Russian Slot Mafia
An interesting read:
Russia has been a hotbed of slots-related malfeasance since 2009, when the country outlawed virtually all gambling. (Vladimir Putin, who was prime minister at the time, reportedly believed the move would reduce the power of Georgian organized crime.) The ban forced thousands of casinos to sell their slot machines at steep discounts to whatever customers they could find. Some of those cut-rate slots wound up in the hands of counterfeiters eager to learn how to load new games onto old circuit boards. Others apparently went to Murat Bliev’s bosses in St. Petersburg, who were keen to probe the machines’ source code for vulnerabilities.
