Abstract: Over the past decade, an increasing number of systems and devices have gained Internet connectivity and been enhanced with sensing capabilities and AI. While these advancements have created a world of smarter, more automated, and highly connected devices, they have also introduced significant security and privacy challenges that cannot be effectively addressed with traditional countermeasures.
In the first part of this talk, we will explore the security and privacy concerns of cyber-physical systems. Specifically, we will examine new threats that have emerged with the deployment of technologies like drones and Teslas in real-world environments. Our discussion will highlight methods for detecting intrusive drone filming and securing Teslas against time-domain adversarial attacks.
The second part of the talk focuses on the challenges posed by the coexistence of functional devices with limited computational power (that do not adhere to Moore’s law) alongside sensors with ever-increasing sampling rates. We will explore how threats such as cryptanalysis and speech eavesdropping—previously accessible only to well-resourced adversaries—can now be executed by ordinary attackers using readily available hardware like photodiodes and video cameras. These attacks leverage optical traces or video footage from a device’s power LED to extract sensitive information.
Finally, in the last part of the talk, we will address the emerging need to secure GenAI-powered applications against a new category of threats we call Promptware. This threat highlights the evolving landscape of vulnerabilities introduced by generative AI systems.
