## What is MAL-2026-15501?

MAL-2026-15501 is a malicious package in grafeno-api, published on 28 Aug 2026. 

### Official description

package.json declares a preinstall script that shells out via child_process to curl http://216.126.236.46/x.sh and pipe the response into /bin/bash, running attacker-controlled code on the installer's machine at npm install time. The fetch is unpinned, uses plain HTTP to a bare IP with no integrity check, and is wrapped in a try/catch that suppresses errors. The shipped index.js is a one-line stub exporting a no-op request() function, so the package provides no legitimate functionality — the manifest lifecycle hook is the entire payload, and the 'API client' framing is a cover story.
