Show of hands: how many of you have parked your car in the driveway, walked up to your house, and pressed your car’s key fob button thinking it would open the front door? We’ve probably all done it and felt a little dopey as a result, but when you think about it, it would be tremendously convenient, especially with grocery bags dangling off each arm and the mail clenched between your teeth. After all, we’re living in the future —  shouldn’t your house be smart enough to know when you’re home?

Reverse engineer par excellence Samy Kamkar might think so, …read more

[tomwimmenhove] has found a vulnerability in the cryptographic algorithm that is used by certain Subaru key fobs and he has open-sourced the software that drives this exploit. All you need to open your Subaru is a RasPi and a DVB-T dongle, so you could complain that sharing this software equates to giving out master keys to potential car thieves. On the other hand, this only works for a limited number of older models from a single manufacturer — it’s lacking in compatibility and affordability when compared to the proverbial brick.

This hack is much more useful as a case study …read more

We all do it — park our cars, thumb the lock button on the key fob, and trust that our ride will be there when we get back. But there could be evildoers lurking in that parking lot, preventing you from locking up by using a powerful RF jammer. If you want to be sure your car is safe, you might want to scan the lot with a Raspberry Pi and SDR jammer range finder.

Inspired by a recent post featuring a simple jammer detector, [mikeh69] decide to build something that would provide more directional information. His jammer locator consists …read more
