Distillation Defenses Easily Break After Reinforcement Learning

- What happened
- Researchers show that distillation defenses against language model theft fail when attackers apply reinforcement learning after the initial distillation step.
- Why it matters
- Security engineers protecting closed-source LLM APIs should care, as current defense evaluations may underestimate real-world attack effectiveness.
- Watch out
- The paper assumes attackers have API access and time for post-distillation training, which may not reflect all deployment scenarios or threat models.
