Extracting files from network traffic is a common task. However, it isn't always as straight-forward as you may hope. In this video, we'll look at extracting a ZIP file from a PCAP. The ZIP file was a means of data exfiltration from some malware. We'll discuss how to extract the ZIP in Wireshark and NetworkMiner. We'll also discuss using CyberChef to convert the raw bytes from the network traffic, unzip the file and view the contents.

The extraction and the unzip functions, where is the difference? Is the extraction based on extracting application data bytes after separating delimiters, null/padding values etc from raw data? I mean when I run an Hex through extraction which is supposedly a PKZIP, it gives out doc files, so are there overlapping functionalities?

Hi Josh,

thanks for the video.

I'm new to Wireshark. I wonder how to extract a PDF file from a .PCAP file?

Cheers!
Michael
