MAC & IP address

[wod]

hi guys.

there are those applications by hide my ip : hide my ip & hide my mac
i know that the ip app works but can the mac app really hide ur mac address ?
how can i check ?

p.s
there are some free alternatives like:

You can easily spoof your MAC address with a number of tools.

can u please be more specific ?
do mean physical devices like some special adapter or comp apps ,,, ?

While it may be easy to spoof your computer's mac address, what about your hardware router's mac address? Afterall, it is your hardware router that defines your IP address to the world.

I assume the technique would be that after you have booted up your router for each computer session, you would need to login to the router under the router's admin account and run the command(s) that change the mac address, and then follow up after logging out of the router by changing your computer's mac address? And, you would probably need to do this every time you power up your system.

I am assuming that the firmware of the router/computer would retain its original mac address by virtue that it is hardwired into the NIC hardware circuit chip on each.

Note: the tool reference in post#1 is for Windows only systems.

thx a lot . now thats a helpful replay.

so what ur saying is that those apps like : Hide My Mac Address are hiding only the mac address of my network card ?

and what if i dont have a router ? i only have a modem .... (please dot get steamy if i wrote something dumb). i mean ... is the router included in the modem ? and should i hide the modems mac ?

besides i mostly use a wireless network of my university so does that mean i need to hide only my ip and network adapter's mac ?

sorry if i ask too much , i just really need to know

Are you worried about your MAC address being on router logs or what? I ask because nobody is going to get any of your MAC data via simple http over the web. MAC address vulnerabilities come into play after the fact; meaning that if you are suspected of using an internet connection that LEA has access to (router/AP logs) they can compare the access (say at a coffee shop hot spot) to the MAC address on a physical computer they have impounded. The sites you see supposedly showing your "MAC" address are simply shown on your computer, very reminiscent of the old tricks showing the contents of your "My Documents" folder that Evidence Eliminator used to play. They couldn't "see" squat - you could only see it on your own computer. The MAC address changing software is designed to provide cover - not prevent a site from getting the data. Using MAC-masking software you get 'cover' on the logging of whatever connection you're using, which would record the fake MAC info.

So using something like Technitium MAC Address Changer at a public wireless will prevent LE from comparing MAC addresses to a computer that they have in their possession. So what if a laptop is encrypted? Would that prevent someone from verifying the MAC address of that computer?

Your hardware MAC address hasn't changed, but your computer is no longer sending that address but the spoofed one.

If you do this on an encrypted operating system, all evidence of this spoofing is gone if they can't access your operating system. All LE will see is the hardware MAC address that was never sent to the router.

So, in short, full disk encryption + MAC address spoofing = untraceable

Thanks so much for that explanation. Much appreciated. So I am thinking that if I ever wanted to be more anonymous than I usually am, I could have a separate laptop used for strict anonymity only, encrypt the hard drive, only use it on a public wifi (never at home), and use a MAC address changer, and of course Tor or a VPN. I don't see how a person could be more anonymous than that. Except maybe geolocation will get so good that they can see you from the sky, license plate and all....LOL

There's a lot to be said for what you just wrote. Depending on the threat model, etc., it's hard to beat the anonymity of public wifi or even wardriving.

Hi caspian,

We've had the technology to discriminate license plates from optical satellites since the 60s! The question is whether the satellites are in position to directly view an object without interference from cloud cover, etc. and, of course, directly control the satellite to lock onto an object that may be moving.

hi thats a great and a simple idea - i can simply operate on public networks

thx , seems ur very knowledgeable in the field.
present a different MAC address to the router you connect to - yes thats exactly what i want to accomplish. any free-ware or pay-ware suggestons ?
- iv tired Technitium MAC Address Changer but it seems to do nothing .

If you do this on an encrypted operating system - what do u mean ? whats an encrypted OS ? and how can i achieve it?



thx for sharing knowledge guys . seems i found the right forum

Sorry, I'm using really old software (several years old) obtained by methods that I can't recommend here. Maybe someone else would have some current suggestions.




By what method did you check your MAC address? Maybe someone here who's familiar with the program can comment on any mistake you might have made. Also, what operating system are you using?



Sorry, that's beyond the scope of this thread. Look around on this forum for a program called v. Only every other thread here is about it. It can encrypt files, partitions, and the entire operating system (e.g. your Windows partition). By encrypting your operating system, you require a password to log onto your computer. And, without the password, everything is basically gone. No one can access it, not even you (if you forget your password).

Also try here. They have their own forum.
www.truecrypt.org

"I'm using really old software (several years old) obtained by methods that I can't recommend here " - im pretty sure i know what u r talking about .


By what method did you check your MAC address? - well , the app itself tells me its not spoofed ... besides it has a really ugly interference( irrelevant, i know .) and i think i got a replacement only that its cracked and norton online scanner gives a virus alarm (false positive i think ... kaspersky file scanner OKs it ).

TrueCrypt - that a great idea . right now im on win7 + commodo firewall ,so i think that should cover me up when it comes to inwards traffic (form the Internet ) but encrypting is generally a good idea. though if ill immigrate to Linux where im asked for my manager password for basically every thing, ill avoid those privacy issues to begin with right?
-only thing is i have no idea how to connect the web in ubuntu nor opensuse
onr any other linux OS

thx alot for ur knowledge u r awesome .

Again, spoofing the MAC of your hardware (say a USB wireless stick or a Wifi card) is easy. I've done it when connecting to neighbor's Wifi. Not sure how to do it on Windows, but on Linux it's easy. You can do it with stuff already built into the OS.

yeha i know but i cant connect wifi on linux -i just dont know how to do it . can u please link me to some guide?

Changing the MAC address is one of those things that's basically like 2 steps, and one program could be easily substituted for another. It's hard to recommend one over another when they all basically do the same thing in the same way.

I don't have Windows 7, but on XP, you can check your MAC address by pulling up the command prompt and typing "ipconfig /all". Find the relevant network adapter and look at it's MAC address. Also, I don't know if there are any additional safeguards in Windows 7 that prevent MAC address changing. Maybe someone could comment on that.

Another thing. When you pick a MAC address, make sure to start the address with either "00" or "0000". If you don't start it with zeros, there's a good chance it won't work.

Good luck.

thank u again , should be more ppl like u.

Are you sure about that?

[hierophant]

The MAC addresses that Samy Kamkar is using for geolocation are those of wifi routers, not MAC addresses of client machines. If you're not using a wifi router, this isn't an issue. If Google or some other wardriver has not GPSed the wifi router that you're using, this isn't an issue (but, to be sure of that, you'd want to have used that router only inside a tight Faraday cage).

This IS an issue, BTW, if you're leeching on someone's unsecured wifi router. Even using an anonymous VPN, connecting via a wifi router that's listed in a geolocation database could reveal your true location (if you permitted it, or if an exploit such as Samy's worked).

[wod]

so what i should get from all this is that there is no way i can hide my machines mac adress ? and what if i use a cellular modem - u know that usb thingy ... ? can they trace me then ? think its a great idea no ?

Faraday cage - yeha right...

Samy Kamkar is using for geolocation are those of wifi router- why do ppl do it to start with ? its like :"hi i m board , think ill design some worm and toy with ppl "

"If Google or some other wardriver has not GPSed ... " so many threats in the web. its like ...they control everything. its like they r the Microsoft of privacy.

if you're leeching on someone's unsecured wifi router - yep its a problem but its the same thing with coffee shops and private networks no ?

[wod]

is there some way to use jap /jondo and tor to cahnge mac too or just the ip ?
