How Sabu was outed by former Anons long before his arrest

When the FBI arrested LulzSec leader Hector "Sabu" Monsegur, they did so in a hurry—hours before the arrest, Sabu was doxed, his identity posted to the Internet. With his name public, federal agents feared that he would start destroying evidence to protect himself, so they ended their covert surveillance and moved in, according to Fox News.

Efforts to name and shame the LulzSec crew during its 50-day rampage were common. Many of these doxings were inaccurate, a result of faulty inferences or deliberate attempts to mislead on the part of the LulzSec hackers.

But not all were wrong. In fact, the game of doxing Sabu was over before it had even started. He was correctly doxed more than two months before his arrest—in fact, more than a month before LulzSec had even started publicly operating. This first doxing happened after a group of former Anonymous members, displeased at the moralizing direction that Anonymous had taken and at Sabu's leadership role, decided to take action. Speaking to Gawker almost one year ago, the dissident group calling itself Backtrace Security announced that it was going to post chat transcripts and information about the identies of Anonymous members.
