A drone powered by artificial intelligence crashes in a remote field, destroying its onboard computer and leaving investigators without the data needed to determine whether a cyberattack caused the failure.Researchers at Georgia Tech say they have developed a system to help answer that question.Known as FIRA, the tool analyzes drone crashes to determine whether they were caused by tampered machine-learning (ML) models. The team will present its findings at the 35th USENIX Security Symposium in August.
