Idea

If you get access to a PCAP file, for example during a CTF or captured on your own, you usually have the problem of overlooking all the relevant information to get a basic idea of the capture file. This gets worse if the capture file includes lots of white noise or irrelevant traffic - often included in the capture file to cloak interesting packets in a bunch of packets to YouTube, Reddit, Twitter and others.

pancap addresses this problem. With multiple submodules, it analyzes the given PCAP file and extracts useful information out of it. In many cases, this saves you a lot of time and can point you into the right direction.

Usage

Simply run

go get github.com/maride/pancap

This will also build pancap and place it into your GOBIN directory - means you can directly execute it!

In any use case, you need to specify the file you want to analyze, simply handed over to pancap with the -file flag.

Example usage:

pancap -file ~/Schreibtisch/mitschnitt.pcapng

This will give you a result similar to this:

asciicast

Contributions

... yes please! There are still a lot of modules missing. If you are brave enough, you can even implement another Link Type. Pancap currently only supports Ethernet (which, to be honest, fits most cases well), but USB might be interesting, too. Especially sniffed keyboard and mouse packets are hard to analyze by hand...
