The MAC could remain unchanged for established connections while changing for new connection offers. What does that accomplish? It accomplishes what changing it in the first place is intended to accomplish - anonymity.

Randomize your WiFi MAC address on Ubuntu

Changing for established connections offers no benefits. Good tip, thanks for linking to this. I wish their readme would show some examples of leaked information from reference dhcp clients, so we could tangibly see why that's an improvement. Identifiers in DHCP requests is a really good point, thanks for raising this. I'll do some captures and see what my client is revealing. MAC address randomization is in fact built in to NetworkManager edit: 1.

NetworkManager also includes more advanced modes which make the MAC address stable for a given hotspot, but random between them. Unless you're using Ubuntu From the post: "I learned that NetworkManager 1. If I just change my mac address every time I join a network even the same one , they can't track me with my randomized mac addresses. So why would I prefer to keep a stable but randomized mac address for each network I connect to for a day? Some bits of the MAC address are significant. You're generating all 48 bits randomly which could have some side effects.

Would love to know which side effects there are. I've never encountered any problems in all those years I use those randomly generated mac addresses. I also used to randomize my local hostname. I don't want to do the math now, but I expect that a collision is pretty unlikely. If you mean that some cards have problems with handling those mac addresses, I would love to hear about that. I'll integrate that in the future. Intel cards and Realtek cards are known to be problematic with random vendor prefixes.

Because maybe you had to pay to access the network and part of that involved binding your mac address. For example, calling the hotel desk to get your device to work. Would be interested where that happens because I've never encountered something like this binding the mac to the access in public networks e. McDonald's, hotels and other shops. I did only get access codes which could be used for a specific time where I just changed my mac address. I only know about mac whitelisting in protected networks managed by wary administrators.

There are hotspots all over the place, access control by MAC address. It's simply putting a "timer" on the MAC address. Then randomizing that address gives you a new hour every time. Try not to abuse this on a shared network obviously, but if you have a legitimate need it's very simple. All of the universities I attended used MAC address whitelisting. Wouldn't make any sense for properly securing a network.

As an attacker you could just create an evil twin same ESSID , let some students connect to it and just use their mac addresses and even drop their connections when they try to use the university wifi. Edit: You don't even necessarily need an evil twin to get their mac addresses. You only have to listen to the wifi traffic and get some - even encrypted data packets still contain the raw mac address as far as I know.

I didn't say it made any sense : This is how I was able to get my Playstation connected up in my dorm. I set my laptop's MAC to my Playstation's, then got my laptop authenticated using their tool, switched the MAC back, and the Playstation would connect up without issue. There's probably a one-liner in Linux too, but not one which satisfies the three caveats in the post. OpenBSD is more integrated, so advanced functionality like this tends to be easily accessed through ifconfig. If anyone here's involved developing NetworkManager, it would be brilliant to see a 'stable-for-n-days' type setting.

This would prevent a WiFi network tracking you over time, as well as between networks. JepZ on Dec 3, This seems like a good idea until you realize that you are the only one using a random mac address. There is a vendor prefix at the beginning of every mac Better would be to take a bit more care in choosing a more realistic address. I think it's not a good idea to change your mac address as your only precaution against tracking. The DNS requests you'll make will reveal which sites you frequent.

I would advise to use a VPN connection. In this case it doesn't matter that you've randomized your mac address in a way which can be clearly identified as random. And even then you can see the VPN server IP in the logs so you should also make precautions and buy your VPN connection anonymously and even then - you'll never know if you're really anonymous. Changing your mac address seems to be sufficient in addition to the VPN usage to prevent easy tracking through something unique like your real mac address.

But I agree that this is just lines of code for realistic mac address generation so it should be unproblematic to add. Edit: If you have fears of being uncovered by random-looking mac addresses without vendor prefixes, changing your mac address will probably not help you. Your threat model is different - maybe APT-level - and you have to do way more than changing your mac address. Unless avoiding this becomes common practice and then the whole story changes.

Yes, this is also my reasoning. No but it would make more sense to start tracking then based on their other behavior. Tharkun on Dec 3, If you're paranoid enough to be spoofing your MAC address, surely you're paranoid enough not to rely on shady DNS servers? You can spoof DNS requests of a victim when you are in the same network as them the router knows which sites you visit through those DNS requests anyway. It doesn't matter which DNS server the victim uses. As long as they don't use encrypted DNS they expose the websites they visit.

Or if you are an attacker without control over that router: search for dns spoofing. I did this several times to demonstrate companies that their public networks can be hijacked. Be aware that this technique could be illegal or appear suspicious in some jurisdictions. MAC address randomization was mentioned in Aaron Swartz's indictment for wire fraud. Can you show me where changing your MAC address is illegal?

CJefferson on Dec 3, The law cares about intent. Changing your Mac address, or wearing a fake beard, are both fine. Changing your Mac address to trick a Wi-Fi hotspot which gives out one hour free per device per day, or using a fake beard to trick a shop keeper into letting you get "one free bagel per person" twice, is a crime. This is what I was getting at. It's not illegal, it can be detected and then used against you in an indictment. It's like saying you dislike someone, they go missing, and the prosecutor mentions what you said.

Fnoord on Dec 4, And then what? You're under further suspicion? If you're innocent, that shouldn't be your concern. But all you gotta do is STFU. Don't talk to the police either way. What you said shouldn't be enough proof except in a banana republic. If you were always spoofing your MAC address however, then you can use that as your defense.

Your argument is akin to it being suspicious that you use Tor. As if that means your computer should be seized because you might have WMDs. Tor usage might make you suspicious only if other credible factors exist. What effect does being a banana republic have on this? Fnoord on Dec 5, A politically unstable country has ample amount of corruption and therefore likely has a weak, unfair legal system.

They do this with their wardriving vehicles and from Android phones.

So google can still see the three routers around you, look up the gps those routers have been seen concurrently with, and know where you are.
