A Kosovan man has been arrested in Malaysia for allegedly hacking into a computer database and providing information on US security officials to the so-called Islamic State group.
The man, who is in his 20s, was detained on 15 September, Malaysian police said in a statement on Thursday.
Separately, the US identified him as Ardit Ferizi, thought to head a hacker group called Kosova Hacker's Security (KHS).
Mr Ferizi will be extradited to the US.
A statement from the US Department of Justice said Mr Ferizi, known by his moniker "Th3Dir3ctorY", hacked into a US company's systems in order to take the personal details of 1,351 US military and government staff.
He will be charged with computer hacking and identity theft, and faces up to 35 years in jail, the statement added.
