Group of hackers, four Russians and a Ukrainian allegedly broke computer networks of more than a dozen major American and international corporations. They allegedly stole 160 million credit card numbers over the course of seven years. The group would then allegedly install “sniffers” within the networks to automatically obtain electronic data from tens of thousands of credit cards. After stealing data, they sold it to resellers, who then sold it through online forums or to individuals and organizations. The defendants were identified as Russian Vladimir Drinkman, Aleksander Kalinin, Roman Kotov and Dmitriy Smilianets.
