Re: Google doing a distributed wardrive?

samy's script and the other one gave me same results, but not accurate almost 10 km away.

I was using samy's script. I suspect that the result bears more
relation to where my cable modem equipment terminates than the
location of the wifi devices. Ask me if you want any more testing
done.

Jim, do you get the same results with both the script and Samy's page?
Thanks,

I got exactly the same behaviour with my non-android phone and home
router, a location bang in the centre of a nearby town. Perhaps google
have lowered the resolution of the service in the uk?

The topic of Android phones reporting the access points they see back to
Google interests me. I had been talking to Kevin Johnson about it just last
week. Today I heard about Samy's project from ISD:

But awhile back at Hack3con, DaKahuna showed me this script:


#!/bin/bash
if [ $# != 1 ]; then
        echo "# Google Gears WiFi Geolocation API query, by ShadowHatesYou"
        echo "# shadow () squatthis net"

        echo "#"
        echo "# Use: $0 MAC "
        echo "# $0 00-C0-26-A9-42-F7"
        echo "#"
        exit;
fi;

curl http://www.google.com/loc/json -H "Pragma: no-cache" -H "Cache-control:
no-cache" -d "{ \"version\": \"1.1.0\", \"host\": \"maps.google.com\",
\"request_address\": true, \"address_language\": \"en_GB\", \"wifi_towers\":
[ { \"mac_address\": \"$1\", \"signal_strength\": 8, \"age\": 0 } ] }"

It apparently ties a MAC address to a geo-location.  When he put in the MAC
address for my class router, he was able to find it's location when I had it
on down in Atlanta (I doubt a Google streets car just happened to be going
by at that time). Unfortunatly, I'd sometimes get bad results from the
script above (it would use my current IP instead of the MAC I gave it to do
the geo location), maybe Samy's stuff will work better.

Geo locating the router is not such a big deal I suppose, but DaKahuna also
said he was able to pic up the location of an Android phone if he knew it's
MAC address. Anyone care to test this for me? Might be interesting if you
could track someones location only be seeing their MAC address once. All
I've been able to replicate is the location of a router MAC.

I just tried this script with my MBP, my wifes phone and my own phone.
All three come down to the same lat/long which is the other side of
the city to where I am but at least gets the city right.
