Cyberspace Solarium Commission Report

The Cyberspace Solarium Report released today is another, in an endless string of reports, that disgorge from Washington committees dealing with the eternal mantra of "defending American interests and values in cyberspace."

We hypothesized that countries with more transparent, democratic governmental institutions would harbor a smaller fraction of misbehaving (blacklisted) hosts. The available data confirms this hypothesis. A similar correlation exists between perceived corruption and fraction of blacklisted IP addresses. more

While most malware-generated traffic passing through most channels used for communicating with botnets (such as TCP, IRC, HTTP or Twitter feeds and Facebook walls) can be detected and blocked, it's not the case for DNS (Domain Name System) and attackers are taking advantage of that, said Ed Skoudis, founder of Counter Hack Challenges and SANS fellow. more
