Decided to NOP out brute-force and JMP straight into the patching! 🚀 In this simulated ECU, I traced the SecurityAccess (0x27) check, flipped a conditional jump, and made the program JMP without correct key. Check out how I reversed my way in!

I wrote a Python code to simulate TesterPresents.
Considering the main purpose of TesterPresents, SessionControl and SecurityAccess are also implemented.

Check the results of the SecurityAccess simulation.
SecurityAccess behavior depends on session state, security state, and S3 timeout.
