Washing Post has an article today about the increase in signal amplification attacks resulting in burglaries with no sign of forced entry:
“Thieves have been hacking into so-called keyless entry systems that permit many cars to be opened and closed remotely with the press of a button, police said this month on an email bulletin board.
They say an electronic device held close to a car prompts a recognition signal. Additional equipment amplifies that signal and sends it to the wireless key in the owner’s home, perhaps dozens of yards from the car.”
