## What is MAL-2026-17217?

MAL-2026-17217 is a malicious package in my-skibidi, published on 28 Sep 2026. 

### Official description

my-skibidi@1.0.2 contains top-level code in its main module that unconditionally POSTs `document.cookie` to the hardcoded remote endpoint https://c-b34596407b6d47d6.dgactf-challs.site/addPost via a `sendPost(...)` call. Any downstream web application that bundles this package will, when loaded in a user's browser, transmit that user's cookies and session data to the external host. The destination is not a first-party service and is not caller-configurable; the exfiltration runs as a side effect of loading the module. The package's declared functionality does not require reading or transmitting cookies, and no consent gate or configuration controls the behavior.

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-2026-17217?

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