Windows 7: 70 percent of exploit kits come from Russia, says report

Almost 60 percent of vulnerabilities in computing systems used by exploit kits are over two years old, and the majority of exploit kit development takes place in Russia, according to a new study by Solutionary's Security Engineering Research Team (SERT).

The research paper (reg. required) says that out of 26 exploit kits analyzed by SERT, 70 percent were either released or created in Russia, with China and Brazil the other most popular regions for exploit kit development.

SERT's report also suggests that despite a number of high-profile DDoS attacks -- including hits on financial institutions, Wikileaks and Demonoid -- in Q4 2012, there was a slight reduction in reported attacks. Authentication security attacks and the presence of malware increased.
