## What is MAL-2026-11537?

MAL-2026-11537 is a malicious package in discord-vibegrations-api-natives, published on 4 Aug 2026. 

### 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.
