Yep, it's a well known fact that all Macs are wide-open to hacker and virus' That's why we're reading so much lately about all the agencies being hacked and secret data being stolen. Let me guess, the firm that developed this "proof-of-concept also sells security services, especially for Windows machines?
BTW,
MAC stands for
Media
Access
Control address, a device's unique identifier. It has nothing specifically to do with a Macintosh computer, often called a Mac. Even Dell computers have a MAC address, as well as any printer, modem, hard drive...
Maybe it's just me, but I don't look to the Register form critical security information concerning a Mac.
