Detecting 802.11 Discovery Apps

Posted by Hemos on from the looking-at-the-backdoor dept.

Joshua Wright writes "I have written a white paper on detecting 802.11 Wireless LAN Network Discovery applications. Wireless LAN discovery through the use of applications such as NetStumbler, DStumbler, Wellenreiter and others is an increasingly popular technique for network penetration. The discovery of a wireless LAN might be used for seemingly innocuous Internet access, or to be used as a "backdoor" into a network to stage an attack. This paper reviews some of the tactics used in wireless LAN network discovery and attempts to identify some of the fingerprints left by wireless LAN discovery applications, focusing on the MAC and LLC layers. This fingerprint information can then be incorporated into intrusion detection tools capable of analyzing data-link layer traffic. "

      That's because you are flat out penetrating her network through the back door. Do some probing first man. You have to find out if there are any ports or services receptive to your connection before you attempt to dive right in and exploit any weaknesses.

      That's because she wants you to spend time with her, not your buddies.

      Dave's relationship rule #27:

      "When you find a woman who reacts positivly to the suggestion of 'backdoor penetration', seriously consider marriage"

      rules to live by.

    God damn, I love a good arms race.

    Are you a coder? Need work? Get involved at the beginning of an arms race such as this one. Employment for years and years. Get involved early enough, and soon you will be an "expert".

    Of course, there are more employent opportunities on the defensive side of the race, while the more fun side is the offense.

      thats because you're not trying to come through the back door with an OC-192.

  4. My Whitepaper by suwain_2 · · Score: 5, Funny

    That's funny, I'm working on a similar whitepaper: Detecting 802.11 Detector Detectors, to detect people trying to detect people trying to detect 802.11 networks. Including is some sample code to detect the detector detectors, but it seems to get into a nasty infinite loop, and I can't figure out why.
