# MAL-2026-10632: Malicious code in cppt-common (npm)

## What is MAL-2026-10632?

MAL-2026-10632 is a malicious package in cppt-common, published on 14 Jul 2026. 

### Official description

cppt-common@13.1.1 declares a preinstall hook ("preinstall": "node index.js") that runs automatically on npm install. index.js collects host and user identifiers — os.hostname(), os.userInfo(), the output of `whoami` and `id` via child_process.exec, platform/arch/memory, cwd, homedir, and shell — and POSTs the collected JSON to a hardcoded endpoint at https://mj9yg25wm8m4vnkrrok8lwcogfm6awyl.oastify.com/detox56. The oastify.com host is a Burp Collaborator out-of-band callback domain used for exfiltration. The package has empty description and author fields and provides no advertised functionality; its only install-time effect is the reconnaissance beacon.

## What should I do about MAL-2026-10632?

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