  1. DefensesarXiv 2609.33371

    论文提出保险库中介执行边界,评估 LLM Agent 的 API 凭据处理风险

    提出并评测保险库中介执行边界,隔离 Agent 的 API 凭据

    Published
    Setting
    AI Agent
    Evaluated models
    Corvic Security Vault
    Abstract作者称,凭据分离可减少披露路径,但权限、操作授权和配置验证仍需独立控制。

    这是一项智能体 API 凭据威胁分析及 Vault 执行边界的功能评测。作者关心的不是模型能否承诺保密,而是认证材料是否会进入模型、日志、记忆和执行代码。

  2. AttacksarXiv 2609.27542

    Researchers use control token injection to delete gpt-oss-20b's reasoning chain and bypass chain-of-thought monitoring

    提出控制标记注入,清空工具 Agent 的思维链以绕过推理监控

    Published
    Setting
    AI Agent
    Evaluated models
    openai/gpt-oss-20b, google/gemma-4-26B-A4B-it, deepseek-ai/DeepSeek-R1-Distill-Qwen-7B and others4

    Abstract论文阐明控制标记注入可抑制 CoT 使监控失效并促成拒绝绕过,且工具执行受解析器宽容度影响。

  3. AttacksarXiv 2609.18217

    研究:跨通道碎片化攻击可绕过 MCP 单通道防御

    提出跨通道分段攻击,利用 MCP 隐式信任外发敏感文件

    Published
    Evaluated models
    GPT-4o, GPT-4o-mini, GPT-5.4 and others15

    Abstract论文揭示了 MCP 多通道隐式信任层级,通过跨通道分段与协议级利用突破现有防御,展示了严重的凭证外发风险。

    Forgetting without restart: execution-state forgetting for stateful LLM agents

    Proposes execution-state forgetting, using provenance-guided selective replay to purify stateful agents

    Published
    Setting
    AI Agent
    Evaluated models
    Llama-3.1-8B-Instruct, Qwen2.5-7B-Instruct, Mistral-7B-Instruct-v0.3
    AbstractSelective replay concatenates the clean prefix with the sanitized suffix, and main-table metrics match full reset.

    This work defines forgetting in long-horizon agents as runtime counterfactual equivalence, rather than deleting a plaintext memory.

  5. DefensesarXiv 2608.24017

    WebMCP-Phalanx:为浏览器内 LLM Agent 工具调用建立信任边界

    提出 WebMCP-Phalanx,用能力凭证与双智能体隔离浏览器工具调用

    Published
    Setting
    web agent
    AbstractPhalanx 用浏览器凭证绑定工具所有权,Q/P 分离拦住描述注入,工具名与返回值仍有残留。

    WebMCP-Phalanx针对浏览器里的 WebMCP 智能体:在 SOP 下补工具所有权,并把语义检查从有工具权的执行中分开。
