Thomas Ptacek: 2025 open-weights models could hack networks

Thomas Ptacek suggests that even an open-weights model from 2025, equipped with a pentest harness, could achieve sandbox escapes and network hacking similar to what was recently observed. He implies that the surprise stems from an assumption of superior security in OpenAI's sandboxes, rather than the model's capabilities requiring a frontier-level AI. AI

IMPACT Suggests that current open-weights models may already possess capabilities for network exploitation, challenging assumptions about AI security.
