Does Not Really Work #7

Closed bulk001 closed 10 years ago

bulk001 commented 11 years ago

If you download a MAC address utility that detects Mac addresses like The Foundry License Utility (http://www.thefoundry.co.uk/support/licensing/tools/), you will see that it does not really change the MAC address.

I'm not familiar with FLU, what do you mean by "does not really change"? Did you wireshark your outgoing traffic?

FLU is a simple utility that checks for your MAC address (a lot easier to run it than terminal). If you run the utility you will see that even though LinkLiar seems like it changes your MAC address your real MAC can still be seen by apps like FLU and so I am sure, by any admin on a network who wanted to see / ban your mac address could still do so. If you can fool FLU then you have really accomplished something as it will provide users real anonymity.

You could also just go to your network preferences, it will tell you your hardware MAC address.

Of course, the hardware address cannot be changed and any application running on your computer can query the hardware it's running on.

and so I am sure, by any admin on a network who wanted to see / ban your mac address could still do so

That's a bold assumption :) Being an application on your computer, or being a network administrator without access to your computer, are two very, very different things.

If you can fool FLU then you have really accomplished something as it will provide users real anonymity.

I guess that level of anonymity can only be reached by anonymously buying a brand new network card and use that to connect to the rest of the world. Only then will applications on your computer not know anything serious about the network card inside of the computer.
