Leaky cybersecurity guardrails in frontier models favor attackers, researcher argues
Michael_D_Moor · x · 2026-10-19
The author argues that imperfectly blocking cybersecurity use in frontier models directly helps attackers: if the model rejects 99.9% of cybersecurity-related prompts, attackers can prepare offline and sample over thousands of attempts to construct a few working attacks through the leaky barrier — while defenders must act in the heat of the moment and can't use the same frontier model (blocked at the same high rate) to iterate within a few attempts. Leaky guardrails thus create an asymmetry that disadvantages the defending party.
