Malaysia arrests 'terrorist hacker' linked to Abu Hussain al-Britani

Malaysian police have arrested a Kosovo citizen wanted by Washington for allegedly stealing data related to more than a thousand US military and government personnel and providing the information to the Islamic State group [IS, formerly ISIS].

In a statement late Thursday, Malaysian police said the 20-year-old man was arrested on September 15 and that he had arrived in the Southeast Asian country last year to study computer science in a private university.

The US Department of Justice said in a statement on Thursday it was seeking the extradition of the man, which it identified as Kosovo citizen Ardit Ferizi, known by his hacking moniker "Th3Dir3ctorY".

"This case is a first of its kind and, with these charges, we seek to hold Ferizi accountable for his theft of this information and his role in IS' targeting of US government employees," the statement quoted Assistant Attorney General John P. Carlin saying.

The justice department statement dubbed Ferizi "a terrorist hacker," saying he had submitted hacked data to an IS member who then posted a 30-page document on twitter containing "the names, e-mail addresses, e-mail passwords, locations and phone numbers for approximately 1,351 US military and other government personnel."

Between June and August 2015, Ferizi allegedly provided the information to IS member Junaid Hussain, also known as Abu Hussain al-Britani.

The twitter message read: "NEW: US Military AND Government HACKED by the Islamic State Hacking Division!"

"We are in your emails and computer systems, watching and recording your every move, we have your names and addresses, we are in your emails and social media accounts, we are extracting confidential data and passing on your personal information to the soldiers of the [caliphate], who soon with the permission of Allah will strike at your necks in your own lands!" the document said, according to the justice department.

The statement added that the document was meant for IS supporters in the US and elsewhere to use the data "belonging to the listed government employees for the purpose of encouraging terrorist attacks against those individuals."

If found guilty in the US, the hacker will face up to 35 years in jail.

Over the past year, Malaysian police have arrested numerous suspects whom they say were IS sympathisers plotting attacks in the country.

Malaysia's senior counter-terrorism official Ayob Khan Mydin Pitchay said in June that authorities had so far arrested 108 people who had suspected links to IS or were trying to travel to Syria or Iraq.

Muslim-majority Malaysia has not seen any notable terror attacks in recent years.

But concern has risen in the multi-faith nation over growing hardline Islamic views and the country's potential as a militant breeding ground.
