History

And now...

For the Good Stuff

IoT Security

or, the Lack There-of

LiFX Bulb Leaks

  • Discovered mid 2014
  • Leaked
    • WiFi SSIDs and Passwords
    • User credentials
  • Firmware has since been updated

Marai Botnet

  • October 21, 2016
  • Targeted Dyn (Domain Name Service)
  • Effected Twitter, Github, Box, The Verge, Playstation Network
  • Devices Infected
    • Routers
    • IP Web Cameras
  • https://github.com/jgamblin/Mirai-Source-Code

Hue Worm

  • November, 2016
  • Weizmann Institute of Science, Israel 
  • Proof of Concept for Zigbee protocol
  • Researchers flickered lights on an off
  • Who cares about lights flickering?
    • Epileptics
  • They were able to access the 2.4Ghz test mode and interfere with nearby WiFi networks

Leet Botnet

  • December 21, 2016
  • Targeted Imperva (Cyber Security Company)
  • First Wave: 400 Gbps, 20 minutes
  • Second Wave: 650 Gbps, 17 minutes

Why??

Device Manufacturers

The Users

Minimizing Risk

Say no to WiFi IoT

PROS

  • Attackers must be located physically near your devices
  • Wired protocols require attackers to be physically plugged in to your house
  • No app to set up the device

CONS

  • RF protocols are still vulnerable to attacks
  • Requires a hub or special antennae
  • No app to set up the device

But, I need my WiFi Iot

  • Firewall
    • OpenWRT, DD-WRT, PFSense
    • Block ALL traffic in or out
    • Explicitly allow only necessary
      • Ports
      • Source/Destination IPs
  • VLAN or Separate Network
    • Infected devices are isolated
    • No sensitive data to get
  • Do nothing and hope for the best

      for sensor in self.split_device_list(self.args["sensor"]):
        self.listen_state(self.state_change, sensor)
    else:
      self.listen_state(self.motion, "binary_sensor")   
    
  def state_change(self, entity, attribute, old, new, kwargs):
    if new == "on" or new == "open":
      state = "open"
    else:
      state = "closed"
