MoneyGram International

Russian computer hackers operating in Colorado and 15 other states used data-mining viruses to steal thousands of credit card numbers from U.S. residents in 20 states

They sold them on the darknet for more than $3.6 million.

Criminals use software to access hidden websites and blogs on the darknet so they can operate anonymously.

A web of conspirators in Colorado and 15 other states funneled money back to accounts set up in the Russian Federation.
