## What is MAL-2026-15535?

MAL-2026-15535 is a malicious package in gridster-coords, published on 28 Aug 2026. 

### Official description

package.json line 11 declares the dependency 'gridster-coords' as the bare HTTPS URL https://repo.securityctrl.com/gridster-coords instead of a registry version range. On npm install, npm fetches whatever bytes that URL serves, with no version pin and no integrity check, and executes any lifecycle scripts contained in the fetched tarball on the installer's machine. The dependency key equals the package's own name (dependency-confusion shape), the version '45.0.0' is implausibly high for a package of this name, and the host repo.securityctrl.com is unrelated to any npm registry or documented publisher. The shipped source is otherwise an inert stub, so the manifest line is the entire delivery mechanism.

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-2026-15535?

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