ATLANTA (AP) — A Russian man pleaded guilty to a conspiracy charge Tuesday after federal authorities say he created a computer program that has been used to drain bank accounts.

Aleksandr Andreevich Panin, who’s also known as “Gribodemon” and “Harderman,” pleaded guilty to a single count of conspiracy to commit bank fraud and wire fraud. He appeared in federal court wearing an orange jail uniform with his legs chained together as he entered a guilty plea after reaching a plea agreement with prosecutors.
