Using the motto "Laughing at your security since 2011!", LulzSec – short for Lulz Security – spent several months of their time embarrassing several companies by basically exposing poor online security.
These weren’t just any companies, however – LulzSec chose big names, such as Fox News, The X Factor, and Sony. Using comparatively basic attacks (such as SQL injection, the technique that they used against Sony’s PlayStation Network and a constant threat which the major electronics giant should certainly have been aware of) they were able to take down major websites, later claiming responsibility. The idea was to raise awareness of the lax security measures in place by bodies that should know better, although there was also an element of revenge involved; for instance, the Sony attack was in retaliation for the company’s pursuit of George Holz and his cracking of the PS3 DRM.
In the background, LulzSec is believed to be a handful of individuals with scripting and hacking skills and a possible previous affiliation with the Anonymous group who have been involved in various “hackitvism” campaigns over the past few years such as the 2011 leak of damaging documents purported to be from Bank of America.
Ultimately, LulzSec claim that they do what they do for fun: “for the lulz”. “Lulz” is a variation of the term LOLs, derived from the text speak alternative for the phrase “laugh out loud”.
