Essential Insights Current Claude AI models can now perform complex, multi-stage cyberattacks on networks with minimal tools, indicating rapid reduction in barriers to autonomous cyber operations. The updated Claude Sonnet 4.5 successfully exfiltrated sensitive data from high-profile simulated breaches using only standard, open-source penetration testing tools like Kali Linux, without custom software. Sonnet 4.5 can quickly identify and exploit known vulnerabilities (CVEs) on its own, exemplified by replicating the Equifax breach using publicly available exploit code. These advancements highlight the critical need for rigorous cybersecurity practices, such as timely patching of known vulnerabilities, to defend against increasingly capable AI-driven cyberattacks.…
