MAL-2026-13761 Malicious code in dakumangalsingh_virus (npm)

The tarball contains a 455 KB Windows PE64 executable named DakuMangalSingh.exe (sha256 368320791e5c022ffabedb44eae6ca902fe3f524754a085b726617c2006dc791) alongside a zero-byte index.js. package.json declares no preinstall/install/postinstall/prepare lifecycle scripts and its main entry is empty, so neither npm install nor require() of the package causes the binary to be executed, decoded, or written elsewhere. The package name self-labels as a virus, and no documentation, source, or purpose is provided for the shipped binary. Installing or importing this package in a normal npm pipeline does not run the executable; harm would only occur if a user were separately induced to launch DakuMangalSingh.exe on a Windows host.

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.
