  1. Rogue Access Points Patrick Araya

  2. What is it? • Any unauthorized device that provides wireless access • Implemented using software, hardware, or a combination of both • It can be intentional or unintentionally set up

  3. Unintentional? • Employees attempting to put in their own wireless at work • Mobile hotspots from cell carriers Intentional? • Honeypot to see what people are up to on your network • Nefarious activities…

  4. Why is it a bad thing? • It’s a huge security risk! • In a corporate environment it allows unauthorized access to the network • Often they’re misconfigured and lack security features

  5. Hardware Based AP • Your everyday wireless router • Mobile hotspots • Wi-Fi Pineapple

  6. Wi-Fi Pineapple • 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

  7. Wi-Fi Pineapple Cont. • 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

  8. Software Based AP • 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

  9. Airbase-ng • 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

  10. Airbase-ng Switches • -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) • -a bssid : set Access Point MAC address • -iiface : 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

  11. Airbase-ng Bridged AP Configuration • airmon-ng start wlan0 • airbase-ng -e "Free Wifi" -c 1 -v mon0 • ifconfig at0 up brctladdbrmitm brctladdifmitm eth0 brctladdifmitm at0 ifconfig eth0 0.0.0.0 up   ifconfig at0 0.0.0.0 up dhclient3 mitm • Put wireless card in monitor mode • Create SSID on the wireless interface • Bring up the AP • Configure the bridged adapters • Profit
