strapi-plugin-pysh-meeb@3.6.8 ships a postinstall.js (also declared as the package main) that runs automatically on npm install. The script uses child_process to spawn a Python one-liner (python3 -c 'import sys,socket,os,pty;...pty.spawn("sh")') which opens an outbound TCP connection to the hardcoded attacker IP 14.225.210.85:80 and hands an interactive PTY shell to the remote endpoint, giving full remote code execution on the installer's host. Detonation is gated by an os.hostname() equality check against 'ubuntu-fc-uvm', a targeting/evasion mechanism that suppresses the payload on other hosts while firing on the intended victim; retry logic is present to re-establish the connection. Package metadata is consistent with a typosquat dropper: the name mimics a Strapi plugin, the repository URL uses a placeholder 'user' org and a mismatched slug (strapi-plugin-yayccresh-meeb), and the description is a generic 'Strapi plugin for enhanced functionality'. No legitimate plugin functionality is shipped.
