Windows 7 Can Create Rogue Wi-Fi Access Point 123

Posted by timothy
from the feature-not-bug dept.
alphadogg writes "Windows 7 contains a 'SoftAP' feature, also called 'virtual Wi-Fi,' that allows a PC to function simultaneously as a Wi-Fi client and as an access point to which other Wi-Fi-capable devices can connect. The capability is handy when users want to share music and play interactive games. But it also can allow on-site visitors and parking-lot hackers to piggyback onto the user's laptop and 'ghost ride' into a corporate network unnoticed." While this means a bit more policing for networks meant to be locked down, it sounds like a good thing overall. Linux users, meanwhile, have had kernel support (since 2.6.26) for 802.11s mesh networking, as well as Host AP support for certain chipsets.

      Actually, can someone explain to me what the real difference is between "master mode" and AdHoc or mesh networks?

      Why is it that only a few chipsets can "do" proper full-blown "master mode" (ie be an Access Point), and yet other chipsets can be used as AdHoc or mesh? I mean - what's the fundamental difference? I've been through this with Linux systems and can't understand why I can't just grab any WLAN card, bring up the interface and whack a DHCP server on it - why doesn't that work for them all?

        "Master mode" means that your computer works as a central access point, other computers use it to relay the data.

        "Ad-hoc" is a special mode for masterless networks, but it allows to connect only two computers (in essence, wireless channel becomes an analog of good old Ethernet cable).

        "Mesh mode" is 'ad hoc' on steroids, it allows any number of computers to connect and uses dynamic routing.

                While all that you say is true, from what I understand (and I could be wrong) Windows doesn't have this activated by default, you have to turn it on. Any Linux install has the capacity to be an unsecured server, just hanging out there in the breeze for anybody to infect. We don't say that is a bad thing though, do we?

                MSFT added a feature. Now this feature, which could be very handy for those that need to share files or want to set up a quick gaming LAN, can be misused and cause security problems. That a handy OS feature can be misused and cause a security problem applies to just about every single program that can access the net. As for corporations? Well if they pay bottom dollar and and only hire the cheapest most underpaid flunky they can get to save a few buck, and they get pwned, I should care....why exactly? Good things cost good money, the same goes for people. if a company is so badly run that this single feature can completely turn their network security into a house of cards I think they have bigger problems, don't you agree?

                In the end the whole TFA felt to me like creating a bogeyman for them to defeat with their super neato security product. But you and I know security doesn't come in a can. it isn't some product you can just slap on the network and all is well. Security is an ongoing process, that must be planned, implemented, and adapt with changing conditions. And that all needs competent staff to implement correctly. in the end companies that go for bandaids like the TFAs product (which may be good for all I know) will end up failing miserably when some fool on their network does something stupid. This feature won't kill any networks, piss poor admins and security policies that don't exist will take care of that all by themselves, thanks.

    This doesn't seem like any more of a problem than someone jacking in to an empty ethernet port on your network, except that a) they can do it from outside the building wirelessly and b) any special software used by the 7 user to access the network could potentially helpfully forward packets from others, but that would probably be a fault of the software not checking the origin IP on packets...

    Anyways the fix is simple. Require authentication for all network resources. Windows enterprise solutions are set up like this by default and do it transparently using Windows login credentials. An intruder on your network would be unable to access anything. There is the LITTLE issue of exploits, so you can either batten down the hatches as much as you can and continually scan for suspicious network traffic, or you can try an alternate solution which may work better (a combination of both would be best):

    For complete security, IT could notify all employees that use of this feature is not permitted. On corporate machines it could be disabled or removed or steps taken to block access, but you must assume users are clever enough to get it working (not to mention booting from a LiveCD bypasses every protection known, except complete Windows software compatibility. Someone did mention Linux software that did this though, and my brother's WiFi card supposedly does it too with a special included application.). IT could also compromise and allow users to use it if it is properly configured, with clear steps outlining how to check if this is the case. However either way, severe penalties (starting with being kicked off the network until you have resolved the problem) would be issued for having an open access point. IT would have to periodically stage their own "attacks" to look for such hotspots and attempt to connect, and then lock the user out of the network if they are able to access the user's machine anonymously (ie folder shares with company files) or the network.

    OK so it's a long winded solution but basically: The problem isn't new, lock down systems with authentication best you can, routinely scan for hotspots and penalize users that put them up.

    Disclaimer: I am not a security expert but I like to think I've picked up a few things.

      You are misunderstanding the problem. The PC running this feature becomes a router bridging their local and probably unauthenticated network with whatever secure network they are already connected to. Add network connection sharing to the mix and you have a security hole regardless of how 'locked down' the original network is. How big a problem this is will depend on the implementation and I haven't seen it.

      Where I come from, deliberately bypassing network security is a one-strike-and-you're-out termination offense.

        Can you stop by and have a conversation with my HR department? The finance department seems to be stripping security out of the network under the guise of "controlling costs", yet I can't get an HR policy to make it a termination worthy offense to bypass the few controls that are left.

      Anyways the fix is simple

      Yes, give cisco sh*tloads of money. It's just like the easy solution with corrosion, coat everything in gold. There are better things to do with budgets.
      I had an idiot bring in his own wireless access point instead of borrowing any of the spare 8 port switches and a 2 metre cable - and that idiot turned on dhcpd and took quite a few people off the network. The only real way to stop that is firewalls all over the place or firewalls built into all the switches. Effectively you tel

      This doesn't seem like any more of a problem than someone jacking in to an empty ethernet port on your network

      Unused ports are left unusable. Assigned to a 'quarantine VLAN' which has only an IDS on it designed to set off alarms if anything sends traffic to it.

      Ports that are in use, have port security enabled with sticky MAC address, and thus an alarm is also set off on violation.

      but you must assume users are clever enough to get it working (not to mention booting from a LiveCD bypasses every prot

      I didn't RTFA, but I guess the problem is user will see an AP with the same SSID that user used to be connecting...and tricked into connecting it but that's actually a rouge one? Even without Win 7, I could do it with a $50 SOHO Wireless Router!...

      The parent is right - If your network is that sensitive, please turn on Group Policy to requires IPSec encryption on both ends, and requires Proxy (say MS ISA) to go to the Internet. Then the rouge AP doesn't really matter.

  • I need to play with this feature on my W7 laptop, I wonder how far the reach is on this and how well I could daisy chain this, just out of curiosity more than anything useful.

  • Didn't we already go through this with Ad Hoc networks on the original version of Win XP? The 'Free Public Wifi' SSID is still around today thanks to this poorly conceived 'convenience' and it was a nightmare for anyone trying to manage a secure wireless network. I think time will show this feature not being worth the trouble it causes.
  • What you attempt with 'ghost ride' is better communicated and less retarded with one of the following phrases:

    * piggy-backing
    * covert channel
    * out-of-band

    There's no applicable analogy with 'ghost ride' to communicate what you're trying to describe. Don't try to introduce new lingo. You might as well call it 'Dog sledding' as it has just as much in common with covert channels as 'ghost riding' does.

  • Seriously! That is exactly what I wanted to do a few months ago, but it seems I can't with my WiFi Link 5300. Hostap seems to be for Prism chipsets. Easily creating an AP to share files or to play with neighbors [ex-parrot.com] was one of the bonuses I expected from my switch to Ubuntu. What is going on? Is Windows now becoming the fun OS for geeks and Linux the boring Desktop for the average users?

    • by mrbene (1380531)
      Is the WiFi Link 5300 Intel based? A recent blog entry [blogspot.com] from Connectify indicates that there may be issues with those drivers - at least for Windows. Mind you, if Intel has outstanding issue in the Windows drivers, it's possible that it's a problem in Linux version as well.
      • by cbhacking (979169)

        Lacking more info, I'm going to venture a guess that yes, the 5300 the GP mentions is the Intel Pro Wireless 5300 chipset (802.11abgn, and generally pretty darn good). The Linux drivers for it are open-source, but that doesn't necessarily mean bug-free or that all features are available. It does mean you could try to get it working yourself if you want, though. I have one such chipset myself, and while I've never tried to make it act as an AP, it would be neat to be able to do so.

        On a side note, are there a

        Yes, it's the Intel WiFi Link 5300 (in a Thinkpad), using the iwlagn driver (in Ubuntu 9.04). Not sure if it's because of the chipset, the driver or their combination, but it doesn't support master mode:

        # iwconfig wlan0 mode master
        Error for wireless request "Set Mode" (8B06) :
                SET failed on device wlan0 ; Invalid argument.

    • by Xabraxas (654195)
      MAC802.11 supports creating an AP and since the standard intel wireless driver is MAC802.11 based you should be able to do this easily with the aircrack-ng suite.

    Is there an article on Network World that condemns Linux for having this ability? Well I did find this [networkworld.com] when I searched for Linux and HostAP. Don't see anything in the article mentioned that it too, could be a security risk if used incorrectly. It's not called Beware the
  • Aruba Networks has support for detection and elimination of rogue AP's.

    An important network that does not have wireless intrusion detection and control is definitely not protected well.

    However, a proper Aruba deployment with AP's and a mobility controller can and do identify, mark, and shut down rogue APs and ad-hoc networks, as well as wireless bridges.

    I am not terribly worried.

  • If this article is accurate, we'll see the beginnings of real ad-hoc mesh networks starting in 2010. This feature has the potential for allowing massive ad-hoc networks. Awesome. ISP's are going to pee themselves. Awesome.

      Nah, they'll start charging by the gigabyte, so if you hook a computer up to internet and 2000 machines end up routing through it downloading Wolverine, you'll have to pay for 1.4 TB of traffic ($1400 at 1 dollar per gigabyte). Hopefully we'll get rid of ISPs entirely sooner or later, also fixing the net neutrality problem, the throttling problem and kicking the RIAA a few extra times but it'll take at least a decade.

  • Is this just the Ad-Hoc network option that can be setup in the network and sharing center, or is it something else?
