Such a file is either upfront given along with a pcap file that contains encrypted traffic or is obfuscated away in some other file left with clues to be found. The file basically enumerates the secret keys exchanged in the Diffie-Hellman, three way handshake done while establishing a secure channel for the underlying application protocol. A snippet of the contents of such a file is shown below: We all know encrypted traffic is secure and cannot be parsed as shown above without the availability of key exchange files.įor packet captures which involves protocols like HTTPs, WSS, SSH we need to necessarily have the key exchange files. The same can be found below as an example for the DNS query packet.Īs more and more protocols are coming in their encrypted variants, there is more and more possibility of encrypted traffic being intercepted and the need to analyze such traffic. The layer wise segments along with protocol specific extensions are parsed and rendered in an easy to view structure. Supported protocols and protocol specific reference can be found here.įor each frame/packet, the segments of the packet are shown clearly as per the protocol stack. An exhaustive reference for the same can be found here. The filter area is mainly used to apply a plethora of protocol specific filters that are available in Wireshark.

The major areas are explained in the image above. Any of the Wireshark supported formats can be opened using this method.īelow is the UI we see after opening any supported packet capture file: To use this, you can open the capture file from the File > Open menu of Wireshark. The mode we are concerned with, is analysis of packet capture files. But often, this mode is more useful for penetration testing a product and less during a CTF. This mode of wireshark is more useful for network based challenges where we need to intercept the traffic between our box and a challenge server. The initial screen shows the interfaces which are detected by wireshark, each of which can be configured to intercept packages. I will provide a high level overview of the UI here. The UI of Wireshark is intuitive and easy to get used to.

On Windows and MacOS the official website provides the required binaries for installation. This is the preferred Linux distro for pen-testing and other security usages. Most of the Kali Linux distributions already have Wireshark pre-installed in them.
