One of the more powerful techniques for network hunting is sifting through a network capture. In this post, we will be looking at how to identify the connections with the most packets, how to enable DNS resolution in the captures, and how to create a series of basic filters to remove known “good” traffic from the packet capture.

iPhone then stores DAN into a special hardware chip. Bank returns a token called DAN (device account number) to the iPhone. To understand the difference, we break down the process into two flows.ġ️⃣ The registration flow is represented by steps 1~3 for both cases. Both approaches are very secure, but the implementations are different. How do Apple Pay and Google Pay handle sensitive card info?
