Security expert Joshua Saxe warns the industry is sleeping on catastrophic AI-driven cyber risk. Recent cases: an agentic campaign compromised 100 businesses and stole 600,000 credit cards with minimal human involvement at $25 in token costs per successful target; Hacktron used Claude to exploit a blind buffer-overflow RCE to access OpenAI's monorepo; newly discovered vulnerabilities are exploding. He expects attack/defense equilibrium for limited goals like espionage and ransomware, but worries about maximalist or nihilistic attackers.
