## What is MAL-2026-16234?

MAL-2026-16234 is a malicious package in strapi-plugin-os-rec, published on 16 Sep 2026. 

### Official description

postinstall.js runs automatically on npm install and collects host reconnaissance data — os.hostname(), os.platform(), os.arch(), os.type(), os.release(), the current username, and enumeration of all network interface addresses — then transmits them as query-string parameters in an HTTP GET to hardcoded host 8y70jt07jkewju8wh0o1cgkaw12sqje8.oastify.com on port 80 at path /osinfo. The oastify.com subdomain is a Burp Collaborator out-of-band interaction endpoint used to receive reconnaissance beacons. The behavior is undocumented, fires on default install with no user interaction, and identifies the installing machine to an attacker-controlled listener.

## What should I do about MAL-2026-16234?

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