Because the same WiFi connection they use on their rifles to foist off video onto an iPad can be used to seriously mess with the aiming system of their wiz-bang rifle.
The married hacker couple have developed a set of techniques that could allow an attacker to compromise the rifle via its Wi-Fi connection and exploit vulnerabilities in its software. Their tricks can change variables in the scope’s calculations that make the rifle inexplicably miss its target, permanently disable the scope’s computer, or even prevent the gun from firing. In a demonstration for WIRED (shown in the video above), the researchers were able to dial in their changes to the scope’s targeting system so precisely that they could cause a bullet to hit a bullseye of the hacker’s choosing rather than the one chosen by the shooter.
That’s… not good, and further proof that anything that can be used to push data out can be used as a way to force data in. Security and safety should extend to your gadgets and gear, not just your firearms.
