Starting on April 30, the Linux operating system Ubuntu experienced DDoS (Distributed Denial-of-Service) attacks, preventing users from being able to update and install Ubuntu. A group of hacktivists, dubbed The Islamic Cyber Resistance, claimed that they were responsible for the DDoS attack through the use of Beamed, a DDoS for-hire service, whose attacks can reach 3.5 Terabits per second. This service allows anyone to pay for the launch of DDoS attacks, regardless of their technical skills, and is a service which authorities like the FBI must consistently take down.
