Keyless entry has become a standard feature in almost all cars, and it was once a luxury option. However, this has also changed the way the thief breaks into the car. After recent research, [HackingIntoYourHeart] Claims to be able to access many modern Honda and Acura vehicles through a simple replay attack Use cheap hardware.
This is a bold claim, and we hope to see a third party confirm this claim. The crux of the allegation is that just recording signals from Honda or Acura keychains is enough to endanger the vehicle. According to reports, no rolling code system has been implemented and commands can be easily replayed.
Given these command control functions, such as unlocking the door, opening the trunk, and even remotely starting the vehicle, this is a worrying situation. However, there are also some surprises. Rolling code technology has existed for decades, which makes basic replay attacks more difficult. Nowadays, range extender attacks against key fobs located in homes or gas stations are more common.
It remains to be seen whether Honda has committed a safety foul, or whether more things are at work here. If you have more information, or have been able to recreate the same hack on your own Honda, please let us know.
