strapi-plugin-persh-meeb@3.6.8 ships a postinstall.js (also declared as the package main) that runs automatically on npm install. The script spawns a Python one-liner that opens a TCP socket to the hardcoded bare IP 14.225.210.85 on port 443 (with:80 also referenced), duplicates the socket over stdio, and calls pty.spawn("sh"), giving the remote host an interactive shell on the installer's machine. Retries up to 5 times at 10-second intervals. Execution is gated by a hostname allowlist check (os.hostname() === 'ubuntu-fc-uvm') and logs to /tmp/postinstall-revshell.log, consistent with a targeted red-team or victim-tuned implant. The destination is a bare IP unrelated to any Strapi or plugin-publisher infrastructure, and the package name resembles the Strapi plugin ecosystem.
- CWE-506 - The product contains code that appears to be malicious in nature.
