Botha, Johannes GBerkman, ALeenen, L2026-07-272026-07-272026-06http://hdl.handle.net/10204/14860This paper presents a follow-up study to earlier research on cryptocurrency crime, again drawing on the case of an elderly woman defrauded by an online platform known as RSI-Platform. Whereas the initial study focused mainly on on-chain analysis within the blockchain environment, the present work shifts attention to off-chain approaches, applying open-source intelligence (OSINT) techniques to deepen investigations into crypto-related fraud. By systematically examining diverse input data—such as names, phone numbers, email addresses, and URLs—this study conducts link analysis and aims to build detailed profiles of potential suspects, thereby advancing understanding of the strategies and methods used in cryptocurrency scams. The analysis aims not only to trace the scammers’ digital footprints but also to reveal networks and connections to other fraudulent platforms that support these activities. Moreover, this research seeks to raise public awareness about the scale and operation of fake online investment schemes in the crypto sector. By exposing the vulnerabilities exploited by offenders and illustrating how OSINT can be used to detect and disrupt such scams, the paper adds to ongoing discussions on cybersecurity and consumer protection in the fast-changing field of digital finance. Additionally, the findings are intended to offer practical insights for law enforcement agencies, policymakers, and the wider public, encouraging a more informed and proactive response to the threats posed by crypto-related fraud.FulltextenCybercrimeCybercrime investigationsCryptocurrency scamsFake investmentsOpen-source intelligenceOSINTConference Presentationn/a
