AI-Enhanced Threat Intelligence Sharing against Online Harm and Crypto Crimes: Privacy-Preserving Analytics and Public-Private Coordinated Response and Recovery

Dr Asma Patel

Dr Bogdan Adamyk

Online harms and crypto-enabled crimes increasingly use crypto payments and dark-web services to scale abuse, including pay-in-crypto sextortion, ransomware monetisation, fraud-as-a-service marketplaces, and laundering and cash-out networks. The indicators and evidence needed to detect and mitigate these activities are fragmented across banks and payment service providers, crypto businesses, online platforms, cyber security providers, and law enforcement. Privacy, legal, and trust constraints limit the speed and quality of intelligence exchange, and sharing often happens only after escalation or harm has occurred. This undermines timely, coordinated response and recovery and prevents effective real-time collaboration.

This PhD will address that gap by developing an advanced, privacy-preserving intel-to-action framework that enables public and private organisations to share actionable intelligence and coordinate response and recovery without transferring raw sensitive data. It will apply AI-enhanced analytics using privacy-preserving collaboration centred on federated learning, with selective use of homomorphic encryption and/or blockchain anchoring where appropriate, to support cross-partner detection, correlation, and prioritisation while maintaining lawful and auditable handling of information.

To ensure interoperability and operational uptake, analytic outputs will be normalised into STIX objects and distributed via TAXII collections segmented by typology and sensitivity, such as pay-in-crypto campaigns, dark-web fraud shops, and wallet cluster signals. A key innovation is coupling intelligence generation with a coordinated public and private response and recovery mechanism aligned with national cyber resilience priorities and UK Government Cyber Action Plan style coordination. The framework will define governance structures including roles, decision rights, service level agreements, escalation paths, and audit trails so shared intelligence can trigger timely and accountable actions such as disruption, for example wallet blocking and takedown requests, safeguarding through victim alerts, and structured recovery workflows.

Methodologically, the project will combine analysis of open-source case studies, OSINT, public blockchain data, and selected dark-web intelligence to derive typologies and baseline indicators, alongside stakeholder engagement through semi-structured interviews across law enforcement, national coordination bodies, and industry. It will then develop and evaluate a proof-of-concept federated socio-technical framework that keeps sensitive data local while enabling privacy-preserving analytics and interoperable intelligence exchange using STIX and TAXII under agreed workflows, roles, and auditability. The framework will be assessed for feasibility, actionability, governance fit, and its impact on timely response and recovery.

The research will be delivered in close collaboration with Aston University’s Cyber Security Innovation (CSI) Research Centre and a strong network of government and industry partners, providing an applied research environment with clear routes to impact, scalable pilots, and follow-on larger projects. This PhD is ideal for students interested in threat intelligence, privacy-preserving AI, and cybercrime disruption who want to help reduce online harms and crypto-enabled crimes.
