## Public findings

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

The package publishes under scope \`@gleamkit/ws\` while copying the \`ws\` package's description, homepage, repository, author, and README verbatim, and bundling the legitimate \`ws\` source so it appears functional. Appended to \`lib/websocket.js\` after the copied WebSocket implementation is a heavily obfuscated payload (base64+RC4 string decoder over a ~700-entry rotated string array, hex-named identifiers, duplicated as two sequential IIFEs) that reconstructs hostnames, paths, environment keys, and spawn arguments at runtime. On every load — \`index.js\` (main) and \`wrapper.mjs\` both pull in \`./lib/websocket\` — the payload issues an HTTPS request to fetch an external binary, AES-256-GCM decrypts it, writes it under \`os.tmpdir()\`, chmods it to 0o755, and spawns it as a detached, \`unref()\`ed child process with \`windowsHide:true\`, then calls \`process.exit\`. A marker env variable gate (\`process.env\[d\]!== e\`) is used to avoid re-entry. Because require/import is the trigger, any project that installs and loads \`@gleamkit/ws\` executes attacker-controlled bytes fetched from a remote host at load time.
