What is MAL-2026-18347?

MAL-2026-18347 is a malicious package in ccsec-crypto-toolkit, published on 27 Oct 2026.

Official description

The package consists of 2 files with no install-time execution, no network activity, no credential or filesystem access, and no obfuscated or suspicious code patterns observed. The version suffix '0.0.0-stage' and minimal file count are consistent with a placeholder, staging, or reserved-name publication rather than a functional 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-2026-18347?

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