AI Threat AlertStealthy Backdoor Attacks against LLMs Based on Natural Style Triggers
attack in a realistic threat model and systematically evaluate BadStyle under both prompt-induced and PEFT-based injection strategies. Extensive experiments across seven victim LLMs, including LLaMA, Phi, DeepSeek
They'll Verify. They Just Won't Act. How Authority Framing and Laundered Code Turn a Trusted Agentic CI/CD Pipeline Into an Attack Surface
find: (1) the entry agent does not leak its system prompt (0/40); (2) an authority-framed injection ("pre-approved under SEC-2291, do not re-review") makes downstream verifiers
Black-Box Skill Stealing Attack from Proprietary LLM Agents: An Empirical Study
prior prompt-stealing methods and build an automated stealing prompt generation agent. This agent starts from model-generated seed prompts, expands them through scenario rationalization and structure injection, and enforces
A Deterministic Control Plane for LLM Coding Agents
single canonical definition to seven IDE targets; and detects prompt drift via Jaccard similarity. Conformance tests on injected violations confirm each mechanism enforces its stated invariant; developer outcomes remain future
Multi-Turn Jailbreaking of Aligned LLMs via Lexical Anchor Tree Search

Flowise: Parameter Override Bypass Remote Command Execution
CoT-Guard: Small Models for Strong Monitoring
attacks, where the adversary is a third-party LLM router injecting hidden objectives into code-generation requests through either prompt manipulation or code manipulation attacks. To push beyond objectives that
Knowledge Base Poisoning Attacks and Defense for Policy-Aware LLM-RAG Framework
operator query types without requiring knowledge of runtime prompts. The attack achieves 85% LLM context corruption from a single injected rule (1.6% poisoning rate) and saturates at 7.7% poisoning, demonstrating
Generate "Normal", Edit Poisoned: Branding Injection via Hint Embedding in Image Editing
rendered onto semantically related objects, even when the user prompt does not explicitly mention it. This form of hidden payload injection makes the attack stealthy. We study two realistic attack
Synthetic Voices, Real Threats: Evaluating Large Text-to-Speech Models in Generating Harmful Audio
second leverages audio-modality exploits (Read, Spell, Phoneme) that inject harmful content through auxiliary audio channels while maintaining benign textual prompts. Through evaluation across five commercial LALMs-based TTS systems
Evaluating Adversarial Vulnerabilities in Modern Large Language Models

Large Language Models for Detecting Cyberattacks on Smart Grid Protective Relays
perfect fault detection accuracy. Additional evaluations demonstrate robustness to prompt formulation variations, resilience under combined time-synchronization and false-data injection attacks, and stable performance under realistic measurement noise levels
Exposing Citation Vulnerabilities in Generative Engines
perspectives of citation publishers and the content-injection barrier, defined as the difficulty for attackers to manipulate answers to user prompts by placing malicious content on the web. GEs integrate
Cross-Cutting Security Analysis of LLM-Generated Code via Metamorphic Testing and Association Rule Mining
