The others arrested include Ryan Ackroyd, aka, ‘Kayla’ of London, Jake Davis, aka, ‘Topiary’ of London and Jeremy Hammand, aka, ‘Anarchaos’ of Chicago.
It is understood the FBI infiltrated LulzSec when Monsegur was tracked down at his home in New York last year.
LulzSec, which is affiliated with Anonymous, undertook several high-profile cyber attacks against Sony, Nintendo, Fox.com and the US Senate last year.
After being arrested at his home in New York’s Lower East Side by the FBI, Monsegur began co-operating with the authorities, according to Fox News.
A case against the hackers, including the two from Ireland, is expected to be heard in the Southern District court of New York.
Last September, the FBI arrested 23-year-old Cody Kretsinger. Kretsinger, also known online as "recursion," was alleged to be part of an attack which used an SQL injection against Sony Pictures’ computer systems. He masked his IP address using a proxy server.
