# MAL-2026-11528: Malicious code in @ks-openclaw/kim (npm)


- **Type:** Malicious package
- **Package:** `@ks-openclaw/kim` (npm)
- **Published:** 4 Aug 2026

## What is MAL-2026-11528?

MAL-2026-11528 is a malicious package in @ks-openclaw/kim, published on 4 Aug 2026. 

### Official description

The package's preinstall lifecycle script (preinstall.js) opens a TCP socket to the hardcoded remote host 120.55.170.103:8888, spawns cmd.exe, and pipes the shell's stdio through the socket, giving the remote party full interactive command execution on the installer's machine during `npm install`. The same script also collects installer host identifiers (os.hostname(), os.userInfo().username, os.platform(), process.version, process.cwd()) while the reverse shell is connected. Cover-story strings in the file ("Proof of Concept", "Dependency Confusion") do not change the observed behavior: install-time remote code execution against the installer.

## What should I do about MAL-2026-11528?

Remove the package from your dependencies and lockfiles, then rotate any secrets on machines where it was installed.
