Some thoughts about the future
With the introduction of IP Version 6 getting closer and closer, the classical search, find and compromise tactics will surely fade away. Thus attackers will shift to more client side exploitation in order to compromise new machines. With this trend services like email, DNS servers, and network routing infrastructure will be the number one targets in the future. For this reason i expect SPAM to increase as it is the easiest way to reach new victims without much effort. Vulnerabilities in email clients or malicious attachments are already increasing in todays email traffic.
As IPv6 heavily relies on a working DNS infrastructure, attacks on DNS servers will increase as well. An attacker who controls a DNS server controls all clients using this server. With the help of compromised DNS servers attackers can direct victims to prepared websites exploiting vulnerabilities in browsers or harvest user credentials with the help of phishing sites. With the compromise of network infrastructure such as switches or routers things will even get worse. Thus it is of interest to develop tools to detect, monitor and understand attacks on DNS and network infrastructure as well as find a solution for the ever increasing SPAM messages filling the inboxes.
