In this article “The man named by the FBI as infamous hacktivist Sabu was undone by an embarrassing security blunder, it has emerged.

The alleged LulzSec kingpin eventually copped to a battery of hacking charges last August and was reported to have been “co-operating” with the FBI in the months leading up toyesterday’s arrests.

 Police locked onto Hector Xavier Monsegur, an unemployed 28-year-old from New York – allegedly LulzSec hacktivist supremo Sabu – after he apparently made the mistake of logging into an IRC chat server without using the Tor anonymisation service1.

According to Robert Graham of Errata Security Monsegur exposed his IP address, which allowed federal investigators to request records from ISPs and track down his location to a flat shared with his two sons on Manhattan’s Lower East Side.

“They caught him because just once, he logged onto IRC without going through Tor, revealing to the FBI his IP address,” Graham claims. “This reveals a little bit about the FBI, namely that they’ve infiltrated enough of the popular IRC relays to be able to get people’s IP addresses. We’ve always suspected they could, now we know.”
