# Searcher Tab

## What can I search for?

Using this tab you can perform a binary packet search for a specific packet or a whole packet set that cause an effect. Let’s suppose you’ve fuzzed and got a large packet dump that, when replayed, causes an effect on your CAN device / car. You now want to extract the relevant packet(s) out of that dump. Searcher tab to the rescue – Load the whole packet dump and let the analyzer routine guide you. Note: This first tries to search for 1 packet that causes an action. It this fails, the searcher tries to continously minimize the packet set.

## It doesn’t work!!1!

Don’t give up too fast, try the following things: - Set the packet gap to a lower value, you can even try 0 - Just try again and hope for better shuffling - Use another dump/fuzz again, … - Wait a few seconds after each chunk

## It still doesn’t work :(

CAN devices can be extremely tricky, for example spedometers. Depending on your dump, you may have to try it multiple times with the same dump because of packet timings and/or bad luck. If you replay your whole dump and see the desired action, you will be able to find it using the searchter tab.

## I want to do it manually, how can this tool help me?

Create a new sender, add the dump to it and send them in a loop. Minimize the packet set from the bottom using your “CTRL+C” and “DEL” and try again. If it didn’t perform the desired action, paste the packets again and delete other packets.
