CWmike writes "Criminal cybergangs must be harried, hounded and hunted until they're driven out of business, a noted botnet researcher said as he prepared to pitch a new anti-malware strategy at the RSA Conference in SF. 'We need a new approach to fighting cybercrime,' said Joe Stewart, director of SecureWorks' counterthreat unit. 'What we're doing now is not making a significant dent.' He said teams of paid security researchers should set up like a police department's major crimes unit or a military special operations team, perhaps infiltrating the botnet group and employing a spectrum of disruptive tactics. Stewart cited last November's takedown of McColo as one success story. Another is the Conficker Working Group. 'Criminals are operating with the same risk-effort-reward model of legitimate businesses,' said Stewart. 'If we really want to dissuade them, we have to attack all three of those. Only then can we disrupt their business.'"
