INFORMATION SECURITY IN CRYPTO MONEY EXCHANGE

In recent years, cryptocurrencies have gained significant ground as an alternative investment andvalue transfer tool in the global financial system. Given the increasing popularity of these digitalassets, cryptocurrency exchanges have also come to play a central role for both individual andinstitutional investors. However, this growth has also given rise to significant information securityconcerns. In particular, the aggregation of user funds on centralized exchanges renders theseplatforms susceptible to cyberattacks. This study analyzes the primary information security threatsfaced by cryptocurrency exchanges. The text delves into a range of cyberattacks, includingphishing, DDoS (Distributed Denial of Service) attacks, 51% attacks, API vulnerabilities, internalthreats, and user-induced errors. It then proceeds to assess the impact of these threats on exchanges.The practical consequences of these threats are illustrated through case studies of Mt. Gox,Coincheck, Binance, KuCoin, and Thodex. Furthermore, the study assesses the primary securitymeasures implemented by cryptocurrency exchanges. The following practices are discussed interms of their contribution to information security: cold wallet usage, multi-factor authentication(2FA), Know Your Customer (KYC)/Anti-Money Laundering (AML) policies, and smart contractaudits. The findings indicate that, in addition to technical measures, user awareness, regulatoryoversight, and continuous risk analysis processes are also of critical importance.
