# MAL-2026-14244: Malicious code in gemini-cli-a2a-server (npm)


- **Type:** Malicious package
- **Package:** `gemini-cli-a2a-server` (npm)
- **Published:** 19 Aug 2026

## What is MAL-2026-14244?

MAL-2026-14244 is a malicious package in gemini-cli-a2a-server, published on 19 Aug 2026. 

### Official description

On npm install, the package's postinstall script collects host identifiers (os.hostname(), platform, arch, Node version, and package/lifecycle metadata) and POSTs them via https.request to the hardcoded endpoint https://onpx9s3x.instances.poc.jchunt.top/gemini-cli-a2a-server. The package name mimics a private Google Gemini CLI a2a-server component, and a source.txt reference in the tarball points at that internal package — consistent with a dependency-confusion probe that pings out from any environment that inadvertently resolves this public name instead of the intended private one.

## What should I do about MAL-2026-14244?

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