    • No.. it won't.
      It's not about using up bandwidth.. it's simply the data packets that announce other APs as present.
      A very small amount of traffic, actually.
    • "Security through obscurity doesn't work" is an aphorism, not a law of thermodynamics. It's foolish to rely on obscurity, but there's no reason why it can't add an extra layer of protection.

      Same for Brooks' law, for all the people who love to invoke that one. It's not a formal proof that adding a developer will necessarily delay a project.

      • It's foolish to rely on obscurity, but there's no reason why it can't add an extra layer of protection.

        If you can't rely on it, why are you wasting your time doing it in the first place?

        Security through obscurity is never "protection" because you're not really doing anything - because people who believe it's useful do rely on it.

        That being said, I disagree that this is obscurity - like a honeypot, nothing is being hidden; I see it more as a way to waste a potential hacker's time.. if they try a few that are bogus, they'll give up and go elsewhere.
        • If you can't rely on it, why are you wasting your time doing it in the first place?
          Because security isn't binary, good security is about lowering the odds of a break-in. Obscurity achieves this, and it can often be a very quick way of lowering the odds of intrusion.
        • I would never rely on just a single system for security anyway. And something like this that is relatively inexspensive, and can get rid of a good amount of the undesireables is worth doing. Good example is leaving a radio on and lights on when you aren't at home - anyone that watches the house for more than a few hours will realize you aren't home anyway, but for a good percentage of (would-be) thieves, that is something that is just too close to work so they move on and hit your neighbor.
    • Would you consider passwords to be security through obscurity? Security through obscurity isn't a bad thing- it just shouldn't be what your security relies on.
    • I don't think this has anything to do with Security through Obscurity. StO means you keep the flaws secret, while a fake AP flooding is an entirely different matter.

      Not saying it's bulletproof, but if it makes it harder to get in and the cost is small then there's no reason not to do it.

      This is security by obscurity in the same way that chaff released to confuse a radar system is. You obscure a target so that attacking it with your primary mode of attack is no longer profitable.

      In other words, as many others have said, it's another layer of protection. I certainly wouldn't leave my network unsecured behind such a fuzz curtain.

      Just think of this as a form of radar jammer. It doesn't stop you from looking for the target. It just makes one of the easier ways of doing so hard.

    • You configure it to talk to your WAP.

      This product works a lot like a flare that is used to distract missiles or other military ECM. It's meant more as a distraction. I am surprised someone didn't come up with this idea before now.

      I think the point is that it will waste the potential intruder's time - not that it will totally secure your network. If the potential intruder WANTS to get in, he/she will get in eventually. This is to confuse someone trying to just do a drive by hit.

      Then again, there is no stopping luck - what if the person hits on the right access point the first time?

      I haven't seen any studies on wireless where people are finding Wireless AP's with the "Broadcast SSID" turned off (NetStumber can't find WAP's if you have the "Broadcast SSID" turned off)and MAC security enabled (you can clone a MAC address but you have to have a card that can do this function). If you are going to run a Wireless AP, why would you let any MAC hook into your system and why would you broadcast your wireless AP? Ok, you might have some clueless users who don't know how to configure their laptops and yes, it is a pain in the ass to have to distribute the SSID and the encryption Network key to everyone but why would you make it that much easier for an intruder?

      If you have a WAP that doesn't let you turn off the broadcasting of the SSID, why don't you research into either flashing the firmware to enable this feature or buying one that does let you do that? They aren't that expensive anymore.

    • Because you *should* know what your SSID is. Your correctly configured device will have no problem making a connection, but some 3viL Hax0r will have a hell of a time connecting.

      As for bandwidth usage - 802.11 is collision-based shared media just like unswitched wired ethernet.

        It's not security through obscurity, it's creating a forest around your tree. While I may be able to secure the machines on my network, use a VPN for all transactions over the wireless network, there's no real way to secure my access point. WEP is a joke, plain and simple. If someone gets on my wireless network unauthorized by me, I'm liable for whatever shit they might pull through my internet connection, so I don't see the supposed stupidity in making it alot harder for someone to find the real access point. I have my doubts that this software is as effective at what it's trying to do as it's author(s) claim, but even so, it narrows the potential abusers of my network down to the determined, patient, and lucky.

What, do you actually think I've got a Cisco with an IPSec module lying around that I can use merely for authenticating outbound web browsing? Are you clinically thick? Do you mean the wireless access point? How many consumer 802.11b access points do you think have an integrated VPN server built into them? None that I've found. Sure if you're an enterprise and have the cash to spend, and the need for wireless networking on a a large and secure scale, you can get a Colubris Access Controller, but I, and most of the other people fielding wireless access points for their homes, can't afford it. And even if they could, setting up a VPN securely is not a trivial task that just anyone can do. Neither is using a spare Intel box to run a xBSD or Linux-based VPN server, not to mention the issues involved in securing the VPN server itself, that many well paid system administrators and security professionals can't seem to do correctly.

    So I get a list of hundreds of access points. My trusty computer can be programmed to check them all one by one. Only the legit one will respond. I realize this is a bit slower, but I think the number of fake APs needs to be huge to hurt the war drivers.

    In fact, I think that the problem with this solution is the amount of effort expended in defense is equal to the amount of effort for the war driver. You've got to have a PC pumping out fake APs constantly. Both radio modems are putting out the same bandwidth. This isn't a good equation for most of us.

    Good encryption, on the other hand, takes only a few cycles to do but a gazillion cycles to undo. That's a great ratio of defense to offense.

    Plus, don't the fake APs still end up jamming the channel. If you're faking an AP, someone else can't use the channel on that micro second. Given that wardrivers come only occasionally, but the jamming goes on constantly, I think that the legitmate users will pay a big price in network access for something that would only slow war drivers down a bit.

    But I may be wrong.

    • The packets that announce an AP consume a tiny fraction of your available bandwidth. There should not be a noticable drop in bandwidth.
    • This sounds more interesting to me. I have no closely looked at the exploitation of WEP to see if introduces a low level (~1%) of improperly encrypted packets would cause problems or not. My guess is that it would, although you would have to be careful that the false encryptions were subtly wrong. What I do not know if how much harder it would make it. Perhaps more important, I do not know how possible it is to do with commercial cards.

      Of course, the much better solution would be if encryption was used properly by wireless networks. If you add a good key management system, it might even be usable (a globally shared key is just not a good idea). Many people are working on these, of course. Of course, it does not matter how good your encryption is if people do not use it.

  • The messaging of WEP security associations within the 802.11 mac spec is performed in the clear by passing challenge texts and responses around.

    So just compile a list of all the APs you see and listen out for a good security association. From this you can devine the real AP.

    With the proposed enhanced security mechanisms (TKIP & AES) the encryption similarly is not turned on until a security association (based on 802.1x) is completed. You can see this happen on the air and you can see which AP is being communicated with.

    For this to work well you might need to also fake lots of good security associations to all the fake APs that are beaconing.

    I see this is a poor mechanism. It is security through obscurity. It can be circumvented and the beacons suck away bandwith.

    TKIP is the way to go.

      Which is exactly why this is a bad idea. The software doesn't just send beacons. It requires to you install a driver which contains full AP functionality, and then starts configuring it with random MAC address and common, well known SSID's, every quarter second. Which means that anybody within range who happens to have "linksys", or "tsunami", or any of a handful of common SSID's is going to be out of luck when their laptop connects to whomever is running this Alchemy "tool".

Then you intercept the channel and ssid of their wlan, and you start to flood it with a lot of random packets using their channel and ssid.

    Come on! They idea is for them not to notice, and set up a barrier if they do. Not for you to set up a red light district.

  • Fine, We will sniff for probe packets then.

  • If you're smart enough and technically inclined enough to have a RedHat linux box to run this program on why not just run FreeRadius [freeradius.org] instead? It would seem to me that it would be better just to have a good authentication protocol and real security rather than just splatter crap all over the radio instead.
  • If you actually download it and look at it, you'll realize it's just a Perl script. Basically what it does is configure your laptop to be a real, functioning, access point. Every quarter second it reconfigures the card with a random MAC address and one of a handful of well-known SSID's such a "tsunami" and "linksys". Which means if you run this near any poor sap who happened to leave his card in it's default configuration, they'll be screwed as they continuously associate with your non-functioning access point.

    Basically, I can't imagine this being effective at all against war-driving. But I can imagine it being quite effective as a DoS tool. Imagine setting it up with the SSID that Starbucks uses and walking into one of their shops with this. You could have half the customers futily trying to connect to the legitimate service but getting your non-connected and continously resetting "AP" instead. It would be easy enough for this "tool" to configure the card so that clients couldn't accidentally connect to it, by enabling WEP or MAC filtering or whatever. But it doesn't do that, or even try to. I understand it's version 0.2, but at this point I think it should be filed under "trojan horse" or "skript kiddie" given that it'll easily screw up legitimate users while doing basically nothing to protect you from any crackers around.
  • I thought 802.11b was covered under Part 15 of the FCC rules. Doesn't this violate them by purposely generating interference?
  • Ok, a flaimbait subject, but get off your horse. It is a tool for FUN. Personally, I plan on using it to cause wardrivers to drive off 128 as their laptop goes bonkers in the front seat (128 is a main commuter parking lot around Boston for those not lucky enough to live there). Should be FUN!
  • As has been pointed out in other replies to this story:

    it's easy to sniff for data traffic and thus ignore the fake access points,

    this is a useful DoS tool more than a way of securing networks.

    Seems to me that as long as network admins, users or Jo-average-computer-at-home-user keeps thinking of 802.11 kit as a "alternative to wires", we'll be stuck with all the security problems. Wireless = broadcast. That will inevitably involve sending your data out to anyone who cares to set up an antenna and kit to recieve it. You trade the convenience of not having to run wires for the insecurity of broadcasting your bits to the world. Anyway, given that this unpleasantly insecure technology is spreading worldwide, it's interesting to see this article at CNet [com.com] about small, cheap 802.11 chipsets destined for set-top boxes. I contentedly predict that in a couple of years there'll be scares about wardrivers sniffing what people are watching on their wireless TVs :) Anna B

  • This might slow down wireless intruders, but not stop them ... ... Now if we where to come up with a package that makes a computer pretend it was an open relay we would be set.

    Imagine a BeoWolf cluster of these ;-) A spammer finds what he thinks is a open relay and all it does is send his junk to /dev/null.

    If everyone did this, we would raise the cost of spamming. It will not stop spammers, but it will make them have to check if the relay is actually working by spamming themselves. Nice little breadcrumb trail, no more bulk sending blind ...


  • We should stop this attitude in its tracks, it is a selfish and irresponsible waste of bandwidth.

    1) WarChalking &| WarDriving are not crimes, the bands used by 802.11 are *public airspace* they belong to *everyone* not *anyone*.

    2) The vast majority of 802.11 access points are still expermental and like the early days of the Web are *supposed* to be *free* to use by responsible early adopters.

    3) If your AP is not intended for public use, it is it's owners responsibility to secure it.
    • 1) WarChalking &| WarDriving are not crimes, the bands used by 802.11 are *public airspace* they belong to *everyone* not *anyone*.


      Just because something is public does not mean that rules do not apply to this public space. A park is a public space but there are rules about how you can use it, the unlicensed spectrum used by 802.11b is available for anyone to use but you are still required to follow FCC regulations regarding how you operate within this spectrum. There are rules that dictate how your wireless card operates, how much power it can put into it's signal, etc.


      In fact, it might be wise of you to consider this in terms of another user of this particular segment of the spectrum -- cordless phones operating at 2.4 GHz. The signal goes out over the same unlicensed spectrum band, but if you were to create a base station which prevented your neighbors from using their cordless phone handsets (even if it was accidental) you could be fined for violating the FCC rules regarding this slice of the spectrum. If you were to monitor and record a transmission between the base station and remote node you would be breaking the law. If you created a phone handset that masqueraded as your neighbors handset and used his phone base station (and phone line) for your calls you would be breaking the law. Both offenses can bring stiff fines and jail terms, something that aggressive wardrivers and 802.11b access point "borrowers" might want to keep in mind...


      • You seem to be missunderstanding my position. I am AGAINST this tool.

        You also seem to be making incorrect assumptions about what WarChalking &| WarDriving are about, it is no more about cracking than hacking is. The majority of people doing these are the very people trying to develop invovative uses of the technology.

        I suggest your persue this site: http://www.wardrivingisnotacrime.com/

        I agree. Though the author of this tool clearly does not. It is essentially an area denial of service attack for 802.11, filling the spectrum with invalid SSID's. This is akin to seeding local DNS servers with invalid domains, are worse hijacking popular domains. I am sure that the FCC would consider that abuse. I know the UK's Radio Communication Agency would.

        but if you were to create a base station which prevented your neighbors from using [...]

        I am not doing that, though anybody using this tool would be.

    • This tool is essentially conducting an Area DOS attack against peer 802.11 services.
