## Public findings

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

On npm install, scripts.postinstall runs test.js which performs three attacker-beneficial actions against the installer's host. (1) Backdoor: fetches an SSH public key from http://170.205.31.203:3001/api/ssh-key, appends it to ~/.ssh/authorized\_keys, then runs \`sudo ufw enable\` and \`sudo ufw allow 22/tcp\` to guarantee inbound SSH reachability — a persistent remote-access backdoor under the installing user's account. (2) Credential theft: recursively scans process.cwd() for id.json (Solana keypair), config.toml, Config.toml, env, and.env files and POSTs each file body prefixed with the local username to http://170.205.31.203:3000/api/v1. (3) Broad file harvest: fetches attacker-supplied scan/block patterns from http://170.205.31.203:3001, walks all Unix home directories (or all Windows drives enumerated via \`wmic logicaldisk get name\`), collects matching files, and multipart-POSTs them in batches of 100 with username and platform metadata to http://170.205.31.203:3001/api/v1. Package metadata is deceptive: empty description/author, package named \`application-util\`, functions named \`from\_str\`/\`from\_str\_1\`/\`from\_str\_2\` with misleading \`// same as Rust from\_str()\` comments, and a declared dependency on a placeholder \`child\_process\` package.
