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…

Apparently, there was a bit of a bug
In a Microsoft product? I don’t believe it.
“Eventually, it should die out as Windows XP machines finally go extinct…”
It might take a while. According to some numbers (sorry, no citations, I don’t remember where I saw it 🙁 ), about 60% of current windows machines are still running XP (some people are just “happy” with what XP offers, for various different reasons). I personally don’t see myself switching away from XP for a while. I only use it for gaming and the “Vista Series” just don’t offer enough RtB.
Re: Re:
I saw those same numbers, 60%, but that was a few months ago. The number has dropped, slowly.
As for upgrading, if your PC runs, don’t. Just make sure you’re on SP3. When it dies, I recommend Windows 7. It does provide better support for gaming.
Re: Re:
Wow. “Vista Series” and you wrote this on Oct 11th, 2010. We all know Vista was a complete failure and was just another pushed release of crap like WinME was. Try windows 7, you’ll leave your XP behind.
Re: Re:
I still see offices running windows 95 in 2011, I don’t think we’re out of the woods quite yet.
Glad to see this.
I’d been wondering why you see these ad hoc networks at every airport for the last 5 years or so.
One of life’s mysteries solved!

XP service pack 3 fixed the problem. So if you see a Free Public Wifi or hp printserver in an airport it probably means the system is missing a bunch of security updates. This situation effectively advertises that the computer is at risk. You might as well hang out a sign that says, “Please hack into this computer. It is sitting wide open.”
Re: sp3
Uh, sorry, I have SP3 on a fresh install and I still get this.

I've seen this more in Hotels than Airports
I see this more commonly in hotels than airports. 😉
Re: I've seen this more in Hotels than Airports
Mike, your post doesn’t cover everything that is going with regard to open ad hoc networks while traveling.
As noted in the above comment, you do indeed see this open ad hoc connections more in hotels than airports, and it isn’t necessarily because unwitting travelers are ignorant of the need for patches. Some people who, for various reasons must pay for an internet connection in a hotel, then proceed to open up ad hoc network sharing of their internet connection as a (passive agressive) protest against the the internet charges their hotel is levying which they deem to be too high. Do a little reading on the web and you can find discussions of exactly this issue.
worth noting
Hard to believe I’m defending (sort of) Microsoft, but as mentioned in the article, this is an old bug.
It was fixed with XP Service Pack 3. If I had an XP computer that was last updated two years ago, it would be safe from this one.
Not that it’s any palliative, but people running around with Windows computers that out of date likely have way bigger problems than the ad-hoc exploit.
Some of those computers will be so compromised and laden with adware, download accelerators and toolbars that they can barely get online at all. Others will be the same machines flinging shit at those aware enough to keep their computers reasonably protected, if not avoid Windows altogether.
Has this “Microsoft” error been verified? as I have several XP pc’s that are not up to date. So I tried to recreate this error with my computers. I didnt find any new adhock networks ( after disconnecting my wireless connection, I changed the name of it, and left the XP computers to try to connect to the old network. I then tried searching for my old network name. Nothing… It would appear that at the airport you were hacked my friend. Perhaps you should put the blaim to where it truely belongs, on your own lack of security. What we have here is an ID Ten T error..
Re: Re:
Yes, it has been verified. This is actually a pretty well known issue and as stated, was fixed years ago. I’m kinda surprised this has gotten some press. People running around with years-out-of-date patching on a 10-year-old operating system is the norm.
Maybe you should get your system up-to-date, preferably with something other than a decade old OS, before you start calling others idiots for not knowing hwo to secure their systems. Also, your “testing” missed the key element of actually connecting to an ad hoc network first.
Re: Re:
you should probably make sure you understand the issue before you go calling people idiots.
And how do you figure he was hacked because he’s seeing other people with a Free Public WiFi ssid?
Re: Re:
You blaim [sic] him, and say he was hacked because he viewed the SSID “Free Public WiFi”?
I’m quite sure viewing SSID broadcasts is not a threat vector. If so, Google streetview systems would be the most virus-laden computers in the land.
Re: Re:
“Perhaps you should put the blaim to where it truely belongs, on your own lack of security. What we have here in an ID Ten T error..”
Are you kidding? First off, blame*, truly*, and “where” – not “to where”. You obviously don’t know what you’re talking about, and the fact that you couldn’t get it to work is the real ID10T error.
Re: Re: Re:

Re: Ugh
Do just shut up. The “Free Public WiFi” is an acknowledged phenomena for over 5 years, and it is a Windows bug.
Back when I was younger and meaner, I set up a guest network called FreePublicWiFi or FreeInternet at my apartment. They were only able to download at 100 Kbps and all of the good stuff was blocked. Rummaged through their computers for music and programs though. Found some interesting pics and some good indie music.
Ah, those were the days.

If you think this is just a small thing. Try putting up a wireless network for a trade show or large press event. Devices try to attach to ALL the remembered SSID’s and the latency goes through the roof of the building.
Welcome to 2010. You have been sleeping for the last 10 years.
This has been known since about 2001.
Re: Welcome to 2010. You have been sleeping for the last 10 years.
The word “History” in the title eluded you?
I made Free Public WiFi at my school in like… 2004. Not sure who was ever the first to do this but when I suddenly started seeing these in major cities close to me I wondered if students from my city were going back home with it in their XP laptops.
I even wrote an article about it.

Not A Virus, A Prion
I think ?prion? is a better biological analogy than ?virus?. If genetic material is analogous to code, then this ?Free Public WiFi? has none. It is, in effect, a rogue, self-propagating configuration state of the system?which is exactly what a prion is.
Re: Not A Virus, A Prion
As a molecular biologist I totally agree with your statement, but prion is hardly in the common vernacular.
More recently . . .
There’s an actual non-virus that took advantage of a security fault in OS X more recently, about a year ago, which infected other macs that tried to connect to “Free Public Wifi”.
The only effect was to make it broadcast that network name and pass it on further. Thus why I call it a non-virus.
To my understanding, it was purposely made to catch attention and make someone patch the bug. So it only spread for about 10 days until a patch was made and distributed. In those ten days, it spread ridiculously far; China, Northern Canada (NORTHERN Canada), Sweden and Argentina all had confirmed cases of this on OS X machines.
No patch was ever made to remove the harmless non-virus. So some macs still advise it, but it can’t spread anymore.
So yeah, just in case some of you had tracked down the signals and were scratching your heads at why some macs were broadcasting a known windows thing . . . now you know.
There’s a great episode of a show called Hak5 that deals specifically with this, using a device called the pineapple where you can fool people to connect to the pineapple to become a man in the middle.

You don’t understand what the words “ad hoc” mean. It means something inserted into an argument so as to make it work in an last effort attempt.

Heh. I understand what it means in the linguistic context quite well. But I also understand that it has a meaning in wireless networking:

Re: "ad hoc"
You’re thinking of “ad hominem”.
Now I want to make a joke RFC about “ad hominem access points”.
HI I CAN MAKE ANYONE A I.D. THAT WILL SCAN AND HAVE HOLOGRAM, AND IT WILL PASS ALL UV LIGHT TEST. YOU WILL BE ABLE TO USE THIS I.D. ANYWHERE AT THE BARS,CLUBS,STORES,AND BANKS. THIS WILL BE A FLAWLESS I.D. COMING FROM ME IF YOU WANT MORE INFORMATION EMAIL WORKSTUDIO360@GMAIL.COM
Yeah, I remember a bunch of those near my hotel in Baltimore, about a block away from the BCC. I would be in between without reception, but in one place or the other I could connect to it. Funny thing was, one or two of the other random unsecured networks in the BCC would actually work.
It’s not a bug, it’s a feature!
This is a very old bug and was already fixed by WindowsXP. People should update their computers=)
You have made valid points in your post and I agree with you!
This is a really excellent read for me. Must agree that you are one of the coolest bloggers I ever saw. Thanks for posting this useful article.

"Free Public WiFi"
I come across most of this Free Public WiFi networks and none of them worked for browsing Internet! But I heard that we can browse the files on the ad-hoc network’s host computer.
Most “free” public wifi networks are private services that entice you to pay hourly at airports and such. They broadcast under the guise of free, but to actually get internet you need to pay.
I think this was patched
I’m pretty sure they fixed up this little bug in SP3. I’m not positive though.
Either way, a substantial number of people are still running older releases.

I will surely share this awesome content to my friends, great job!
Airports should sue the writer of this article. They actually do provide free internet access, and this is discouraging people from using a valid, legal service.
Still going!
Denver International, “Free Public WiFi” spotted.
Considering that there are still people rolling with IE6, we’ll probably see SP1 XP well into the 2020s…
Are you kidding?
> one would catch them and take it down.
Who’s job would it be to go around and (first) try to even FIND which person at a huge airport is running the hotspot. Then (second) “order” them to turn it off. And (third) spend time “forcing” them to turn it off. (Not sure how you do that one.) And (fourth) make sure they never turn it back on again. (Like the minute you leave the room.)
Re: Are you kidding?
Um, I believe they go by the name of “Federal Police” in Australia and I assume they would have the authority to take the person into custody. Airport security may also have some authority to confiscate the equipment being used. And I’d be surprised if in this day and age, there isn’t software/equipment to help pin the culprits down, especially with SmartPhones and other things being used.
I reckon that the national police in a country would run a joint operation with local police to try and shut down such activities.
The real issue is whether the existing laws state that it’s illegal. Technology has exploded so fast that laws are still lagging behind.
And to the person saying airports should sue, for what? If you are literate enough, it’s quite clear this article is referring to a specifically-named network of ad hoc type and not the structured network offered by airlines. I was in an airport a few days ago and there were signs all over the place naming the airline-provided network which included the airline’s name; there was no chance I’d pick “Free Public WiFi” over [airlinename]FreeWifiHotspot or whatever long, clear name they provided.
Re: Re: Are you kidding?
By the way, “if you are literate enough” meant universal “you” not you the person I was replying to. Lawyers are literate enough and would promptly tell the airports and airlines that they didn’t have a leg to stand on, if they attempted to sue.
Wow, this thread is hot!
