## What is MAL-2026-13924?

MAL-2026-13924 is a malicious package in internallib_v392, published on 12 Aug 2026. 

### Official description

index.js exports a function that invokes /bin/bash -c to curl a remote reverse-shell script from reverse-shell.sh and pipe it to sh, targeting the hardcoded IP 10.0.72.234 on port 443. When the exported API is called by a consumer, the installer's host fetches and executes attacker-controlled shell code, granting the attacker at 10.0.72.234:443 a reverse shell on the installer's machine. The package metadata is minimal (empty description/author) and the package name has a typosquat-like shape, consistent with a malicious drop rather than a legitimate library.

Any computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.

## What should I do about MAL-2026-13924?

Remove the package from your dependencies and lockfiles, then rotate any secrets on machines where it was installed.
