International police did not name specific victims. The crooks were able to steal about $100 million in cryptocurrency as well as personal data.

The exact circumstances remain shrouded in mystery.

The attacks were anything but unique. Still, they worked.

The move comes after hackers infiltrated Twitter CEO Jack Dorey's account.

They also threatened victims' families, according to an indictment.

The six men were paying off mobile phone customer service representatives for access to victim's phone numbers.
