Authorities discovered a fraudulent scheme involving dozens of gas-station employees who installed malicious programs on electronic gas pumps to trick customers into paying for more fuel than they pumped into their vehicles. The scam shorted customers between 3-to 7 percent per gallon of gas pumped. Authorities arrested the hacker Denis Zayev on Saturday, charged with the creation of several programs designed for such kind of frauds. Authorities revealed that the programs were found only on gas stations in the south of the country. It has been estimated that the fraud allowed the hacker and employees to earn hundreds of millions of rubles.”]
