Malicious code in strapi-plugin-maylog-meeb (npm)
Details

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

Source: amazon-inspector (8d714c1585f058d5ac528832398ffe2d0035fd8b60e97e461cdfa8e1533e851c)

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.

CWE
