Lizard Squad

Lizard Squad was a black hat hacking group, mainly known for their claims of distributed denial-of-service (DDoS) attacks primarily to disrupt gaming-related services.

On September 3, 2014, Lizard Squad seemingly announced that it had disbanded only to return later on, claiming responsibility for a variety of attacks on prominent websites. The organization at one point participated in the Darkode hacking forums and shared hosting with them.

On April 30, 2016, Cloudflare published a blogpost detailing how cyber criminals using this group's name were issuing random threats of carrying out DDoS attacks. Despite these threats, Cloudflare claim they failed to carry through with a single attack. As a result of this, the British National Fraud Intelligence Bureau issued an alert warning businesses not to comply with ransom messages threatening DDoS attacks.
