Trusteer researchers recently uncovered the command and control network of a botnet targeting UK users that controls approximately 100,000 PCs.

"Cybercrooks based in eastern Europe used a variant of the Zeus 2 cybercrime toolkit to harvest personal data -- including bank log-ins, credit and debit card numbers, bank statements, browser cookies, client side certificates, and log-in information for email accounts and social networks -- from compromised Windows systems," writes The Register's John Leyden.

"Trusteer researchers identified the botnet's drop servers and command and control centre before using reverse engineering to gain access its back-end database and user interface," Leyden writes. "A log of IP addresses used to access the system, presumably by the cybercrooks that controlled it, was passed by Trusteer onto the Metropolitan Police."
