The company said they would provide a month of “free access” to users and compensate customers who were forced to cancel their credit cards.

Darrell Foxworth, a special agent with the FBI in San Diego, said cyber-crime is a federal offense.

Foxworth said anyone with information or concerns visit the FBI’s internet crime complaint center.
