The FBI yesterday pulled off a major coup when it went public claiming that a key figure of the LulzSec hacktivist group — Hector Monsegur, know as ‘Sabu’ — had been working for the organisation to help bring down the group.

The FBI says it pushed Sabu into cooperating after he had been identified online, however evidence suggests that he was not entirely focused on helping US authorities, as he was still assisting with hacking exploits.

According a Pastebin posting that details a conversation between Sabu and ‘Havittaja‘, a hacker associated with LulzSec and Anonymous, Sabu was continuing to support the efforts by supplying passwords and website data as recently January. That’s some way after August, when the FBI says Sabu first began cooperating after he pleaded guilty to 12 charges of hacking-related offenses.

The recruitment of Sabu was said to be “devastating to the organization” and akin to ““chopping off the head of LulzSec”. Working with Sabu, who is said to have opted to work as an informant rather than risk lengthy time in prison, the FBI was able to capture five high-level figures from LulzSec.

However, a tweet from Havittaja even claims that Sabu had a hand in its most recent attack:

Sabu himself took to Twitter this week after news of his defection went public. His earlier tweets claimed that authorities were searching his property, listening in to his calls and keeping him closely under surveillance:

Either way, figures within Anonymous — Havittaja included — have turned their back on Sabu for assisting the state, suggesting that his time assisting them is over. And for the FBI, the cheers for hooking a bad guy may not ring so loudly if it is indeed true that he was continuing to help set up more hacks.

It’s worth saying that the exact details of Sabu’s assistance with the FBI are unknown, while the alleged continuation of his work with LulzSec and Anonymous  would give him cover to ensure he was not exposed for snitching on the organisation. Nonetheless, it is fascinating to consider that he may have been both problem solver and problem creator for the FBI at the same time.
