Threat Identification Using Active DNS Measurements

The third publication for the TIDE project. Details more formally the research questions of this project. The DNS is a core service for the Internet. Most uses of the DNS are benign, but some are malicious. Attackers often use a DNS do- main to enable an attack (e.g. DDoS attacks). Detection of these attacks often happens passively, but this leads to a reactive detection of attacks. However, registering and configuring a domain takes time.

Differently from regular spam, snowshoe spammers distribute the volume among many hosts, in order to make detection harder. To be successful, however spammers need to appear as legitimate as possible, for example, by adopting email best practice like Sender Policy Framework (SPF).
