question 126

Multiple Choice

A security engineer is assessing a new IoT product. The product interfaces with the ODBII port of a vehicle and uses a Bluetooth connection to relay data to an onboard data logger located in the vehicle. The data logger can only transfer data over a custom USB cable. The engineer suspects a relay attack is possible against the cryptographic implementation used to secure messages between segments of the system. Which of the following tools should the engineer use to confirm the analysis?

• A) Binary decompiler
• B) Wireless protocol analyzer
• C) Log analysis and reduction tools
• D) Network-based fuzzer
