NetworkWorld: On March 9, Microsoft issued a warning about an Internet Explorer bug that was being used for "targeted exploits." Now, two different cybergangs appear to have stepped up attacks related to the vulnerability. One group is installing fake anti-virus software on victims' computers, and the other is installing a variation on the Sinowal Trojan.
According to Roger Thompson of security vendor AVG, the company is receiving reports of up to 30,000 attacks per day. "It's not a massive attack, but it's an unpatched exploit being used aggressively," he said.
