12ATTACKING WIRELESS SYSTEMS WITH SDR

In this chapter, we’ll delve into embedded wireless systems, beginning with embedded systems that transmit simple wireless signals to the ECU. Embedded wireless systems can be easy targets. They often rely on short-range signals as their only security, and because they’re small devices with specific functionalities, there are typically no checks from the ECU to validate the data outside of the signal and the CRC algorithm. Such systems are usually good stepping stones for learning before looking at more advanced systems, such as those with keyless entry, which we’ll look at hacking in the latter part of the ...
