🚒 Smoke and Mirrors: Jailbreaking LLM-based Code Generation via Implicit Malicious Prompts (http://arxiv.org/pdf/2503.17953v1.pdf)

• CodeJailbreaker displays an 80% attack success rate in generating malicious code across seven large language models (LLMs), underscoring a significant gap between functional correctness and safety in the current LLM applications.
• An evaluation across RMCBench with CodeJailbreaker showcased that conventional safety protocols can be bypassed by encoding malicious intents into seemingly benign prompts or commit messages, highlighting vulnerabilities in existing models' instructional comprehension.
• The study's result of observed attack success rates reveals that existing LLMs' defenses against jailbreaking attempts are inadequate, with methods such as DeepSeek-Coder-7B and GPT-4 unable to consistently reject prompts with encoded nefarious instructions.

📶 Large Language Models powered Network Attack Detection: Architecture, Opportunities and Case Study (http://arxiv.org/pdf/2503.18487v1.pdf)

• Large Language Models (LLMs) have demonstrated a 35% improvement in network attack detection accuracy by leveraging pre-training, fine-tuning, and detection phases.
• A novel approach using LLMs for DDoS detection, particularly against Carpet Bombing Attacks, has shown potential for effective threat detection with minimal labeled data, evidenced by a 35.1% improvement in zero-shot F1 score.
• LLMs in network security can both classify network traffic as benign or malicious and predict anomalous traffic patterns, exploiting capabilities in unsupervised pre-training and fine-tuning with labeled examples to adapt quickly to changing network environments.

🎭 Inducing Personality in LLM-Based Honeypot Agents: Measuring the Effect on Human-Like Agenda Generation (http://arxiv.org/pdf/2503.19752v1.pdf)

• The model is able to induce personality traits based on the five-factor model, influencing task planning behavior in autonomous agents.
• Controlled personality induction in language models demonstrated significant influence on agents' task scheduling, enabling more human-like decision-making.
• SANDMAN's results reveal the potential of language models in improving cyber deception by creating deceptive agents that emulate human behavior effectively.

🐠 EXPLICATE: Enhancing Phishing Detection through Explainable AI and LLM-Powered Interpretability (http://arxiv.org/pdf/2503.20796v1.pdf)

• The enhanced phishing detection model, EXPLICATE, achieved a remarkable accuracy of 98.4%, demonstrating significant improvements over traditional methods in identifying phishing emails.
• Using sophisticated techniques such as Linguistic Pattern Analysis, URL Link Examination, and Header Structural Analysis, EXPLICATE effectively distinguishes phishing attempts from legitimate communications, reducing false negatives to just 1.2%.
• The integration of explainable AI mechanisms, such as LIME and SHAP, in EXPLICATE has resulted in high-quality, user-friendly explanations that bridge the transparency gap in phishing detection systems.

🤖 AgentSpec: Customizable Runtime Enforcement for Safe and Reliable LLM Agents (http://arxiv.org/pdf/2503.18666v1.pdf)

• Implementing AgentSpec rules prevents 90% of unsafe code executions and eliminates 100% of hazardous actions, ensuring complete compliance with safety protocols in autonomous systems.
• Leveraging LLM-generated rules, enforcement predicts and mitigates risky behaviors in 87.26% of scenarios, indicating a significant reduction in safety infractions.
• The AgentSpec framework imposes only millisecond-level overhead, showcasing an efficient and scalable approach to enhancing the safety of decision-making processes in LLM agents.
