DNS Threat Intel

June 23, 2019 @ 9:00 am 5:00 pm


DNS is the one of the basic layers that holds the Internet together. Without it, not much else works… even malware. In this training we will focus on how to use DNS to the advantage of defending networks. With good techniques it is possible to find a great deal of misuse based on DNS such as DGAs, fast/double flux networks, phishing, and brand impersonation. Tools like passive DNS, whois, and active probing allow defenders to proactively search for malicious indicators before they are operationalized so defenders can get ahead of the attack cycle. This is a training on the usage of DNS for malware hunting, detection of new infrastructure, discovery of new network assets and other “research” type of products. In this training we will focus on hands on labs while covering also some theory and history of DNS.
