Dark Reading报道Tenet在DEF CON展示的Ghostjacking研究。外部可影响的日志、告警或错误信息可能被智能体误当作操作指令,使其越过原任务范围。研究涉及多个监控与基础设施平台,提示工具返回的数据应与操作授权分开处理。相关结果来自厂商研究和受控演示,不能表述为实际客户系统已遭攻击,也不能外推为所有智能体配置都会失守。
The Hacker News 介绍研究者提出的 Agent Data Injection(ADI):攻击者操纵智能体依赖的数据字段,使其在继续执行原任务时依据错误信息采取行动,而不是直接插入新的操作指令。作者在网页操作和编码助手等受控场景中展示了错误点击、误信身份或执行记录等风险,并报告部分针对传统提示注入的防御无法同样阻断这类数据操纵。不同产品和界面设计的结果存在差异,例如随机化元素标识可限制某类点击攻击;更严格的数据来源追踪也伴随任务完成能力下降。报道基于研究者实验及访谈,不代表存在已确认的在野利用,也不能将单项防御结果泛化为全面安全。
Zenity Labs 发布研究《It's Always DNS in Claude's Sandbox: From Data Exfiltration to a Bidirectional DNS Shell》,作者为 @_d1voy,展示在 Claude 沙箱中借助 DNS 实现数据外泄,并进一步建立双向 DNS shell。转发者 @p1njc70r 称其为 DNS C2,并称赞该工作。研究的具体攻击路径、受影响版本与成功率未在转发内容中给出。

It's been a while since @_d1voy published his last work, but a lot has been going on behind the scenes.
Today @_d1voy shares his latest research: "It's Always DNS in Claude's Sandbox: From Data Exfiltration to a Bidirectional DNS Shell," live now on Zenity Labs.
took a deep dive into Claude's new Chrome extension or should I say Agentic browser?
It introduces some interesting features and risks we haven't really seen in Atlas or Comet.
Accomplish AI 研究团队称发现并向 Anthropic 报告了多个沙箱逃逸漏洞,并公开其中一个名为 SharedRoot 的漏洞。该漏洞可逃逸 Cowork VM 这一内核级隔离方案,使攻击者获得对用户电脑的未授权访问;用户即使确信 Cowork 只能访问某个已上传文件夹,其整台电脑的内容仍会暴露给利用该漏洞的攻击者。团队认为,随着 AI 辅助的内核漏洞挖掘走向工业化,沙箱在结构上始终落后一个 N-day,因此隔离不能依赖 guest Linux 内核本身是干净的。完整攻击链的技术细节见其博客文章。

Introducing SharedRoot vulnerability: we recently found and reported several sandbox escape vulnerabilities to @AnthropicAI, and today we want to share one of these.
I think most people don't understand the severity of the situation we are facing, with AI-assisted kernel bug-finding industrializing. Sandboxes are structurally one N-day behind, all the time, so containment can't lean on a guest Linux kernel being clean.
SharedRoot enables escaping the Cowork VM (a kernel-level isolated solution, which is considered much more secure than the sandbox that ships with codex or claude code), allowing an attacker to gain unauthorized access to the user’s computer.
Exploiting the SharedRoot vulnerability uncovered by the @Accomplish_ai research team, a user who is certain Cowork only has access to a specific uploaded folder on their computer - actually exposes their entire contents of their computer to an attacker leveraging the Cowork vulnerability.
