Locate Any WiFi Router By Its MAC Address
coderrr writes "SkyHook Wireless has been wardriving the US for years creating a huge database mapping wireless routers' MAC addresses to their physical locations. They provide an minimally documented API (docs here) which allows anyone to query the database directly for any MAC address. This could potentially allow some malicious individual to find out exactly where you live. Of course for them to get the MAC of your router in most cases will require either being infected with malware or some sort of social engineering attack... Imagine if you got a phishing email that included your home address."
My niece asked me this, should she jump on someone elses WiFi, but this happened right after the big kerfuffle about the DNS hack.
You realize that you're giving all your data and control over to a machine that you don't control. You hope that it's open because the person is either an idiot or a good guy, but you have no evidence of either at that point. Even something as simple as checking your mail might give people access to your inbox, and all the 'password reset' notices you get.
