What is MAL-2026-11488?
MAL-2026-11488 is a malicious package in test-dev-boot, published on 1 Aug 2026.
Official description
On require/import (and when invoked as a bin), the package's main entrypoint detects Windows and installs an HKCU\Software\Microsoft\Windows\CurrentVersion\Run entry named 'WindowsAutoUpdate' that points at a launcher.vbs staged above the package root via wscript.exe, providing auto-start persistence on every user login. In the same import-time flow it fires background tasks sendExtInfo() and createAndSaveArchive() (host recon + archive-and-upload grabber) sourced from the declared sibling dependencies test-dev-host and test-dev-sync, which the local module re-exports and invokes (main, handleConnection, mainLoop, sendExtInfo, createAndSaveArchive). All errors are silently swallowed and the persistence value name is chosen to look like a Windows update task, hiding the behavior from the developer installing the package.
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-2026-11488?
Remove the package from your dependencies and lockfiles, then rotate any secrets on machines where it was installed.
