Wireless Networking Security Worms Hardware

Researchers Say Wi-Fi Virus Outbreak Possible 165

alphadogg writes with a link to a NetworkWorld article about a troubling security scenario. Indiana University IT researchers are now saying that a WiFi attack intended to piggyback across unsecured access points could do serious damage in a city like Chicago or New York. By essentially brute-forcing the passwords on insecure routers, a worm-like firmware agent could be introduced to an estimated 20,000 networks in New York City alone. "Although the researchers did not develop any attack code that would be used to carry out this infection, they believe it would be possible to write code that guessed default passwords by first entering the default administrative passwords that shipped with the router, and then by trying a list of one million commonly used passwords, one after the other. They believe that 36% of passwords can be guessed using this technique."

    I'm not so familiar with Belkin, Netgear and all no-name wireless routers out there, but the newer (last year or two) Linksys WRT54G routers don't allow administrative access over the WLAN by default. You simply get an access denied page when attempting to access it. I'm kind of surprised that linksys doesn't just deny wireless connections to the administrator pages.

    Unfortunately, that means that I can no longer log in to those routers with default passwords and open up ports for myself when I'm on some stranger's network and it requires me to plug in when I need to make changes on my own networks.

    Of course, you should disable access to the administrator pages over the WLAN (or restrict it to a maintenance port if your router has one), change your administrator password (and username, if possible) and make sure you've got strong encryption with a strong password/key.

I use a MAC filter that only allows computers I SPECIFICALLY tell it to, I have disabled administrative access to the router wirelessly and changed the default login AND password, and I password protect my wireless access on top of all that. It took me about an hour (if I recall correctly) to set the router up, including flashing the DD-WRT firmware on it. But once it is done, I don't have to bother changing any more settings, aside from rotating the admin password and updated the MAC filter as needed.

          Yes, lots of hardware (especially routers) set their MAC Address in software.

          If so, how could someone get the MAC address of another computer they do not have physical access to?
          MAC Addresses are constantly being broadcast, it'd be trivial to catch one.

        • Yes, there is some way to spoof a MAC address. In Linux you can do it with a simple ifconfig command. In Windows you have to edit the registry.

          In order to find out the MAC address of another computer across wireless, you just have to snoop on the packets (use wireshark). The MAC address is right there (otherwise how would the router find it out?)

          Now if everything is encrypted with a scheme that isn't broken (WPA not WEP), then snooping becomes impossible. But if you are using WPA already, MAC filtering

      A couple of weeks ago, my network started acting very strange. My computers couldn't see each other through the LAN, and my wireless network disappeared. I figured out that the router was doing some kind of a soft reset every second; it ended up getting one of my DynDNS domains disabled due to abusively updating my domain. I couldn't reset the router with the physical button, so I replaced it with an Apple router that supports WPA2.

      Why not make the password something like a printed number on the router itself? I know it's encoded in firmware, especially with the factory reset button, but it's not too hard to say read the ID and print up corresponding stickers. They already do it for the MAC address information.

      That would require either 1. compiling a new firmware for EVERY unit, or 2. storing the password in a separate chip, which increases parts, cost, and everything else. They might be able to bypass the drawbacks of #2 by using the LAN side MAC tho, since that shouldnt be accessible via wifi for most wifi "routers" (tho a simple AP might be.. not as familiar with those), unlike the wifi MAC thats transmitted to all.

    "Scenario?" With a "worm-like software agent?" Wake me up when (a) such a firmware worm is written or (b) when someone from the security community can be a little more specific as to how such a worm could work. I remain skeptical.

  • Other than possibly create a few more zombies (and I am sure there are easier ways to do that) who cares?

    Folks with real and/or sensitive data will have a password, and likely even more security.

    Those that don't likely have little to offer any hacker or anybody else. A hacker may desire your cycles for zombified attacks, and the RIAA might like to look at your MP3 list. Maybe someone might go through the trouble of trying to data mine for identity theft, but again there are much easier ways to accomplish th

  • Oh great, so they get access to the machine. Just as if it was plugged into a DSL/cable modem line. AND???

    Cracking the password and getting network access isn't the same as getting past the firewalls, installing yourself on the machine and getting something to run you. Someone is fear mongering, or has failed to think this through.

    What happens with this virus spreads itself around, and then takes over a automated weapons manufacturing plant? I'll tell you what happens. It becomes SELF-AWARE. That's what happens. The next thing you know, we'll have governors showing up naked in deserted places and then beating up biker guys for their clothes. We have to stop this NOW!, before someone gets the bright idea of making a TV series about it.

    Aaaah!!! We're to late. Run for the hills!!



  • I don't have any practical experience with this, but theoretically, I think a virus could be created that would infect windows computers and enable internet sharing off the wireless card. It would look at the name of the existing wireless connection and then call the shared connection '+1'. Then when zombied laptops go to coffee shops, etc. they become an additional wireless access point named 'coffee shop2'. Others mistakenly connect to the internet through this spoofed access point and all their outgoing

Every nonzero finite dimensional inner product space has an orthonormal basis. It makes sense, when you don't think about it.
