The Internet can be a scary place where anyone can be a victim at any time. But some may take comfort in knowing that certain hackers and black hat computer experts are focusing their attention on targets they think can afford to take a hit. McAfee and Guardian Analytics has identified a network of thieves who have stolen anywhere from %60-100 million so far, with attempts to steal much more. The campaign has been dubbed “Operation High Roller” and the targets are U.S. companies with at least several million dollars in their accounts.

The operation consists of at least 12 different groups. Specific targets are identified using online reconnaissance, but beyond that methods of infiltration vary. Amongst other exploits, the hackers are finding security flaws in automated transactions. As with most computer security issues, the attackers will always move quickly to expand their capabilities, challenging the defenders of computer security systems to keep up.
