AT&T Identifies Widespread Security Hole - In Locks
__roo writes "The New York Times has an article [free registration required] about a researcher at AT&T Labs Research who has discovered a little-known vulnerability in many locks that lets a person create a copy of the master key for an entire building by starting with any key from that building, and it requires little more than a file and a few key blanks."
It's called a skeleton key. They've been around for a hundred year.
The trick is not giving keys to people who will miss use them.
Think of it as 'root' access for a physical lock?
