The article explores how Artificial Intelligence hackers can attack computer systems and how human hackers can defend against them. The researchers created a game board that represents cyber attacks and defenses, using an AI algorithm to map moves in the game to actions in the cyber world. They found that well-trained AI hackers are very difficult for humans to beat unless their attack strategies are known beforehand. Different AI algorithms behave like different hacker personalities, showing how hackers with different skills would exploit or defend against network vulnerabilities.
