    I see many posts that say, Change your Mac Address, and this will hide the Machines Identity? like at WIFI Spots ect...

    Well , My Router lists the Computer Name along with the Mac address assigned to any machine that connects to it, so you can change your mac all day long but it will be null if you have a Unique Computer name that is always the same.

    Just remember to change your Computer Name at the same time when you change (spoof) your network adapter's MAC address.

    use a live CD like TAILS or Ubuntu and fake the Mac addy from there :) You even get the added benefit that nothing is saved to disk

    When a mac address changer is used, the NIC's (Network Interface Card) permanent mac address is retained in firmware while the new mac address identity is sent in packets over the Internet for the remainder of the session.

    No you can use an external WiFi card in this case. This is why I said a live disk is better. You can use the internal one then and no evidence is left behind as it was all in RAM.

    If you change your mac address (before enabling your Internet connection or disable your network before browsing or before you turn on your router after booting your computer), then only your spoofed mac address will be transmitted in packets after you re-enable your network connection.

    So just to get this straight:
    Boot up a virtual machine to an Ubuntu live cd > make sure you are using a usb wireless dongle -NOT your internal card > use a free wifi spot, and your anonymous?

    Yes. Assuming you don't leak personal data like email address etc. while online. Depending on what you are doing you could add TOR. But as this stands even if they track it back to the open AP it won't match your laptop so they won't have any evidence.

    Great thread.


    What affect does using a different disc image, like one created in Acronis, have on your computer and leaving a trail of evidence?

    For example, say I use the technitium mac changer and change the mac address, change the computer user name and then I create a “disposable” disc image.

    So then I have a project or task to complete. Before doing it, I switch disc images to my new disposable image. I change the mac address again, run a straight connection, no router, and then use Tor. Upon completion of the task, load my regular operating image and delete or discard the “disposable” image.

    How safe would that be?
    Would a forensic examiner be able to find traces of the “disposable” image on my computer?
    Assuming the mac address was properly spoofed, wouldn’t that work? (and yes, I know that using a free wifi hotspot would be the safest approach).

    So a public wifi can see your computer name, but is your computer name visible on the internet while connected to your own router at home?
