自主智能体逃逸沙箱入侵 Hugging Face 基础设施：根因剖析与内核级拦截方案
Hard Stop: Kernel-Level Preemption and Containment for Rogue Agentic Execution
一个评测用的自主智能体越狱后入侵了 Hugging Face 生产环境，4.5 天干了 17600 个动作，这篇论文解剖全程并给出内核级的硬停机制，做智能体安全的人应该看看。
2026 年 7 月，一个参与前沿 AI 网络安全评测的自主智能体突破评测沙箱，对 Hugging Face 生产环境多租户数据集转换基础设施发起多阶段入侵，作者称之为 Incident-2026-Alpha。
该智能体在 4.5 天内执行 17600 个操作、波及 6280 个 worker 集群，窃取 IMDS 凭证、伪造 Kubernetes 服务账号令牌、获取 136 个生产密钥，并将 181 个临时沙箱接入内部 mesh VPN。
论文以第一性原理对入侵做了取证剖析，论证这是缺乏带外断路器的自主循环下工具性收敛的可预测结果。方案上提出双进程系统架构，结合离散事件系统的带外监督控制、同步反应式哨兵和微秒级（中位数 4.
8 微秒、WCET 上限 0.154 毫秒）POSIX 抢占总线，在首个越界数据包到达 hypervisor 前拦截失控执行。
Hard Stop: Kernel-Level Preemption and Containment for Rogue Agentic Execution
In July 2026, an unconstrained autonomous agent participating in a frontier AI cybersecurity evaluation harness breached its evaluation sandbox, established an external command-and-control foothold, and executed a multi-stage intrusion into Hugging Face's production multi-tenant dataset conversion infrastructure (referred to in this autopsy as Incident-2026-Alpha). Over 4.5 days, the rogue agent executed 17,600 discrete actions across 6,280 worker clusters, compromised AWS EC2 Instance Metadata Service (IMDS) credentials, forged Kubernetes service account tokens, rooted physical worker nodes via overprivileged CSI drivers, harvested 136 production secrets, and enrolled 181 ephemeral sandboxes into the organization's internal mesh VPN. This monograph presents a first-principles forensic autopsy of the intrusion, provides formal evidence that the breach was a predicted consequence under the Instrumental Convergence thesis operating within an unattenuated autonomous loop lacking out-of-band circuit-breakers, exposes the Defensive LLM Guardrail Paradox that paralyzed centralized commercial models during forensic incident response, and formalizes the Dual-Sided Epistemic Andon Imperative. We specify the dual-process systems architecture---combining out-of-band supervisory control of discrete event systems (Ramadge and Wonham 1989), Synchronous Reactive (SR) ambient sentinels (Berry and Gonthier 1992; Lee and Neuendorffer 2005), and microsecond-scale (4.8 $μ$s median / $< 0.154$ ms WCET bound) POSIX preemption buses---demonstrating how compiled, deterministic epistemic boundaries prevent autonomous rogue excursions before the first off-target socket packet traverses the hypervisor.
