  1. AttacksarXiv 2610.13928

    AI models can provably hide arbitrary capabilities

    Proposes digital lock compilation, encrypting executable networks into host weights to hide arbitrary capabilities

    Published
    Evaluated models
    Gemma 3 270M
    AbstractThe authors use a digital lock to hide an executable capability and state that elicitation on the chemistry and parity tasks did not recover the capability.

    The authors construct a class of backdoors that encrypt an executable network into the weights, used to discuss the limits of white-box elicitation audits under supply chain attacks.

  2. AttacksarXiv 2610.06049

    研究者提出仅修改 SAE 解码器的后门攻击,可在不改动语言模型的情况下植入行为

    提出只改 SAE 解码器的后门,在冻结语言模型上植入代码插入

    Published
    Evaluated models
    Gemma 3 4B Instruct, Qwen3 1.7B, Llama 3.1 8B Instruct
    Abstract只改解码器的 SAE 可带上代码插入后门,且若干常规质量指标变化不大。

    只改 SAE 解码器、冻结编码器与语言模型,即可把代码插入行为放进推理时的辅助组件。作者把这视为 SAE 供应链问题:checkpoint 一旦替换某一层激活,就参与后续计算,而不只是解释工具。

  3. AttacksarXiv 2609.36956

    The researchers propose Controlled Decoding Attacks, jailbreaking black-box LLMs through a text-only interface

    提出 BLINDBIAS,通过纯文本续写与前缀控制越狱黑盒模型

    Published
    Attacker
    Black-box
    Evaluated models
    GLM-5, Gemini-3.5-Flash, Qwen3-32B and others4
    Abstract作者认为,隐藏数值概率并不足以消除支持重复采样和前缀续写的解码攻击面。

    BLINDBIAS 是一种针对 sample-only 续写接口的 black-box 解码时越狱框架,研究没有目标数值概率时,采样能否支持逐步控制。

    Researchers steal proprietary LLM inference chains via cross-model compatibility of encrypted inference blocks

    利用加密思维块的跨模型重放,诱导弱模型逐字转写专有推理链

    Published
    Attacker
    Black-box
    Evaluated models
    Claude Opus 4.8, Claude Sonnet 4.6, Claude Haiku 4.5 and others13

    Abstract论文揭示了客户端加密思维块跨模型互换漏洞,提出了低成本提取方法并给出防御方案。

  5. 论文提出随机插入攻击,利用自回归一致性绕过 LLM 安全对齐

    解释自回归一致性如何导致浅层安全对齐,并提出随机插入攻击

    Published
    Abstract作者用自回归一致性串起浅层对齐、插入攻击和最坏延续对齐。

    作者把浅层安全对齐和一类续写攻击都归到自回归一致性上。

  6. The Continuation vs. Refusal Debate: Mechanism Analysis of Continuation-Triggered Jailbreaks in Large Language Models

    Analyzing the attention head mechanism of continuation-triggered jailbreaks and proposing HCS

    Published
    Evaluated models
    LLaMA-2-7B-Chat, Qwen2.5-7B-Instruct
    AbstractThe authors state that jailbreaks arise from competition between two types of heads, and that HCS plus distillation can use this competition for inference-time intervention.

    The authors use attention head mechanism analysis for continuation-triggered jailbreaks: under the same harmful instruction, moving the continuation suffix from after the instruction to outside the prompt boundary makes the model more likely to continue generating along the suffix.

    研究者提出面向多轮对话的视觉记忆注入攻击 VMI

    提出 VMI,用扰动图像在多轮对话中潜伏并仅在触发话题输出预定消息

    Published
    Evaluated models
    Qwen2.5-VL-7B-Instruct, Qwen3-VL-8B-Instruct, LLaVA-OneVision-1.5-8B-Instruct and others5
    AbstractVMI 让扰动图像在多轮 LVLM 中潜伏,作者称触发话题出现后仍可输出预定消息。

    VMI 是面向多轮 LVLM 的定向图像攻击:第三方发布带小扰动的图像,良性用户把它当作普通输入。

  8. AttacksarXiv 2602.08563

    Stateless yet not forgetful: implicit memory in LLMs as a hidden channel

    提出隐式记忆时间炸弹,使模型跨独立交互累积隐藏状态后激活

    Published
    Evaluated models
    GPT-4o, GPT-4.1, GPT-5.2 and others12
    Abstract作者展示时间炸弹可由提示词或微调诱导。

    作者把这篇工作定位为立场论文:再摄入存在时,按无状态设计的 LLM 仍可能经自身输出携带状态。要处理的问题是,这种不依赖外部记忆模块的通道会让风险跨过单次请求,而单触发测试看不到完整条件。
