- Advanced persistent threats campaigns and attributionPublication . Brandão, Pedro; São Mamede, Henrique; Correia, MiguelThe main objective of this study is to carry out a systematic review of the literature regarding Advanced Persistent Threats (A.P.T.) and A.P.T. Campaigns. The work is focused on campaigns with geographical origin in China and for this reason, the main A.P.T. campaigns from that region are analyzed. All types of documentation were used for the systematic literature review, including gray literature, such as reports from official and government agencies. The Attribution is one of the most important parts of the APT problem, this study tries to demonstrate that it was possible to make the Attribution in relation to certain Groups in China, groups that attacked many western countries via APT. The problem to be solved is to Assign these Groups, that is, to know who are the authors of the APT. The scope of work is specifically the APT attacks and their possible origin in China.
- A domain-agnostic virtual choreography framework for digital twins: an oil spill applicationPublication . Cassola, Fernando; Cavaleiro, Vitor; Lacet, Demetrius; Correia, Miguel; Oliveira, Marco Amaro; Carvalho, Alexandre Valle de; Morgado, LeonelDigital Twins (DTs) for the ocean are rapidly emerging as essential tools for understanding, forecasting, and managing environmental phenomena. However, most existing DT visualization solutions are tightly coupled to specific platforms and lack semantic coherence and interoperability—challenges that are particularly critical in federated and distributed DT systems. Furthermore, visualizing dynamic and spatio-temporal behaviors, such as oil spills, across multiple rendering environments remains a complex, platform-dependent task. In this paper, we present VChor, a domain-agnostic virtual choreography framework designed to address these limitations. Our approach integrates model-driven engineering, semantic web technologies, and platform-independent representations to support the declarative specification of behaviors and visual mappings. A single VChor instance describes spatio-temporal dynamics and associated actions, and can be interpreted by multiple visualization engines (e.g., Unity3D and CesiumJS) without the need for code recompilation or platform-specific programming. We demonstrate our approach through a real-world oil spill monitoring use case, developed in the context of the ILIAD H2020 project, and encapsulated within a modular Application Package. This package automates the generation, validation, and transformation of virtual choreographies from raw data to platform-specific outputs. The framework promotes interoperability, reusability, and scalability, while supporting FAIR principles in environmental Digital Twin workflows. The findings highlight VChor’s potential to streamline scenario modeling, enable cross-platform visualization, and support decision-makers with accurate, flexible, and reusable visual representations of ocean dynamics.
