Abstract

Worldwide media is reporting an alarming increase in cyber-attacks targeting critical infrastructure systems, posing a significant threat to national security and financial stability. The tight dependency between various systems like financial institutions, companies supplying assorted services, healthcare or education, makes cyberattacks, a formidable weapon that can affect nation-wide infrastructures. Illicit activities (money laundering, fraud, terrorist financing, sanctions evasion) may have the same impact on nationwide infrastructures, as a large scale cyberattack. The paper proposes the usage of blockchain technology for data collection and analysis, to serve as an early warning system for public and private organisations, in both cases – cyberattacks or associated illicit activities, like money laundering, crypto tumblers or black markets. Blockchain can be the core for an ecosystem of contributors for various cybersecurity services suppliers and sources, easing real-time detection, reporting, and alerts on high-risk activities
