    Dear bros,

    When accessing a network, I know that the network admin can collect some info such as Computer name, Mac Address, OS Name, OS Version, ... I'd like to know how to hide or fake these info?


    For example, I'm running Windows 7 Ultimate x64 on a Dell notebook with given X as MAC Address. How can I change these info so that when I access a network, the network admin will see that I'm running Windows XP SP3 on an HP notebook with Y as MAC address.


    Thank you for reading this post. That'd be great if you can help or share some useful info :D

    The NSA should know how to do this. Don't know if they would be willing to share, however.

    Try tweeting Edward Snowden. I'm sure Putin won't mind.

    Try Tails.os. I have not used it but their homepage is very detailed and impressive. And it is free.

    The change of that Mac address isn't permanent, just temporary till the next boot! You could do it kind semi permanent while using an Macro Apps or Script which changes the Mac address at every boot!

    Yes, you are right. On Windows, I use Change MAC Address program. However, I don't know how to automatically change the Mac Address every boot :(

    We network admins just love folks like you... it's already hard enough to keep track of stuff, without having to figure out what's fake.

    Done like I wrote above, just opposite!

    As Network Administrator and if that Network is in good order, you'll also use an Hardware Firewall like Netscreen25, Cisco PIX-500 or similar, or as I use Smoothwall! That would gives you the ability for to allow only 'fixed' Mac addresses for to use the LAN and if they're not in the list, they would be blocked totally! If someone within that LAN would change the Mac address, it would automatically blocked for in- and outgoing traffic, means also no internal connection to any other device, computer, printer or whatsoever that is! So, what's the deal?! The overall question is: How the Network you work with is designed and what level of security is used?!

    MAC whitelist helps so they can't hide it, but then you need a way to make sure they aren't spoofing for that to get on, so it depends on purpose. Are you trying to block clients or just track them?

    I have MAC whitelist at home so nothing except stuff at the house can get on the Wi-Fi. It would keep the average person who somehow got the password from doing anything since you'd need to know one of those addresses to spoof and the average person doesn't know how to do that.

    For private use that's much enough! But company networks! Special if the company is developing new products or complete product lines of well known and good name brand products! And for sure the most important department of an SME or bigger Company, the Financial Department, need to be as secure as possible!

    It's all about what level of security you'll need?! And cost is an factor as well!!
