Summary
Malicious code in react-puller (npm)
Details

-= Per source details. Do not edit below this line.=-

Source: amazon-inspector (a3ac07c0f6c79714a7b1f6bfd1272f9f7942cf0473875ca5276a1034c084f06d)

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.
