On June 16, 2011, a WikiLeaks associate named "q" contacted "Topiary," the nickname of Scottish hacker and LulzSec member Jake Davis who was charged and released on bail last year, in an Internet Relay Chat channel. Topiary was skeptical at first, thinking it was either a joker or a troll. But he was convinced when Assange posted a video on YouTube in real time of the chat they were having. The camera panned and revealed the WikiLeaks founder staring into the laptop.
Along with Assange, Topiary, and "q" in the chat was Sabu, the founder of LulzSec, who by now was also working as an informant for the FBI after being arrested on June 7.
q said he wished WikiLeaks could help the group more with things like servers or even advice, but they didn't want to link the organization too obviously to LulzSec.
