Immediate action
Remove the package, then rotate any secrets the build/runtime could reach.
npm uninstall strapi-plugin-maylog-meeb

What this malware does

The package's postinstall.js lifecycle script executes automatically on npm install and spawns a python3 reverse shell that connects to the hardcoded remote endpoint 14.225.210.85:80 and attaches an interactive sh PTY to the socket, giving the operator of that endpoint full shell access to the installer's host. Prior to the connect, the script collects host identifiers (os.hostname(), os.userInfo().username, process.pid) and writes them to /tmp/postinstall-revshell.log; those identifiers are also exposed to the remote endpoint once the shell attaches. The script retries on failure. The package name and description masquerade as a Strapi audit-log plugin; no functionality in the tarball corresponds to that stated purpose.

Detection & response playbook

Backdoor / remote access

  1. Find it

    Search your lockfiles and build artifacts for strapi-plugin-maylog-meeb (version 3.6.8).

  2. If you installed it — respond

    strapi-plugin-maylog-meeb establishes remote access, so treat any host that installed it as fully compromised. Isolate the machine, remove the package, rotate all credentials it could reach, and rebuild from a trusted image rather than cleaning in place — a backdoor may have planted additional persistence.

  3. Did it already run?

    If strapi-plugin-maylog-meeb was installed, its post-install payload may already have run. Removing the package does not undo that — check outbound connections and credential use from the install window onward.
