Summary
Malicious code in strapi-plugin-conresh-meeb (npm)
Details

-= Per source details. Do not edit below this line.=-

Source: amazon-inspector (d117fca143f7c8f02261755b923b29cae47f8fdcca2f69f169e26a5601b3661a)

The package declares a postinstall lifecycle hook ("postinstall": "node postinstall.js") that executes on every npm install. postinstall.js invokes child_process.exec with a bash reverse-shell command connecting the installer's host to the hardcoded remote endpoint 14.225.210.85:80 via /dev/tcp, redirecting stdio to give the remote party an interactive shell on the installer's machine. Execution is gated by a hostname allowlist (matching 'ubuntu-fc-uvm'), and a retry loop plus a log file at /tmp/postinstall-revshell.log indicate a persistent, targeted deployment. The plugin name mimics the Strapi plugin namespace but ships no plugin functionality relevant to that framing.

CWE
