Abstract:

This paper examines the growing threat of crypto-enabled espionage and its impact on national security. The research addresses the central question how cryptocurrencies facilitate espionage, and what are the implications for national security. Using a qualitative approach, the study draws on existing literature, case studies, and intelligence reports to explore how cryptocurrencies are increasingly being leveraged by state and non-state actors for covert operations. The findings reveal that the key features of cryptocurrencies—such as anonymity, decentralization, and the lack of regulation make them highly attractive to espionage actors. Specific cases, including the use of cryptocurrencies by North Korean and Russian state sponsored espionage networks, demonstrate how these actors bypass financial surveillance systems. The study concludes that while cryptocurrencies offer significant advantages for espionage, they pose severe challenges for national security agencies, especially in terms of monitoring and preventing illicit activities. To address these threats, stronger international cooperation, regulatory reforms, and advancements in blockchain surveillance technology are necessary. The paper recommends further research into counterintelligence strategies that incorporate blockchain technology and artificial intelligence for monitoring crypto-enabled espionage.
