AI agents power growing wave of cyberattacks, with successful reaches costing just $50
fortune · reddit · 2026-10-22
Fortune reports that experts see a growing wave of AI-powered cyberattacks. CSET's Jessica Ji says models have "gotten meaningfully better" at coding and agentic tool use, dramatically boosting cybersecurity-relevant capabilities. UIUC's Varun Chandrasekaran notes LLM agents run around the clock at "a fraction of the cost of human attackers" — as low as $50 per successful reach — fundamentally changing the economics of exploitation. Open-weight models give attackers cheap, capable alternatives to closed models. The piece ties into Dario Amodei's warnings that open models may need government distribution restrictions to prevent devastating cyberattacks.
