This illustrates how barriers to the use of AI in relatively autonomous cyber workflows are rapidly coming down, and highlights the importance of security fundamentals like promptly patching known vulnerabilities. Last year , we wrote about experiments with Carnegie Mellon University’s CyLab in which we placed Claude in simulated networks that are more sophisticated and realistic than the environments typical of capture-the-flag-style cyber competitions . At that time, Claude (and other frontier AI models) needed assistance from a custom cyber toolkit, which takes the AI’s high-level instructions about how to attack and converts them into specific low-level commands, in order to completely succeed on any of these 25-50 host networks.
