Another scary finding from the DefCon hackers' conference: prisoners could escape from their jails, if hackers decided to lend a hand and hack into the prison's security systems.
A couple of years ago a prison's cell doors accidentally opened after a power blackout, which led security engineer John Strauchs to make the startling discovery that it would be possible to maliciously release the cell doors in a similar way.
While he hasn't obviously tested it out on a living, breathing prison, it's worried Strauchs that prison guards use the internet on the very same computers that control their security systems. One click of a stray link, and the wall of security could fall away. [Huffington Post]
