The History Of The (Fake) 'Free Public WiFi' You Always See At Airports
from the an-accidental-XP-virus dept
If you travel a fair bit, as I do, you’ve noticed at almost every airport that there’s an “ad hoc” (i.e., computer-to-computer rather than computer-to-WiFi) option called “Free Public WiFi.” It seems to be everywhere. I’ve never connected to it, because I know enough not to connect to an ad hoc offering, but I was always amazed at the fact that I see it in pretty much every airport I’ve been to. I had wondered if it was a honeypot scam for a while, but I couldn’t believe that scammers would be able to set up such honeypots in so many airports worldwide and no one would catch them and take it down. So how could there be such “Free Public WiFi” (which obviously was not what it claimed to be) in so many places?
The answer? Well, it’s all Microsoft’s fault.
Apparently, there was a bit of a bug (one of many…) in Windows XP in terms of how it handles certain situations, and it effectively created a “virus” in that unwitting travelers around the globe are all broadcasting “Free Public WiFi” from their computers without realizing it, after they tried to connect to such a network:
When a computer running an older version of XP can’t find any of its “favorite” wireless networks, it will automatically create an ad hoc network with the same name as the last one it connected to — in this case, “Free Public WiFi.” Other computers within range of that new ad hoc network can see it, luring other users to connect. And who can resist the word “free?”
Not a lot of people, judging from the spread of Free Public WiFi. Computers with the XP bug that try to connect to the Internet will remember the name, create their own ad hoc networks and entice other users wherever they go.
And so it continues to spread. No one’s quite sure where it started, but somewhere way back when, someone set up such an ad hoc network in an airport (perhaps as a joke or a honeypot), and it got picked up by others… and then it just continued spreading. Eventually, it should die out as Windows XP machines finally go extinct, but for now, enjoy (but don’t bother connecting) the “Free Public WiFi” found in so many airports…
