Purple Shark – A Bash Script For PCAP Analysis – Cyber Security

Today, Dante’s Derivatives will show you a bash script that you can use to automatically analyze PCAP files. PCAP’s are packet capture files that can show valuable network traffic information. The Blue Team Cyber Security industry relies heavily on viewing PCAP files to answer questions about what happened to a network. Sometimes these PCAP files can be massive, and finding information in these files can therefore be difficult. My team and I wanted to create a bash script that could automatically read through a PCAP file of any length and extract valuable information that an expert could use without having to open Wireshark.

The entire Purple Shark program is 120 lines of code and 100% bash scripting. Purple Shark also utilizes some zenity code to act as a graphic user interface for user’s to interact with while using Purple Shark to analyze their PCAP files.
