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, and was at one point suspected of being the infamous executioner "Jihadi John".
