A group of hacktivists have claimed responsibility for a distributed denial-of-service attack, which has affected several Ubuntu and Canonical websites, and prevented users from updating the Linux-based operating system.

The DDoS attack against Mastodon's flagship server comes less than a week after Bluesky was targeted with junk web traffic.

Europol coordinated an operation against for-hire distributed denial-of-service (DDoS) services, including the arrest of four people and the takedown of 53 domains.

An international law enforcement operation shut down a service called SocksEscort, which allegedly helped cybercriminals all over the world launch ransomware and DDoS attacks, as well as distribute child sexual abuse material.
