Today, we will examine HTTPS activity from a Dridex malware infection.

With this key log file, we can decrypt HTTPS activity in a pcap and review its contents. Decryption is possible with a text-based log containing encryption key data captured when the pcap was originally recorded. This Wireshark tutorial describes how to decrypt HTTPS traffic from a pcap in Wireshark.

When reviewing pcaps from malware activity, it’s very helpful to know what’s contained within post-infection traffic. But like most websites, various types of malware also use HTTPS. Why? Because most websites use the Hypertext Transfer Protocol Secure (HTTPS) protocol.

When reviewing suspicious network activity, we often run across encrypted traffic. The instructions assume you are familiar with Wireshark, and it focuses on Wireshark version 3.x. Udp.port = 5060 || tcp.This tutorial is designed for security professionals who investigate suspicious network activity and review packet captures (pcaps) of the traffic. You can use the following operators to check conditions: Operator In this article, we’ll only focus on display filters that can help you find specific traffic quickly.įilters are set at the top of the Wireshark window in the Apply a display filter field.Ī Wireshark filter is a string where you can specify various filtering conditions. There are two types of Wireshark filters: display filters and capture filters. In this article, we have collected basic examples of Wireshark filters (by IP address, protocol, port, MAC address, etc.), which will be useful for a quick start. For novice administrators, applying filters in Wireshark raises a number of questions. For the convenience of filtering all traffic passing through the network card, you can use Wireshark filters. Wireshark is a popular network traffic analysis tool that can be used to diagnose network connections and detect the activity of various programs and protocols.
