What is MAL-2026-11144?
MAL-2026-11144 is a malicious package in react-puller, published on 28 Jul 2026.
Official description
The package's postinstall hook runs
node index.js, which spawns a detached worker that downloads two Windows executables (CDPUserPlatform.exe and DOContentCacheMgr.exe) from a hardcoded bare-IP endpoint at http://64.49.11.161:8000 over plain HTTP, writes them into ~/.react-pul, and launches them via cmd /c start. The addToStartup routine then writes an HKCU\Software\Microsoft\Windows\CurrentVersion\Run entry pointing at ~/.react-pul/DOContentCacheMgr.exe, autostarting the dropped binary on every user login. The package name and description present it as a generic React utility, unrelated to the shipped behavior.What should I do about MAL-2026-11144?
Remove the package from your dependencies and lockfiles, then rotate any secrets on machines where it was installed.
