A Russian national accused by U.S. federal prosecutors of developing an application for decrypting login credentials pleaded not guilty during a first appearance in Tampa federal court.

The man, Dariy Pankov – also known as “dpxaker” – faces seven criminal counts including conspiracy, access device fraud and computer fraud. On Wednesday in the courthouse for the U.S. District of the Middle District of Florida, Pankov said through a translator that he is fighting the prosecutors’ case. If found guilty on all counts, Pankov faces up to 47 years in prison.
