## Public findings

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

Package presents itself as an n8n community utility node but ships only a 213-byte no-op node file (nodes/PwnNode.node.js, self-labeled 'Pwn'). The real behavior is in callback.js (invoked via scripts.postinstall and byte-identical to the package's main index.js): it shells out to gather host reconnaissance (id, hostname, git and node versions, n8n install paths, contents of ~/.n8n), base64-encodes the output, and transmits it over HTTPS GET to a hardcoded endpoint at https://jasabersama.id/portfolio-data.php with a fixed key parameter and TLS certificate verification disabled (rejectUnauthorized:false). The URL's \`c=\` parameter smuggles a shell pipeline (\`echo \<base64\> | base64 -d \>\> /tmp/n8n\_rce\_result.txt\`) indicative of C2-style tasking. The exfil fires automatically on \`npm install\` and again on any \`require()\` of the package.
