What the Future Holds: Purgatory??
So what does the future hold? The use of microcontrollers and devices like the Teensy represents the next evolution in the race between IT security and the tools that attempt to circumvent it. It seems clear that the use of microcontrollers such as the Teensy as attack platforms is just in its infancy, and we will see significant growth and changes in this area in the coming years.
I read once that "In order to defend against a threat, we must first understand it." This next evolution of USB-based attacks will challenge IT security professionals to better understand the inner workings of USB attacks and develop crafty solutions for mitigating the threats.
