# MAL-2026-16149: Malicious code in os-info-meeb322k (npm)


- **Type:** Malicious package
- **Package:** `os-info-meeb322k` (npm)
- **Published:** 14 Sep 2026

## What is MAL-2026-16149?

MAL-2026-16149 is a malicious package in os-info-meeb322k, published on 14 Sep 2026. 

### Official description

The package's postinstall lifecycle script runs unconditionally on npm install. It collects host identifiers (hostname, platform, architecture, kernel release, uid/gid, CPU count, memory) and internal network interface addresses, base64-encodes the payload, and POSTs it over plain HTTP to the hardcoded subdomain vml73pdk3ft3t434ssjycv4khbn2btzi.oastify.com — a Burp Collaborator (OAST) callback host used to confirm code execution on the installer. The package has no other functionality; its sole install-time effect is the outbound beacon carrying installer reconnaissance data to an attacker-controlled domain.

## What should I do about MAL-2026-16149?

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