Researchers show jailbreaks embedded in SKILL.md Markdown files can propagate through agent frameworks and induce prohibited behavior.
arXiv cs.CR (Cryptography & Security)jailbreakprompt-injectionagentsFeed excerpt
arXiv:2610.37738v1 Announce Type: new Abstract: Modern agent frameworks allow users to provide Markdown files containing system prompts, tool descriptions, and skill definitions (e.g., SKILL.md), which are incorporated into the agent's context during initialization. In this work, we investigate whether this configuration mechanism can also serve as an injection channel: can a jailbreak embedded in a Markdown skill file propagate through an agent and induce prohibited behavior? To answer this question, we construct a LangChain-based question-answering agent whose system prompt is assembled from a user-provided Markdown file. We embed a jailbreak combining persona manipulation with a GPTFUZZER-based attack and evaluate its effectiveness across seven contemporary open-weight models using 270 forbidden questions spanning nine harm categories. Under a benign system prompt, the models exhibit near-complete refusal behavior, with a mean attack success rate (ASR) of just 0.5%. In contrast, the injected skill file raises the mean ASR to 45%, reaching 68.9% for individual models. We further evaluate two payload obfuscation strategies: an invisible zero-width character-based stealth payload a…
Pretraining data poisoning at 0.1% can plant a remote code execution backdoor in CLI agents built on Qwen3 models.
arXiv cs.CR (Cryptography & Security)data-poisoningbackdoorllmrceFeed excerpt
arXiv:2610.37741v1 Announce Type: new Abstract: Large language models are pretrained on vast, uncurated corpora scraped from the public web. This creates a security risk from attackers who plant poisoned content in the pretraining data. We show for the first time that such poisoning can plant a remote code execution backdoor in an agent, causing it to execute attacker-chosen commands on the user's machine. To measure the threat end to end, we pretrain Qwen3 models from scratch at sizes 0.6B, 1.7B, and 4B, and then post-train each into a CLI agent using a clean pipeline. Poisoning only 0.1% of the pretraining corpus with our new poison design implants the backdoor: the deployed agent executes the malicious command when the trigger is present while behaving normally on clean inputs. The attack success rate (ASR) increases with model scale, with the 4B model reaching roughly 92% ASR at a 0.1% poison rate and staying positive even when the poisoning rate drops to 0.0005%. Our code is available at https://github.com/safety-research/agentic-backdoor.
SparseBleed is a hardware-level attack exploiting accelerator sparsity optimizations to steal training attributes and bypass privacy defenses.
arXiv cs.CR (Cryptography & Security)side-channelprivacyhardwareFeed excerpt
arXiv:2610.38110v1 Announce Type: new Abstract: Deep neural networks (DNNs) are widely deployed in safety- and privacy-critical domains such as healthcare and finance, where models are trained on confidential data. This paper presents the first hardware-level attribute-stealing attack that bypasses state-of-the-art privacy defenses, revealing that accelerator optimizations intended for performance can directly undermine data confidentiality. SparseBleed requires no access to gradients, logits, model weights, ground-truth labels, power traces, DVFS manipulation, shared caches, or other channels. Instead, we show that sparsity-driven execution paths encode stable timing signatures that act as a surrogate for model confidence, enabling high-fidelity attribute inference from a single query. SparseBleed generalizes across heterogeneous backends and hardware engines, including Intel AVX2/AVX-512/AMX, NVIDIA Ampere Tensor Cores with 2:4 sparsity, and nine well-known sparse and dense libraries such as Intel oneDNN, oneMKL SparseBLAS, and NVIDIA cuSPARSE. We evaluate SparseBleed to infer sensitive input attributes and true output labels. On Texas-100X, SparseBleed infers sensitive input att…

Encore compiles public proof-of-concept exploits into CVE-specific threat hunting rules, covering 45 evaluated CVEs.
arXiv cs.CR (Cryptography & Security)threat-huntingcvedetectionFeed excerpt
arXiv:2610.37872v1 Announce Type: new Abstract: Public exploit code for a newly disclosed vulnerability usually appears before any published rule that detects its exploitation. Of the 45 CVEs we evaluate, 37 ever received a Sigma, Elastic or Splunk rule; in 33 the exploit came first, by a median of 22 days. Analysts still write every rule by hand. We present Encore, which compiles a public Python proof-of-concept exploit (PoC) into CVE-specific hunting rules over a web service's existing logs, without running it. Encore rests on the PoC Behavior Alignment Principle: a PoC performs the exploit, so its code already provides a rule's HTTP requests, payloads and host operations. That is hard to act on: a PoC is written against libraries and runs on the attacker's machine, while the target's web-server, proxy and host logs record only what arrived and what it did. Encore closes the gap with a map from library calls to the operations they cause, built once per library, keeping only the operations visible on the target. For 12 of the 45, Encore's rule states the exploit's own payload fragment or host operation, which is evidence of the exploit itself, and not of traffic to its endpoint. O…
Six-module scanner detects local and composite vulnerabilities across agent skills in public repositories.
arXiv cs.CR (Cryptography & Security)agentsscannervulnerabilityFeed excerpt
arXiv:2610.37901v1 Announce Type: new Abstract: An agent skill packages natural-language instructions, scripts, and reference files that an LLM-based agent loads for a task. Skills may access the file system, shell, and network under user-authorized permissions; weaknesses can lead to unsafe execution. Existing scanners primarily target malicious skills, not unintended vulnerabilities in public repositories, and analyze skills in isolation, overlooking multi-skill interactions. To address these gaps, we developed a six-module scanner: Content Extraction, Local Analysis, Composite Analysis, Validation, Reporting, and Mitigation. Local Analysis detects unintended vulnerabilities in benign skills. On a 556-case leaderboard subset of SkillTrustBench, it achieved 95.90% recall with a 4.22% false positive rate; on a balanced sample of 1,000 MalSkillBench skills, its F1 was 0.947, outperforming Cisco's Skill Scanner, NVIDIA's SkillSpector, AgentSkillsScanner, and SkillSieve.

Proposes Role Grounding Attack exploiting agent memory systems to misattribute attacker-supplied preferences to victim users via social interactions.
arXiv cs.CR (Cryptography & Security)llm-agentsprompt-injectionmemoryFeed excerpt
arXiv:2610.38209v1 Announce Type: new Abstract: LLM-based agents now share experiences on social platforms and remember new preferences to enhance their performance. However, existing memory systems contain a vulnerability in role-to-principal attribution that attackers can exploit. We identify Role Grounding Misattribution, in which an attacker-designed interaction causes the victim agent to incorrectly record a preference from the attacker as a preference of the victim's user. Specifically, we are the first to formalize Role Grounding Attack (RGA), an attack model that exploits this vulnerability through nested conversation structures. In the memory formation stage, an experience-sharing post quoting a conversation between the attacker agent and its user is published, which explicitly identifies its publisher. The inner conversation expresses preferences from the user of the attacker agent. When the victim agent remembers preferences from this nested structure, its memory loses the context binding and grounds the attacker's preference to the victim's user instead. In the memory retrieval stage, the misattributed preference persists and influences the victim agent's decisions when…
WebMaze presents deception techniques that divert LLM-powered web vulnerability scanners while preserving genuine application functionality.
arXiv cs.CR (Cryptography & Security)web-securityllm-scannersdeceptionFeed excerpt
arXiv:2610.38524v1 Announce Type: new Abstract: Large language models (LLMs) have enabled more effective vulnerability scanning of web applications. However, these capabilities also make it significantly easier for attackers to automate cyberattacks on the web. In this work, we investigate how to divert malicious LLM-based web scanning, with preservation of genuine functionality as a deployment requirement. We systematically study six LLM-based scanners and summarize how they gather information and iteratively select actions based on observations. Guided by the study, we then present WebMaze, a defense that preserves genuine application functionality while diverting LLM-based scanners to a generated decoy world. WebMaze embeds functionality-coupled traps in genuine pages and constructs view-tailored interactive decoy worlds from the application's existing views. The traps blend into genuine components and expose entry points to decoy worlds that sustain exploration through connected pages and interactions without changing genuine functionality. Across 12 web applications and three LLM-based scanners under the default no-disclosure setting, decoy pages account for an average of 93.0…

arXiv:2610.38617v1 Announce Type: new Abstract: We ask what AI coding agents and AI security harnesses find that deterministic static application security testing (SAST) does not, and what they miss that SAST catches. VulnBench 2.0 is a benchmark of 108 hand-curated, attacker-reachable vulnerabilities in 20 open-source web applications in Go, JavaScript/TypeScript, Python and Java; 62 flow across more than one file.

Paper describes an attack where a malicious peer component manipulates runtime feedback to hijack another developer's coding agent.
arXiv cs.CR (Cryptography & Security)prompt-injectioncoding-agentsresearchFeed excerpt
arXiv:2610.38799v1 Announce Type: new Abstract: Coding agents increasingly develop, test, and integrate software whose components are owned by different developers, teams, or services. This exposes a distinct attack surface: a malicious or compromised peer development role can manipulate a live component of the software under development (e.g., a backend service, test harness, CI job, or deployment service) and influence the runtime feedback that another role's coding agent must process to complete its task. Although such a component has legitimate diagnostic authority to report its own state, it has no action authority over the victim's local files, credentials, shell, or development environment. We introduce Cross-Boundary Adversarial Runtime Injection (CARI), a direct runtime-feedback injection setting that exploits this authority mismatch. Rather than explicitly compromising the victim's prompt, model, tools, or local environment, the attacker covertly embeds malicious instructions in task-relevant runtime feedback produced by a peer-controlled development component. The victim then interprets that feedback as part of normal debugging or recovery, and may translate the diagnost…
Study finds self-evolving personal LLM agents become more vulnerable to indirect prompt injection after learning from user feedback.
arXiv cs.CR (Cryptography & Security)prompt-injectionllm-agentsresearchFeed excerpt
arXiv:2610.39122v1 Announce Type: new Abstract: Self-evolving personal agents act for users and learn from user feedback. However, if an agent obeys an instruction that an untrusted third party hides in content, the third party gains control of the agent. Such indirect prompt injection (IPI) poses severe risks. We investigate whether self-evolution degrades the robustness of personal agents to IPI. To study this question, we design a controlled two-phase methodology. In the adaptation phase, the user asks the agent to read external content and complete the task described in it, a common request in daily use. The agent then learns from the user's feedback and improves itself as designed. In the test phase, a third party writes a similar task into new external content, but the user's test request does not authorize the injected task. Using this methodology, we build multiple tasks with diverse test instances in different domains for a real personal agent. Our extensive experiments reveal that self-evolution substantially degrades robustness to IPI. Specifically, compared with the base agent, which does not evolve from user feedback, the average attack success rate rises by 14.0--48.8…
Audit finds widespread near-duplicate images and test-train leakage in ten malware-as-image benchmarks, inflating reported classifier accuracy.
arXiv cs.CR (Cryptography & Security)malwarebenchmarksresearchFeed excerpt
arXiv:2610.39351v1 Announce Type: new Abstract: Classifying malware binaries rendered as images is a popular approach to malware family identification, and papers on the standard benchmarks for this task report accuracies of 97-99%. In this paper we audit ten of these benchmarks for near-duplicate images and test-train leakage, and retrain standard classifiers under naive and content-aware splits. Deduplicating by file hash, which is the standard practice, does not prevent leakage, because distinct binaries render to identical images. Deduplicating on image content reduces top-1 accuracy by up to 8 points and macro-F1 by up to 15 points on the released benchmarks we find leaky. The rendering step also adds duplication, since byteplots of the same binaries contain 19.7% near-duplicates where static feature vectors contain 2.2%, and changing the width at which bytes are wrapped into rows reduces accuracy by 20 to 33 points, although no byte changes. We recommend that content-level duplication and a non-image baseline be reported alongside accuracy.
Systematic evaluation tests five jailbreak attack families and four defenses across seven open and API LLMs including Llama-3 and Qwen2.5.
arXiv cs.CR (Cryptography & Security)jailbreakllmresearchFeed excerpt
arXiv:2610.39509v1 Announce Type: new Abstract: Large language models (LLMs) deployed in safety-critical settings must resist adversarial inputs designed to elicit harmful outputs. We present a systematic empirical evaluation of five adversarial jailbreaking attack families---direct requests, roleplay-based jailbreaking, hypothetical framing, instruction override, and obfuscation---across seven open-weight and API-accessible LLMs: Llama-3-8B, Llama-3.1-8B, Llama-3.2-3B, Mistral-7B, Qwen2.5-7B, Gemma2-9B, and Phi-4-14B. We further evaluate four defense mechanisms: keyword blacklisting, self-reminder prompting, paraphrase-based sanitization, and perplexity-based filtering against the two most vulnerable models. Our results reveal that obfuscation attacks achieve a mean attack success rate (ASR) of 54.3% across all models and constitute the most transferable adversarial vector, bypassing every evaluated model with nonzero success. We find that model size does not predict adversarial robustness (Spearman r=-0.57, p=0.18), and that models within the same architecture family exhibit dramatically different vulnerability profiles. Self-reminder prompting achieves the most consistent defens…
SEAL proposes a learned soft-prompt sanitizer that filters indirect prompt injections from tool outputs for local LLM agents.
arXiv cs.CR (Cryptography & Security)prompt-injectionllmdefenseFeed excerpt
arXiv:2610.39758v1 Announce Type: new Abstract: Indirect prompt injection threatens local LLM agents through untrusted tool outputs, motivating defenses that suppress attacks while preserving task evidence under limited inference budgets. We introduce SEAL, which learns a soft prompt and scoring readout offline to sanitize tool outputs using a frozen task model. SEAL constructs scoring queries from trusted initial context and the learned prompt, keeping the reference independent of inspected tool text. It scores tokens without normalization across context tokens and uses preservation regularization to encourage retention of useful evidence during localized deletion. This design requires neither defense-generated tokens nor a separate verifier model. Across AgentDojo and AgentDyn, SEAL suppresses attacks while improving task completion under attack. Specifically, on AgentDojo, SEAL reduces attack success from 34.6\% to 0.1\% and increases Joint---task completion without attack success---from 51.4\% to 77.5\%, while using approximately $127\times$ fewer defense-related tokens than PISanitizer, a state-of-the-art prompt injection defense. Replication on a second backbone with the same…
A fault attack on deterministic CSIDH repeatedly faults a fixed secret-dependent step to recover keys.
arXiv cs.CR (Cryptography & Security)csidhfault-attackpost-quantumFeed excerpt
arXiv:2610.39910v1 Announce Type: new Abstract: Deterministic variants of CSIDH remove randomness from the group action, either through implementation techniques or, as in Houben's deterministic CSIDH and OSIDH-LD, by design. Since earlier fault attacks on CSIDH mostly target random point sampling, determinism seems to close that avenue. We show that it opens another: every secret-dependent step occurs at a fixed, public point of every execution, so an attacker can fault the same step repeatedly. Our attack forces the mask that selects which of two lanes computes the next isogeny to zero, for example by skipping one instruction. Whether the output changes reveals whether a secret exponent reaches a chosen threshold, and a binary search over these thresholds recovers the full key with one fault per execution: at most 297 oracle queries for OSIDH-LD and 222 for deterministic CSIDH with CSIDH-512-sized keys. We recover full OSIDH-LD keys in a software fault simulation of the reference implementation, and show on a ChipWhisperer-Lite that the targeted instruction is skipped with probability at least 0.94 at an isolated fault position. Finally, we argue that fault resistance requires gi…

arXiv:2610.40396v1 Announce Type: new Abstract: Despite growing capabilities, LLMs remain susceptible to prompt injections: malicious inputs that can manipulate or hijack models. In particular, it has recently been observed that LLMs can exhibit role confusion (Ye et al., 2026), where models attribute the source of text based on its style instead of its labeled role. Malicious text in tool outputs (for instance, a malicious webpage accessed by an agent) can leverage role confusion to impersonate the user, an attack we call role spoofing}. In this work, we seek to understand and mitigate role spoofing. We study how models track "who said what" in a conversation, showing that they use cues from both content (e.g., semantics and writing style) and structure (e.g., control tokens and formatting). We show that LLMs are highly susceptible to role spoofing attacks that combine both fake structure and content. Additionally, in a toy setting, we show that adversarial training which teaches the model to ignore content-based injections does mitigate content-based attacks but leaves the model susceptible to structure-based attacks. This can explain why frontier models, with increased resistanc…
