Israeli Cronus “Imitates the way computer hackers think”

I wonder if there are pattern-based behavior analysis and statistics on machine-based penetration testing in comparison to human penetration tester habits and results. I'm generally suspicious of AI and even more so of machine-based automation that works without a traditional AI engine. The suspicion is not a commentary on AI itself, but my own failure to anticipate (occasionally) an AI's next move since modern AI has moved far beyond imitation of "human" models and can be quite cagey :-)
