Junaid Hussain

Junaid Hussain (Arabic: جنید حسین‎‎, c. 1994 – 25 August 2015) was a British-Pakistani black hat hacker and propagandist under the nom de guerre of Abu Hussain al-Britani who supported the Islamic State of Iraq and the Levant (ISIL). Hussain, who grew up in Birmingham in a Pakistani-origin family, was jailed in 2012 for hacking Tony Blair's accounts and posting his personal information online. Hussain left the UK around 2013 for Syria. Sporadic reports surfaced from British media in 2014 speculating that Hussein could have been the infamous British executioner Mohamed Emwazi, then only known as his tabloid nickname "Jihadi John".

Hussain was known as TriCk from the disbanded hacking group TeaMp0isoN. He was a key figure in a group of Islamist computer hackers who call themselves the Cyber Caliphate. The Islamist hackers have been involved in defacing French websites during the 2015 Île-de-France attacks and the Twitter feeds of the U.S. Central Command, Newsweek and the International Business Times. The group is believed to be behind the use of a spearphishing attack that exposed identities of rebel media groups.

Hussain was in online contact with one of the gunmen behind the Curtis Culwell Center attack of May 2015. Before the incident, an attacker posted online statements on Twitter, in which he requested others to follow Hussain's account. After the shooting occurred, Hussain wrote: "Allahu Akbar!!!! 2 of our brothers just opened fire."
