Authorities have arrested a Malaysia-based hacker who they accuse of stealing personal information of U.S. military members and giving it to ISIS.<br />Ardit Ferizi, a Kosovo citizen, was detained in Malaysia on a provisional U.S. arrest warrant alleging he provided material support to ISIS and committed computer hacking and identity theft, the U.S. Justice Department said.<br />U.S. Assistant Attorney General John Carlin called the case against Ferizi - which combines cybercrime and terror charges as U.S. authorities aim to step up their crackdown on ISIS - "a first of its kind."<br />The criminal complaint alleges there's probable cause to believe Ferizi hacked into a server and stole names and personally identifiable information of more than 1,300 U.S. military and other government personnel - a list that was later posted online in August by a group calling itself the "Islamic State Hacking Division."
