Presentation Transcript

  1. Wireless Weaponry The Shmoo Group

  2. Intro a.k.a. WTF is Shmoo? • Howdy! • Who’s who up here? • What the hell are we gabbing about? • “Who’s Shmoo?” takes too long to answer. • Enjoy http://www.shmoo.com • Let’s get rolling…

  3. You vs The Industry • Security terminology that's confusing... • WEP, WPA, 802.1x, EAP, TLS, 802.11i, TKIP, RSN • Security OFF by default... • Security gets in the way of Plug n' Play, doesn't it? • Security implemented poorly... • Newsflash: WEP sucks. • Security by obscurity... • Disable SSID broadcast? Puh-LEEZE. MAC filters? Puh-LEEZE. • Out of the box, wireless security is not easy, it is not on, it does not work, and it is a sham.

  4. You vs Your Users • Your users want to use wireless... NOW. • If you don't plug in an access point, they WILL. • Your users don't WANT security. • Don't you REMEMBER? “They want to use wireless... NOW.” • Your users are 0wn3d. • Worm traffic on a wireless network is a wonder to behold. • Your users aren't YOUR users anymore. • They're MINE. Via rogue AP. And they don't even know it. • Your users are... well, USERS.

  5. You vs The Technology • The packets are in the air. • Pop some popcorn, turn on the baby monitor, or answer your phone and say “bye-bye” to your packets. • Too many packets cause problems. Duh. • The CERT “down under” just figured this out a couple months ago! • One man's packets are another man's noise. • Channels, channels everywhere, but only THREE can blink. • Some packets have more authority than others... • 802.11 management = When bad-guys “talk”, EVERYbody “listens”. • You can not put a leash on your packets. • They look just as good from the parking lot as they do in the office. • Darn those pesky packets!

  6. You vs The Future • EVERY wireless security mechanism to date has had a flaw discovered within a few years of release... or a few months, in some cases. • But don't worry, the next fix is just around the corner. • Watch out for security “features” that cause denial-of-service. • Some cures may be worse than the disease. WPA, anyone? • 802.11i will not save you from yourself. • Too bad you can't use it on your existing hardware. • Too bad people can't figure out PKI on WIRED networks. • Too bad half of it is sure to be optional. Thanks, vendors! • And now for something completely different...
