What is MAL-2026-16342?

MAL-2026-16342 is a malicious package in pflag29424, published on 21 Sep 2026.

Official description

index.js (the package's declared main) unconditionally executes on module load: it calls fetch('/profile'), scans the response for a DGA{…} token, and sends either the matched token or the first 300 characters of the response as a query parameter to a hardcoded anonymous collector at https://webhook.site/42c6d937-77c7-42a5-8678-ef06b4501e38. The package has no README, no documented purpose, and a generic throwaway name; the sole effect of loading it is to relay content from the loading context to an attacker-controlled webhook.site endpoint.

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-2026-16342?

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