TCP Stream which shows communication between IP addresses in more There is still a lot of traffic generated, consequently we have toĪnother extremely useful wireshark option we used, was Analyze → Follow In spite of the filter above it helps a lot, yet Where this filter will narrow down the results that are presented into GET, we should use the following filter: = “GET”. To be able to filter only the http protocols on port 80 with a header Potential threat for the organization and personal use with a different User generated and has been visiting different source, where can be Through each generated http protocol traffic we can conclude that the Rules, which will help and guide for better and easy analysis. Therefore we have to apply and additional filter However, from the figure 1 we can see that there is a lot of traffic
Illustration 1: Wireshark application, filter: http protocol On figureġ it shows the Graphic Interface of Wireshark application with running Useful links for future use, please refer to.
Therefore please refer to the following link: Where the main goal and purpose for wiresharkĪpplication is to analysis a network protocols from captured file.

Select the stream and press Ctrl + h or you can use File->Export Packet Bytes. Go down a bit and bingo, you can find the PNG image’s header! 😉 Load up the challenge file and try to find the packets having length greater than 1000 bytes. Let’s repeat the same steps to find what was transferred. Also I found the file names that were present inside the flash drive. So as a conclusion check for the packets having size greater than 1000 bytes with flags URB_BULK out/in. Most of the packet’s sizes were less than 100 bytes and the transferred text file was found in a packet having a length greater than 1000 bytes, check the URB_BULK out. To capture the USB traffic you must load the USB kernel module ( check here). Of course, wireshark was listening to the usb interface in the background.
I plugged in a USB device and transferred a text file ( with contents “findme”*1000).
I made a simple test to understand how a simple file is transferred via USB protocol. Wireshark doesn’t have an easy option to view the transferred files using USB protocol, on the contrary it’s easy to extract or view transferred files in TCP (using TCP stream). In the following paragraphs I will try to explain my approach to solve this problem but i f you just want to see the solution please check the last 2 paragraphs. The initial 4 packets had the information of the devices involved in the traffic. Using the Product ID and Vendor ID I did some research here to get the device details. In fact, this is my first attempt to recover USB traffic from a PCAP file.
