English(EN) SecOPD: Mitigating Adaptive Prompt Injections by On-Policy Distillation

新的 SecOPD 方法大幅削减 AI 代理的提示注入攻击

研究人员开发了一种名为安全 On-Policy Distillation (SecOPD) 的新方法来对抗自适应提示注入,这是 AI 代理面临的关键威胁。与使用序列级反馈的先前技术不同,SecOPD 在微调期间提供令牌级反馈,使模型能够更精确地学习其输出的哪些部分不安全。这种方法显著降低了攻击成功率,经过防御的 Qwen3.6-27B 模型在面对自适应提示注入时达到了 9.0% 的 ASR,相比之前最先进的 94.0% ASR 有了显著改进。SecOPD 的安全收益也泛化到新领域,例如代理工具调用,其 ASR 为 4.7%,而 Meta-SecAlign 为 5.5%。 AI

影响 通过显著降低提示注入攻击的漏洞,增强了 AI 代理的安全性。

    SecOPD:通过 On-Policy Distillation 缓解自适应提示注入

    arXiv:2608.21500v1 Announce Type: cross Abstract: Prompt injection is listed as the \#1 threat to AI agents. When an agent accesses external data from websites, files, or emails, an attacker may inject a prompt into the data, saying, "Ignore all prior instructions and perform ." …
