Attack Methodology

SLIDE 14

Dolphin Attack Major Contributions

  • Attackers can use inaudible sounds (>20kHz) to activate and control

voice controllable systems such as cell phones, home entertainment systems, vehicles, etc.

  • The attack is sneaky in nature. Device owners may not be aware that

they are being attacked due to the remote distance and inaudible sounds that the attack utilizes.

Dolphin Attack…?

What does this have to do with Dolphins?

Motivation

  • Eaves Dropping (Leak Personal Data, Authentication By-Pass, etc.)
  • “Sneaky” Attack
  • Defeat the “Air-Gap”
  • Drive-By Attack

Threat Model

  • No Target Device Access
  • No Owner Interaction
  • Inaudible
