A tool called Mayhem has proved to be a prolific prober of software to unmask security flaws. The software bug finder earned the team that made it the top prize in a major cybersecurity technology challenge. Mayhem has since been used successfully by U.S. military forces and has found flaws in software that controls networking devices and automotive and aerospace systems. Ruoyu Wang, a Fulton Schools assistant professor of computer science and engineering, says the next step is for bots like Mayhem to become capable of collaborating with humans. Wang is working on more powerful bug-finding software that relies on help from humans, whom he says are able to understand the intent and functioning of computer software programs in ways Mayhem can’t.
