Techopedia Explains LulzSec (Lulsec)

LulzSec is thought to be an offshoot of Anonymous, whose goals include avenging WikiLeaks and its founder Julian Assange, as well as promoting their own belief about what constitutes Internet freedom. LulzSec members have enlisted denial-of-service attacks, which cause specific computer users to be denied their authorized access to computer information, while the attackers flood the targeted servers. Other LulzSec attacks have taken the form of SQL injections, which involve using a code injection uncovering vulnerabilities within computer systems after a hacker processes worthless information, thus exploiting computer bugs.

Computer break-ins have been conducted by LulzSec against large organizations such as Sony, the U.S. Senate, AT&T among others. LulzSec took responsibility for crashing the CIA’s public website in June of 2011. This allegedly occurred after a Twitter follower dared LulzSec to prove their cyber prowess by hacking into FBI or CIA websites. Given the group’s claim of responsibility for the CIA attack, it appears that LulzSec members are willing to cross over from hacktivism to hacking on a dare. Public statements made by LulzSec members in June 2011 said they are hacking just because they know how to do it.
