Security & Safety
1. QuickFox Supply Chain Attack Delivers FDMTP Backdoor via Trojanized Windows Installer
Cybersecurity researchers have disclosed what has been described as a "long-standing supply chain attack" on QuickFox, a virtual private network (VPN) and network acceleration tool designed for overseas Chinese users.
According to Fortinet FortiGuard Labs, the supply chain attack has been ongoin...

2. Adversarial Attacks in Multi-Agent LLM Pipelines: Unveiling Structural Vulnerabilities in Agentic AI Architectures
arXiv:2608.00718v1 Announce Type: cross Abstract: Multi-agent LLM pipelines orchestrate multiple specialized language model agents into structured workflows where intermediate outputs are passed across agents to solve complex tasks. This design introduces a security gap absent in single-agent se...

3. SIEVE: Selective Integrity Verification and Escalation for Defending LLM Agents against Indirect Prompt Injection
arXiv:2512.06716v3 Announce Type: replace Abstract: Large Language Models (LLMs) are increasingly used as the core of agentic systems due to their strong reasoning, planning, and tool-use capabilities. By interacting with external environments, LLM agents can execute real-world tasks on behalf o...

4. QShield: Securing Neural Networks Against Adversarial Attacks using Quantum Circuits
arXiv:2604.10933v2 Announce Type: replace-cross Abstract: Deep neural networks remain highly vulnerable to adversarial perturbations, limiting their reliability in security- and safety-critical applications. To address this challenge, we introduce QShield, a modular hybrid quantum-classical neur...

5. Evading Chain-of-Thought Monitoring Through Model Poisoning
arXiv:2608.02820v1 Announce Type: cross Abstract: Chain-of-thought (CoT) monitoring is an increasingly important component of AI safety stacks but relies on the assumption that a model's reasoning trace is informative about its actions. This work studies the limits of CoT monitoring through the ...

6. When Prompts Control Robots: Prompt Injection Attacks in Multi-Agent Robotic Systems
arXiv:2608.00747v2 Announce Type: cross Abstract: Large language models are increasingly integrated into autonomous robotic systems for task planning and control, but this integration exposes them to prompt injection attacks that can lead to unsafe decisions and physical harm. Multi-agent settin...

7. CrackedPDFs: A Controlled Benchmark for Hidden Prompt Injection in PDFs
arXiv:2607.19396v2 Announce Type: replace Abstract: Document-based LLM systems often flatten a PDF before guardrails inspect it. That step can discard evidence that an instruction was never visible to the user. We introduce CrackedPDFs, a controlled benchmark for hidden prompt injection in PDFs....

8. Omega-S: A Functional Resilience Index for LLM Fine-Tuning
arXiv:2608.03887v1 Announce Type: new Abstract: Fine-tuning a large language model on new data degrades what it previously learned. We present Omega-S, a drop-in penalty computed from the weight matrix alone: it needs no previous-task data, no Fisher matrix and no stored copy of the old weights....
