April 12, 2012, 2:55 PM — Hector “Sabu” Monsegur, 28, who gained infamy and a temp job as an FBI informer during his stint as a leader of the anti-everything script-kid sabotage squad LulzSec last summer, failed to appear in court today due to what his lawyer called "security issues and physical threats."
Who threatened the strutting hacker-leading turncoat seriously enough to make him afraid of showing up at a heavily guarded Manhattan criminal courthouse on a charge of criminal impersonation?
NoMan – or, actually, the modern equivalent, Anonymous, the hacktivist group that gave birth to and then reabsorbed LulzSec last fall.
Federal agents rounded up most of the LulzSec'ers last summer, but continued pursuing them in the U.K. and United States until March, when the FBI nabbed the five remaining leaders, including its loudest voice, "Sabu."
On the same day federal agents revealed much of the evidence against LulzSec came directly from Sabu, who had been acting as an informant since being arrested in June, 2011 and then released under supervision to gather more evidence.
The trail that led feds to Sabu in the first place came largely from hackers and hacktivist groups offended by LulzSec's bragging, triumphalism, provocative choice of targets (U.S. Senate, CIA.gov) and refusal to acknowledge the accomplishments or abilities of hackers with more experience and (in their own estimation) far greater skills than LulzSec.
Those whose efforts to "dox" Sabu by posting evidence of his activities, home domains and servers included outspoken LulzSec foes TeaMp0isoN (Team Poison), lone hacktivists like th3j35t3r (The Jester) and WebNinjas.
Monsegur (Sabu) has been in hiding under house arrest or federal protection since the last rounds of LulzSec arrests.
The hearing Monsegur skipped today was to evaluate a criminal charge of impersonating a federal law enforcement officer on the same day the rest of the LulzSec leaders were arrested.
