We've seen this problem numerous times when AI bots were fed prompts via web pages or PDFs they read. Now, academics have shown that self-driving cars and autonomous drones will follow illicit instructions that have been written onto road signs. In a new class of attack on AI systems, troublemakers can carry out these environmental indirect prompt injection attacks to hijack decision-making processes. Potential consequences include self-driving cars proceeding…
