Researchers Find Same RSA Encryption Key Used 28,000 Times
itwbennett writes In the course of trying to find out how many servers and devices are still vulnerable to the Web security flaw known as FREAK, researchers at Royal Holloway of the University of London found something else of interest: Many hosts (either servers or other Internet-connected devices) share the same 512-bit public key. In one egregious example, 28,394 routers running a SSL VPN module all use the same 512-bit public RSA key.

Cars, too.
Funny anecdote: Quite some years ago, my wife and I were over at another couple's house for our semi-regular game of Pinocle. After we called it an evening, I went out the door and accidentally got into their Ford Escort (at the time, they owned one that was a very similar color to ours - plus it was night). They stood there and laughed at me... and then I started their car with my key.
