autobahn-electron-probe @99.99.3

Summary

package.json declares preinstall and postinstall lifecycle scripts that run curl against http://da9ohqqvbsgu1166tuu0rrroxsztr18dt.cyowl.com/autobahn-electron-probe/, sending the installer's username (whoami), hostname, current working directory, and a timestamp as query parameters over plain HTTP. The long unique subdomain under cyowl.com is a DNS-callback / OAST-style exfiltration pattern. The scripts fire automatically on npm install without any user action, and the package ships no functional module code — the lifecycle beacon is the entire payload. The package name resembles the Autobahn WebSocket project and Electron, but the shipped contents perform only host reconnaissance and beaconing.
