  1. Attack of the Killer Void:Managing wireless computing

  2. This is funny…

  3. Wireless Timeline - • EARLY DAYS • Thomas Edison and other early inventors theorized on radio frequency transmissions and their capabilities. • 1942 - Composer/pianist George Antheil and actress HedyLamarr patent a frequency-hopping radio encryption technique (later called spread-spectrum technology) and donate it to the U.S. Navy, which classifies it but finds it too UNRELIABLE for use in WWII.

  4. Timeline continued… • Other junk goes in here….blah blah blah blah • FTC opens the spectrum…blah blah blah • 1999 – 802.11# ratified making client networks a possibility.

  5. Where have we gone… • Hotspots – Starbucks started putting these in back in 2001 – now they are everywhere… • Smartphones with wifi sharing • Bluetooth headsets • Wireless keyboards and mice • Mi-Fi devices from any carrier

  6. Another funny…

  7. Attacks… • Google search – Hacking wireless – • You’ll find lots of tools: • Asleap - Cisco LEAP AttackBluecrypt - Implementation of the Bluetooth CiphersCowpatty - Attacking WPA/WPA2-PSK Exchangeseapmd5pass - Attacking EAP-MD5 networksfile2air - 802.11 packet injection utilityFreeRADIUS-WPE - Attacking PEAP and other 802.1X EAP typeswlan2eth - Converting wireless packet captures to Ethernet format Aircrack-ng – key cracking program John-the-ripper – password ripper Kismet – See local SSID Wireshark – network traffic sniffer Airpwn – I own your network adapter Ettercap – sniffer/interceptor/logger Cain and Abel – password cracking/recovery TCPDump – packet interceptor Dsniff – displays pictures being transmitted over unencrypted wireless Netstumbler – wireless network detection Ntop – network utilization tool NGREP – network packet analyzer (Network Grep) Etherape – graphical network monitor Kismac – kismet for a mac Metasploit – point and click network exploit tool FakeAP – generate a lot of fake SSID’s.

  8. All in one - • Backtrack – BT4. Hackers tools all in one handy self booting disc. • www.remote-exploit.org • Hacking Keyboards and such: Keykeriki v2

  9. Wifi Keyboard

  10. Bluetooth problems • Go do a Google search on bluetooth eavesdropping – • Spread spectrum frequency hopping (good and bad)

  11. What can a hacker find…

  12. More information

  13. Another Funny

  14. New Wireless Standards • 802.11n • Requires the use of WPA2 with AES encryption • Provides Theoretical speeds up the 600 Mbits • Actual speeds have been achieved on our system at 125 Mbits.

  15. Managing your Networks • Dsniff – captures SSIDS • Use a VPN • Use WPA2 – with AES • Patch often and use a firewall (patch routers/wifi devices too) • http://wigle.net/gps/gps//Stat – top 1000 SSIDS

  16. Wireless uses Radio Frequency • 2.4 Ghz wifi spectrum • 5 Ghz wifi spectrum

  17. Clean Spectrum

  18. Dirty Spectrum w/ Bluetooth

  19. Real Life Problems – MI-FI

  20. Solutions to help us all!!! • Use standard non-overlapping channels – 1,6,11 • Use a tool like Inssider to find your best channel option (2.4 Ghz band) • Pass the word around to neighbors if you see a problem • Keep your signal strength as low as possible to share the bandwidth

  21. And when we die…

  22. Questions: • NOC – 801-587-1300 • Helpdesk Trouble Tickets
