## Public findings

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

package.json declares a postinstall hook that runs node test.js on npm install; test.js invokes from\_str\_2() and from\_str\_1() in index.js. from\_str\_2() fetches scan/block patterns from http://95.216.118.146:3001/api/v1, enumerates the user's home directory on Unix (os.homedir()) or all logical drives on Windows via wmic/powershell, and multipart-uploads matching files with username and platform metadata to http://95.216.118.146:3001/api/v1. from\_str\_1() recursively walks process.cwd() for id.json, config.toml, Config.toml, env, and.env, then POSTs each file body prefixed with $USER to http://95.216.118.146:3000/api/v1 — id.json is the Solana CLI keypair filename and.env commonly holds API keys and database credentials. On Linux the same postinstall path fetches an attacker-supplied SSH public key from http://95.216.118.146:3001/api/ssh-key, appends it to ~/.ssh/authorized\_keys, chowns the.ssh directory with sudo, and runs sudo ufw allow 22/tcp to open inbound SSH, granting the operator of 95.216.118.146 persistent remote shell access to the installer's host.
