About the training

DNS is one of the basic layers that holds the internet together. Without it, not much else works... not even malware. In this training course 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.

Training focuses on the use of DNS for malware hunting, detection of new infrastructure, discovery of new network assets and other “research” type products. There is an emphasis on hands-on labs while also covering some theory and history of DNS. Multiple topics are available and can be tailored to the class based on their interest.

Key takeaways

• DNS for malware hunting
• Learn about all the resources you can use for DNS analysis
• Discover malicious activity through DNS data
