A notorious hacker once nicknamed 'Anarchaos' and his identical twin brother, both of whom have done serious federal and state prison time, are allegedly leading an Antifa terror cell in Chicago ramping up violent protests against ICE, sources told Daily Mail.

Jeremy and Jason Hammond, 40, who have rap sheets going back 15 years, were both detained at an anti-ICE protest at a facility in Broadview, Illinois, on September 26 – just four days after President Trump signed an executive order designating Antifa as a domestic terrorist organization.

Three conservative activists on the ground in Chicago as well as law enforcement sources said the Hammonds have been front and center at recent anti-ICE protests in the Chicago area, and have been actively doxxing those fighting against leftist school boards and illegal immigration and for the police since 2020.

Jeremy Hammond refers to such action as 'anti-fash' crusades. 

Jeremy, who was once called the 'world's greatest computer hacker,' was first jailed over hacking into the right-wing Protest Warrior group in 2005 and was later convicted of computer fraud in 2013 for hacking the private intelligence form Stratfor and giving the data to Wikileaks. 

He was sentenced to 10 years in prison and released in November 2020.

Rolling Stone called him a 'legendary hacker and radical anarchist' that the FBI was determined to take down 'by any means necessary' in a 2012 profile.

His brother Jason was also arrested in 2013 for his part in a brutal attack on a restaurant in Tinley Park, Illinois. 

Police said at the time that Jason was among 18 masked men who stormed the restaurant and attacked diners having lunch – some of whom they believed to be white supremacists – with bats, clubs, and hammers. Ten people were injured.

In January 2015, Jason was sentenced to 41 months in state prison.
