Angelo Martino's job at DigitalMint in River North was to negotiate on behalf of companies whose computers were hacked and held, with demands to make multimillion-dollar ransom payments.
However, the U.S. Department of Justice says Martino actually helped the hackers he was hired to negotiate against.
The victim clients included hospitality, retail, medical and financial services businesses.
Overall, Martino and his associates extorted more than $75-million.
Martino has been sentenced to nearly six years in prison, with how much he'll pay in restitution to be determined.
