This article provides a detailed compilation and analysis of several security incidents involving centralized crypto asset exchanges throughout history. From the Mt. Gox incident in 2014 to the Bybit theft in 2025, hackers have repeatedly stolen assets from exchanges through means such as hot wallet vulnerabilities, improper key management, and smart contract bugs, resulting in significant losses. These incidents demonstrate that crypto exchanges face complex security threats and must continuously innovate security technologies, strengthen measures such as cold wallet protection, smart contract audits, and multi-signature mechanisms. Additionally, cooperation and transparency within the industry are crucial, as demonstrated by Gate.io's enhancement of asset security through high reserve ratios and zero-knowledge proof technology. In the future, exchanges need to adopt more cutting-edge technologies such as artificial intelligence and blockchain analysis to enhance their security capabilities.
