According to media reports, a U.S. drone strike near Al-Raqqa, Syria on December 10, 2015, killed Bangladeshi-born ISIS hacker Siful Haque Sujan. Sujan was a top ISIS hacker who also coordinated counter-surveillance technology and weapons development.
Sujan (31) travelled to the U.K. to study in 2004 but was forced to leave the country in 2014 when he failed to receive a visa extension. Sujan was the replacement for Junaid Hussain, the top ISIS hacker who was killed in a drone strike in August.
