Abstract--We present MH-1M, one of the most comprehensive and up-to-date datasets for advanced Android malware research. The dataset comprises 1,340,515 applications, encompassing a wide range of features and extensive metadata. T o ensure accurate malware classification, we employ the VirusT otal API, integrating multiple detection engines for comprehensive and reliable assessment. Our GitHub, Figshare, and Harvard Dataverse repositories provide open access to the processed dataset and its extensive supplementary metadata, totaling more than 400 GB of data and including the outputs of the feature extraction pipeline as well as the corresponding VirusT otal reports. Our findings underscore the MH-1M dataset's invaluable role in understanding the evolving landscape of malware. The pervasive spread of Android malware poses a significant challenge for cybersecurity research. This challenge stems mainly from the open-source nature and affordability of Android platforms, which grant users access to a large market of free applications. At the same time, malware continually evolves, adapting its tactics to execute more sophisticated and frequent attacks. Such attacks often result in data destruction, information theft, and several other cybercrimes [1], [2], [3]. Machine learning (ML) algorithms have been widely used to uncover malware and have demonstrated remarkable effectiveness in detection systems, leveraging their discriminative capabilities to identify new variants of malicious applications [4], [5], [6]. To mitigate these risks, researchers have developed a variety of methods for detecting Android malware, establishing machine learning as a central focus of contemporary mobile security research [7], [8], [9]. However, the effectiveness of ML models is highly dependent on the quality of the datasets used for training. Many existing datasets suffer from limitations such as outdated data, inadequate representation, and a limited number of samples and features, making them unsuitable for modern malware detection [10], [2], [11], [12]. These issues raise concerns about the reliability of reported performance metrics and can potentially lead to misleading conclusions [2]. A growing body of research in Android malware detection strongly supports the notion that increasing the number of discriminative features can significantly improve classification performance [13], [14], [15]. We present in Table I an overview of widely used Android malware datasets from recent years.

The increasing deployment of Large Language Model (LLM) agents for complex software engineering tasks has created a need to understand their problem-solving behaviours beyond simple success metrics. While these agents demonstrate impressive capabilities in automated issue resolution, their decision-making processes remain largely opaque. This paper presents an empirical study of agent trajectories, namely the execution traces capturing the steps agents take when attempting to resolve software issues. We analyse trajectories from three state-of-the-art code agents (OpenHands, SWE-agent, and Prometheus) on the SWE-Bench benchmark, examining both successful and failed attempts. Our investigation reveals several key insights into agent behaviour. First, we identify how distinct problem-solving strategies, such as defensive programming and context gathering, enable success in different scenarios. Second, we find that failed trajectories are consistently longer and exhibit higher variance than successful ones, with failure patterns differing significantly between agents. Third, our fault localisation analysis shows that while most trajectories correctly identify problematic files (72-81\% even in failures), success depends more on achieving approximate rather than exact code modifications. These and other findings unveiled by our study, provide a foundation for understanding agent behaviour through trajectory analysis, contributing to the development of more robust and interpretable autonomous software engineering systems.

High-quality data scarcity hinders malware detection, limiting ML performance. We introduce MalDataGen, an open-source modular framework for generating high-fidelity synthetic tabular data using modular deep learning models (e.g., WGAN-GP, VQ-V AE). Evaluated via dual validation (TR-TS/TS-TR), seven classifiers, and utility metrics, MalDataGen outperforms benchmarks like SDV while preserving data utility. Its flexible design enables seamless integration into detection pipelines, offering a practical solution for cybersecurity applications. I. Introduction Modern machine learning algorithms, particularly deep learning architectures, depend on large-scale datasets with reliable annotations to achieve optimal performance.

The rapid proliferation of Large Language Models (LLMs) has raised significant concerns about their security against adversarial attacks. In this work, we propose a novel approach to crafting universal jailbreaks and data extraction attacks by exploiting latent space discontinuities, an architectural vulnerability related to the sparsity of training data. Initial results indicate that when these discontinuities are exploited, they can consistently and profoundly compromise model behavior, even in the presence of layered defenses. The findings suggest that this strategy has substantial potential as a systemic attack vector. Disclaimer: This paper contains examples of harmful and offensive language.

Large Language Models (LLMs) are enabling novel applications of Artificial Intelligence (AI) and transforming human activities through conversational models (e.g., ChatGPT, DeepSeek, Gemini, Llama, and Claude). LLMs allow for natural human-AI interaction and specialized applications across multiple domains, including image generation (e.g., Adobe Firefly and Pixlr), code automation (e.g., GitHub Copilot and Amazon CodeWhisperer), and retrieval-augmented generation systems (e.g., Perplexity AI and IBM watsonx). The interactions may happen using different interfaces, such as via direct interaction with the user using a Web interface or indirectly via APIs.

OpenAI has signed a new deal valued at $38bn with Amazon that will allow the artificial intelligence giant to run AI workloads across Amazon Web Services (AWS) cloud infrastructure. The seven-year deal announced on Monday is the first big AI push for the e-commerce giant after a restructuring last week. Experts say this does not mean that it will allow OpenAI to train its model on websites hosted by AWS - which includes the websites of The New York Times, Reddit and United Airlines. "Running OpenAI training inside AWS doesn't change their ability to scrape content from AWS-hosted websites [which they could already do for anything publicly readable]. This is strictly speaking about the economics of rent vs buy for GPU [graphics processing unit] capacity," Joshua McKenty, CEO of the AI detection company PolyguardAI, told Al Jazeera. The deal is also a major vote of confidence for the e-commerce giant's cloud unit, AWS, which some investors feared had fallen behind rivals Microsoft and Google in the artificial intelligence (AI) race.

OpenAI has signed a $38bn (£29bn) contract with Amazon to access its cloud computing infrastructure, as the start-up continues its run of major partnerships to secure computing power . In 2025, the ChatGPT maker has signed deals worth more than $1tn with Oracle, Broadcom, AMD and chip-making giant Nvidia. Its latest deal reduces its reliance on Microsoft. As part of the seven-year agreement, OpenAI will gain access to Nvidia graphics processors to train its artificial intelligence models. The deal follows a sweeping restructure of OpenAI last week which saw it convert away from being a non-profit and changed its relationship with Microsoft to give OpenAI more operational and financial freedom.

Warnings of disruption and protests have come from police as more than 700 officers prepare to mount an operation in Birmingham for Aston Villa's Uefa Europa League match against Maccabi Tel Aviv. Officers will be keeping the public safe and to tackle any crime and disorder on Thursday, West Midlands Police said, with police horses, dogs, the force's drone unit, and road policing officers out in the city. Planned protests include one by supporters of Palestine, who want the match to be called off. Last month, a decision to ban Tel Aviv fans from the event became the focus of parliamentary-level debate . The Israeli club later said supporters would not travel to Birmingham for safety reasons.
