Security researchers have uncovered the command and control network of a Zeus 2 botnet sub-system targeted at UK surfers that controlled an estimated 100,000 computers.
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.
