    A website won't see your MAC at all.

    Ok, then while browsing, what parameters are actually made visible to them, besides the IP and the user agent/browser. Do they see a hostname of sorts? (Sorry, im still getting the hang of things)

    While generally true, it is possible for your MAC and even LAN configuration to be sent to a site if you let it run Java applets.

    That takes me to the following point:

    You would be surprised at the amount of data the average browser leaks. I will leave a few links here for you to read.

    Anonymity test (basic)
    IP check
    Panopticlick
    BrowserSpy.dk

    Enabling JavaScript, cookies, Flash and Java on a per-site basis will eliminate many of these concerns. The rest are rather hard to address if your browser isn't Firefox (I once built a really secure Fx setup, but had to change back to Opera due to slow speeds ).

    I won't lie to you: if you're an average user, your reaction to doing the above things will be negative, because many places require JS and cookies to work. But you can add exceptions for all your favorite sites, and then it gets better from there.

    I found something interesting yesterday. If you're using a wireless connection and MAC-changing tools don't seem to work on it, read on.

    Apparently, some manufacturers disallow this as a way to mitigate malicious usage. In this case, a workaround is only using MACs where the second bit is set to 1. This article explains it better than I could.

    The following batch file can be used to generate a fraction of all possible random MAC addresses which comply with that requirement, then use macshift to apply them.

    Code:
    @echo off
    SetLocal EnableDelayedExpansion
    set INTERFACE=Wireless Network Connection
    rem Change that if you've renamed it or have multiple NICs
    echo Press a key to continue.
    pause > nul
    echo Creating random MAC address...
    rem Copyright http://jakash3.wordpress.com/2009/10/18/random-string-generator-bat/#comment-321
    set len=1
    set alphanum=AE26
    :getChar1
    set /a index=%random%*4/32767
    set out=%out%!alphanum:~%index%,1!
    set /a len-=1
    if %len% GTR 0 GOTO getChar1
    set MAC=0%out%
    set len=9
    set alphanum=ABCDEF0123456789
    :getChar2
    set /a index=%random%*16/32767
    set out=%out%!alphanum:~%index%,1!
    set /a len-=1
    if %len% GTR 0 GOTO getChar2
    set MAC=%MAC%%out%
    macshift.exe -i "%INTERFACE%" %MAC% | find /i "Setting MAC"
    echo Press any key to exit...
    pause > nul

    Digging it up.

    I get why one would change his modem MAC. But is there any point to change your local machine MAC ?

    • Evade limitations enforced by checking your MAC address (like the free data traffic on Hotspot Shield)
    • Concealing your network controller's manufacturers from software and other people on your network
    • Because you can

    Windows 10 prevents MAC address spoofing via registry. Unless your NIC _specifically_ has this feature you are boned.

    technitium mac address changer seems to just get the job done, at least for me. Pure spoofing.

    Did you tested on Windows 10?

    I know. technitium was the best of its time. And it worked fine on 98, 2000, XP, Vista, 7, 8 but I don't know if it works on 10.

    A MAC changer sets a registry value and resets the network adapter (everything else is extra functionality). This tells Windows the new address is to be used, but I don't know how the workflow goes from there. I know drivers can reject MACs that don't have the locally-administered bit set, and they may also be able to ignore the NetworkAddress value altogether and disallow MAC spoofing.

    I don't have a Windows 10 system to test this on, so I'd also appreciate feedback on that regard.

    Needless to mention you everyone should also enable the option in Ublock Origin settings ''Prevent WebRTC from leaking local IP addresses''...
