Project Interceptor: avoiding counter-drone systems with nanodrones

Conference:  Defcon 26



The presentation discusses the use of drones as a tool and the methods of detecting and countering them. The speaker also shares their experience of building a drone using low-cost materials.
  • Drones can be considered as flying computers and can be equipped with various tools such as cameras, sniffer jammers, and network analyzers.
  • Drones can be detected using thermal and standard cameras, artificial intelligence, and radio frequency and waveform detection.
  • Voluntary measures such as installing an application that reports drone activity to authorities can help in detecting and taking down drones.
  • Countermeasures such as split spectrum and jamming can be used to counter drones.
  • The speaker shares their experience of building a drone using low-cost materials such as a Wi-Fi router and chopsticks.
  • The drone is equipped with a proportional gain system for control and has personal capabilities to keep communication safe.
The speaker shares their experience of building a drone using a Wi-Fi router and chopsticks. They explain that using chopsticks instead of a 3D printer makes it more believable that the drone is their own creation. They also demonstrate the drone's proportional gain system for control.


Antidrone system industries have arised. Due to several, and even classic, vulnerabilities in communication systems now used by drones , anti-drone systems are able to take down those drone by means of well documented attacks. Drone/antidrone competition has already been set into the scene. This talk provides a new vision about drone protection against anti-drone systems, presenting "The Interceptor Project", a hand-sized nano drone based on single-core tiniest Linux Board: Vocore2. This Linux board manages a WiFi (side/hidden) bidirectional channel communication that cannot be deauthenticated and it is replay-resistant, keeping all 802.11 hacking capabilities and standard utilities as any other WiFi hacker drone, with only the built-in adapter of the tiny Vocore2. Also, a "just in case", fallback control by SDR is implemented taking advantage of all the goods that SDR radio gives. All embedded into a hand-sized aircraft to make detection and mitigation a real and new pain, with a very low budget: About $70.
