Fuzzer Tab

What does this thing to?

Using this tab you can send random packets into the CAN bus to discover things. You can tune settings that control random packet generation using the GUI elements.

What are masks?

You can write static values into the masks or put an X if that character should be randomized. Using this, you can freely control the payload of generated packets. Hint: You can change masks and lengths while fuzzing.

Other fuzzers are much faster!!1!

This is a python based fuzzer which also displays the packets on the GUI. This convenience costs performance. If you want the best performance you can use cangen of the can-utils package and import the created packets later.

What are the modes?

• User specified: You can freely specify ID and data masks

• 11 bit IDs / 29 bit IDs: Only short/extended IDs will be used
