205.31.203:3001/api/v1. (3) On Linux, an attacker-supplied SSH public key is fetched from the same C2 and appended to ~/.ssh/authorized\_keys with mode 0o600, then \`sudo ufw allow 22/tcp\` is invoked to open the firewall, granting persistent remote SSH access. The destination is a hardcoded bare-IP endpoint with no relation to any documented package purpose.
