LulzSec uncovered: are these the names and roles of the members?

The group behind LulzSec has never made its intentions clear – apart from a website which proclaims that "we have now taken it upon ourselves to spread fun, fun, fun, throughout the entire calender [sic] year." However Tal Be'ery, lead web researcher at Imperva , has put together a profile of LulzSec based on their own work, plus some information that is publicly available. • LulzSec seems to be a spin-off of a group of hackers from the "Anonymous" organisation. • They hacked HBgary and Gawker under the umbrella of the Anonymous group, but then decided to create their own "gig". Why? Probably to be independent. • The supporting evidence for that is that the same nicks [nicknames] are used on both anonymous hacking-related discussions (early 2011) and LulzSec (mid 2011). • They communicate mainly via private IRC channels – and publish via Twitter and Pastebin . • They mostly use web application vulnerabilities: they used SQL injection to hack PBS and (one of) the Sony hacks (against Sony Pictures). • They also use automated tools to harvest databases, called Havij , as we can see from the leaked PBS hack screenshots. The group is small – less than 10 or so. (This is confirmed separately by security researcher Rik Ferguson of Trend Micro, who comments that "it seems to be a tight-knit group – it only needs to be a few people, since all they need is a Twitter account and a web page. There's no evidence that they're a particularly sophisticated group.) The members, according to Imperva: • "Sabu" – HBgary hacker. Seems to be the leader. • "Nakomis" – Coder, rumoured to be one of coders of the PHPBB bulletin board. • "Topiary" – handles finance, such as donations and payment for services (eg botnets) • "Tflow" – Hacker. (Rumoured.) • "Kayla" – Hacker. Owns a big botnet . • "Joepie91" – Website admin. • "Avunit" - No more detail. From hacker discussion forums, it seems they might get arrested as soon as many "real world" details on their identities get revealed, suggests Tal Be'ery.
