      It's not geolocation in the traditional sense, because it's not mapping an IP address to a location. It's combining an XSS attack which gets your mac address from your router (from the inside of your network) with google's MAC to location lookup from their massive drive-by wifi sniffing done when the streetview car drives past your house. Typically a server can determine your IP address, and use that to map your approximate location. This can determine your MAC address and (in some cases) use that to determine your EXACT location.

      Of course, you need to have:

      a) not changed the default password on your router
      b) have a wireless network google has sniffed

      What I'm not sure about is if google's sniffing gathers the mac address of encrypted wireless, so possibly this only works on unencrypted wireless connections. I don't if a wireless router reveals its mac before or after encryption is established. Anyone?

  38. Who needs XSS? by darkain · · Score: 0

    I cannot count the number of ISPs that I've had to deal with where if you do a reverse-dns lookup of a user's IP address, their MAC address shows up in the DNS name given by the ISP's DNS server. Moreso from this, virtually every wireless router I've worked on to date has the WAN, LAN, and Wifi MAC address in sequential order.

    So, who needs XSS for this? Simply pull a reverse-dns of the IP address, and odds are that the MAC address will be +- 1 or 2 away from the WAN MAC that the ISP just handed over to you.

    On a side note, I looked up my MAC address using that tool, and they have me pegged down EXACTLY to my house. That almost makes me want to switch my MAC address on my wireless now (which thankfully is quite easy on Tomato firmware)

  39. Wierd by ichthus · · Score: 3, Interesting

    I have two Wireless APs -- one of which is only active occasionally for guests. Here's what I got when I entered my MACs:

    Everyday (always on) router: It found my city, but the address was about two miles away.

    Guest router: It pinpointed my father-in-law's address. This is strange, because my router has never been located at his house. But, HE HAS CONNECTED TO MY ROUTER. Interesting.

    I checked the first address again, and this would be a friend's house, who I once connected his laptop to my network when I was fixing it.

    I'm not completely familiar with 802.11, but it would appear that computers that had previously connected to my MAC are regularly pinging this MAC in such a way as to be received by the Google drive-by's and recorded as actual MACs of actual APs. Is there another explanation?

      It's reassuring to know that there is a 1:1 relationship between devices and mac addresses and that each device in the world that requires a mac address has its own very unique mac and that there is no duplication. Heaven forbid the calamity that should arise if there was any duplication at all.

      Possible scenario for your guest router:

      - your father has likely given Google the exact location of his laptop, while at his own home. Can be very useful for personalising search results.

      - also because he's done Google searches before so probably he's got a cookie uniquely identifying that laptop, if only for those personalised search results.

      - he connects to your guest router: Google finds that this laptop now has a new MAC address, and uses the previously known location information to link to the new MAC address information, not realising he's not at his "own" location but at someone else's location, and for lack of more information on that MAC address they use his home location as location for your guest router.

      Considering the amounts of data Google can grab from your searches and so, I don't think this is too improbable.

    I am amazed that this actually is tracked by the google van or whatever. It found my old address based on the mac address of my wireless adapter in that particular router. The wan and lan addresses were not found. So it appears that google has a list of many MAC addresses and their locations. Quite scary, and obviously impossible to opt out of.

    I really hope some north american government looks into this. What possible non abusive use could this possibly serve? At least the router i am using allows me to change the mac addresses, which is what i am doing now.
