Official description
[email protected] declares a package.json postinstall script
wscript.exe Kelimasow.exe that auto-executes a bundled 8.4 MB Go-compiled Windows PE (Kelimasow.exe, sha256 875c7641dc980538f3c3d8b344d173f97cf64a5d97dcf88d8e2932c83b876b92) on npm install. The package has no README, empty description and author fields, no source code, and no other functional content — the manifest is a thin wrapper whose sole install-time effect is to execute an opaque native binary on the installer's machine. Opaque binary + lifecycle-hook auto-execution + missing metadata is the canonical install-time RCE / dropper packaging shape, giving whoever published this arbitrary code execution on any Windows host that installs the package.What should I do about MAL-2026-17295?
Remove the package from your dependencies and lockfiles, then rotate any secrets on machines where it was installed.
