Vals tested open‑weight model DeepSeek on simulated corporate networks and found its hacking performance, achieving 73% task completion, was close to that of OpenAI’s closed frontier model Daybreak, which completed 81%.

Why it matters

DeepSeek approaches closed‑model hacking performance on corporate network simulations; monitor these capabilities as competitors may embed similar attack features.
