Malware Increasingly Uses DNS As Command and Control Channel to Avoid Detection

Number of malware threats that receive instructions from attackers through DNS is expected to increase, and most companies are not currently scanning for such activity on their networks, security experts said at the RSA Conference 2012 on Tuesday. 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.
