testing methods had previously missed, highlighting a significant gap in traditional vulnerability research approaches. This matters because unknown vulnerabilities represent an invisible attack surface — threat actors with access to similar AI capabilities could discover and exploit these flaws before defenders are even aware they exist. The fact that GPT-6 Cyber also demonstrated working exploit development for a critical Brotli vulnerability underscores that AI is now accelerating the arms race between attackers and defenders. Organizations relying solely on periodic manual audits or legacy scanning tools are increasingly outpaced by AI-augmented threat actors.
