A hacker purporting to represent the group LulzSec has claimed responsibility for a DDoS attack that affected UK telecom TalkTalk this week. If you remember, LulzSec was a hacking team from 2011 which hacked targets for ‘Lulz’ Here is a brief bio on them : Lulz Security, commonly abbreviated as LulzSec claimed responsibility for several high profile attacks, including the compromise of user accounts from Sony Pictures in 2011. The group had also hacked CIA website during that time and taken it offline. Some security professionals have commented that LulzSec has drawn attention to insecure systems and the dangers of password reuse. It has gained attention due to its high profile targets and the sarcastic messages it has posted in the aftermath of its attacks. One of the founders of LulzSec was a computer security specialist who used the online moniker Sabu who later helped FBI track down many hackers belonging to LulzSec and Anonymous. At least four associates of LulzSec were arrested in March 2012 as part of this investigation. British authorities had previously announced the arrests of two teenagers they allege are LulzSec members T-flow and Topiary. TalkTalk was hacked on Thursday by unknown hackers who demanded ransom money for stolen user information. Now, hackers claiming to be part of LulzSec have claimed responsibility for part of the attack. A hacker who goes by the name AnonZor, who claims to be member of the revived LulzSec, told Motherboard they and co-leader Dax took down the website with a DDoS attack, which works by flooding the target’s system with traffic. AnonZor added that LulzSec is not responsible for the leaked information or extortion revealed on Friday, only the DDoS attack. “The stolen data is not done by us, we only did a DDoS attack to show the world that #LulzSec has returned,” AnonZor said. AnonZor, who declined to reveal where the LulzSec hackers are located, said to expect more downtime from the site as attacks continue this weekend. Meanwhile TalkTalk share price went on downward spiral as more and more news about the hack attack is being published. Reports indicate that it will also have to pay out millions to the affected parties in damages.
