🧠 Metacognitive Myopia in Large Language Models (http://arxiv.org/pdf/2408.05568v1.pdf)

  • Large Language Models (LLMs) exhibit biases and stereotypes in moral judgments and evaluations due to biases in annotator selection, data approaches, and learning algorithms, highlighting the need for effective debiasing strategies.
  • LLMs lack metacognitive abilities, leading to biased outcomes caused by neglect of base rates, inappropriate statistical inferences, and reliance on invalid tokens and embeddings, which are especially problematic in high-stakes decisions.
  • Introducing metacognition to LLMs presents an opportunity for engineers and scientists to develop remedies for these biases, raising ethical concerns and emphasizing the importance of addressing these challenges in the implementation of LLMs.

πŸͺ² Learning-based Models for Vulnerability Detection: An Extensive Study (http://arxiv.org/pdf/2408.07526v1.pdf)

  • Sequence-based models demonstrated superior performance in detecting software vulnerabilities over graph-based models, showcasing their effective handling of source code structure.
  • The inherent instability of models to minor, semantically-preserving transformations in source code highlights a substantial challenge in achieving robust vulnerability detection.
  • Large Language Models (LLMs) like ChatGPT, while cost-effective, exhibited limited abilities in vulnerability detection, emphasizing the need for specialized models for this purpose.

πŸ“˜ Natural Language Outlines for Code: Literate Programming in the LLM Era (http://arxiv.org/pdf/2408.04820v1.pdf)

  • Large Language Models (LLMs) like Gemini and GPT-4 can generate high-quality natural language (NL) outlines for code, improving developer efficiency by aiding in code comprehension, maintenance, and navigation.
  • 60% of the outlines generated by LLMs were rated as excellent by developers, and 90% were considered acceptable or better, highlighting the potential of NL outlines to enhance software development practices.
  • NL outlines can accelerate the understanding and maintenance of code by providing bidirectional synchronization with code changes, thus reducing the time developers spend on program comprehension.

πŸ“› AttackER: Towards Enhancing Cyber-Attack Attribution with a Named Entity Recognition Dataset (http://arxiv.org/pdf/2408.05149v1.pdf)

  • The AttackER dataset, developed as the first cyber-attack attribution dataset tailored for Named Entity Recognition (NER), includes detailed annotations of 2640 sentences and 18 entity types to facilitate machine learning model training for automated cyber-threat analysis.
  • Experiments with Large Language Models (LLMs) like GPT-3.5, Llama-2, and Mistral-7B on the AttackER dataset demonstrate a significant enhancement in NER tasks, illustrating the dataset's effectiveness in improving AI-driven cyber-attack attribution.
  • Fine-tuning LLMs on the AttackER dataset led to improved performance in identifying cyber-attack entities, with GPT-3.5 showing robust F-1 scores, indicating the potential of custom-tailored datasets in enhancing NER applications within cybersecurity.

πŸ“Š Using Retriever Augmented Large Language Models for Attack Graph Generation (http://arxiv.org/pdf/2408.05855v1.pdf)

  • Large language models (LLMs), specifically GPT-4, have demonstrated a sophisticated ability to automate the generation of attack graphs and threat reports by leveraging information from the Common Vulnerabilities and Exposures (CVE) database.
  • The study highlighted the efficiency and accuracy of LLMs in processing unstructured textual data from threat reports and structured CVE information to generate comprehensive attack graphs, showcasing potential security vulnerabilities and attack paths.
  • Automated attack graph generation via LLMs offers significant advancements in cyber threat analysis, providing nuanced understanding of vulnerabilities and attack vectors with real-time relevance, thereby enhancing the security posture with reduced manual effort.

🫣 Multimodal Large Language Models for Phishing Webpage Detection and Identification (http://arxiv.org/pdf/2408.05941v1.pdf)

  • Large Language Models (LLMs) have shown significant potential in detecting phishing webpages through multimodal data analysis, achieving high detection rates and precision with the ability to provide interpretable evidence for their decisions.
  • Domain verification as a second phase in phishing detection using LLMs substantially increases detection accuracy, with experiments showing a detection rate increase from 65% to 92% and precision up by 10%.
  • Adversarial attacks involving perturbed logos and webpage sources were found to be less effective against LLMs due to their robustness stemming from training on massive, diverse datasets.
