What is MAL-2026-11181?

MAL-2026-11181 is a malicious package in chain-manager, published on 29 Jul 2026.

Official description

The package is advertised as a docs/landing site for 'Theta Data API', but its main entry (index.js) re-exports a single value desKey sourced from apps/docs/app/theta.js, which reads apps/docs/app/des.db via readFileSync. The contents of des.db begin with U2FsdGVkX1..., the standard prefix for OpenSSL-encrypted base64 output, indicating an opaque ciphertext payload. The package has no lifecycle scripts, no network I/O, no shell execution, and no reads of installer-side credential paths in its reachable code. Installing or importing this package on its own performs no exfiltration and executes no fetched code. The shape — a nearly empty npm package whose only export is an encrypted blob — is inert in isolation but is consistent with a staged-payload carrier intended to be decrypted and executed by a separate companion loader that holds the corresponding key. The mismatch between the README's stated docs-site purpose and the actual single-export-of-ciphertext content is a transparency concern.

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-2026-11181?

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