A teen coder and his team developed a new malware named Silex that purposely bricked poorly protected IoT devices by the thousands in a short period of time. The attacks have stopped as the command and control (C2) server went down around 4 PM Eastern Time, by the developer’s doing. The malware was created by a team of three, with the main person being a teenager from a European country using the aliases ‘Light The Leafon’ and ‘Light the Sylveon’ The main person is the author of another bot called HITO, which was based off another IoT malware named Mirai.
