DEF CON 23 - Fiber Optic Tapping

DEF CON 23

I’m incredibly honored to be part of DEFCON’s first-ever Demo Lab. My submission focuses on tapping fiber optic cables using a method called "bending." My setup will include:

  • (2) Raspberry Pi 2
  • Fiber Optic Clip-On Coupler
  • (3) Fiber Media Converters
  • SC->SC Duplex MultiMode 62.5/125 Fiber Optic Cable
  • SC->SC Duplex SingleMode 8.3/125 Fiber Optic Cable
  • FC->SC Fiber Optic Coupler

The demo will take about 15 minutes to set up and another 15 to tear down, leaving me on display from 12:15 PM to 1:45 PM on Saturday, August 8th. I’ll demonstrate:

  • How to set up the tap.
  • An explanation of how it works.
  • How this setup could be concealed in a data center.
  • Tentatively, how to access the inner fiber and cladding without stripping anything.

Looking forward to seeing everyone there!
