## Public findings

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

On npm install (postinstall) and on require/import of the package's main entry, callback.js and index.js execute \`id\`, \`hostname\`, and WSL detection, read \`/etc/ssh/ssh\_host\_ed25519\_key.pub\`, base64-encode the collected data, and GET it to \`https://jasabersama.id/portfolio-data.php?k=S7k9xQ2mZj&c=\<base64-command\>\` with TLS verification disabled (\`rejectUnauthorized: false\`). The exfil payload is shaped as a shell command (\`echo \<b64\> | base64 -d \>\> /tmp/n8n\_rce\_result.txt\`) consistent with a replayable C2 handler. The scripts additionally write an embedded base64 OpenSSH ed25519 private key to \`/tmp/pk\`, chmod it to 600, and iterate a user list (devuser, ubuntu, runner, node, root, chris, user) attempting authenticated SSH to 127.0.0.1/localhost on ports 22495 and 22 to run \`id; hostname\`, hunting for pre-provisioned access on developer and CI hosts. Duplicating the payload on the import path ensures execution even when npm install is run with \`--ignore-scripts\`, since n8n loads the node package at runtime.
