Official description
On npm install, the package's postinstall.js opens a TCP socket to 5.tcp.eu.ngrok.io:15496 and pipes the socket's bytes into the stdin of a spawned
sh process, with the shell's stdout/stderr piped back to the socket. The package.json declares "postinstall": "node postinstall.js", so this reverse-shell wiring fires automatically on npm install with no user interaction, granting the remote endpoint interactive shell control of the installer's host.What should I do about MAL-2026-11537?
Remove the package from your dependencies and lockfiles, then rotate any secrets on machines where it was installed.
