According to the indictment, Bary used bitcoin to buy stolen payment card information on the dark web, which the group then used to defraud banks.
On one of his mobile phones, police found photographs of dozens of bank cards and screen shots of instructions for how to use customer data to create false credit card identities.
It is not clear how much money the group had defrauded in total.
Among the photographs stored on his phone, Bary had three entry visas for Sudan under Syrian names. When he was arrested, he claimed to be a Syrian national called Ahmed Mohamed Al Oulabi.
Bary’s father is Egyptian Islamic extremist Adel Abdul Bary, who was extradited to the US and jailed for his role in the 1998 terror attacks on the US embassies in Kenya and Tanzania that claimed 123 lives.
