Quick Summary On November 3, 2024, MetaWin, a prominent online crypto casino, suffered a security breach that resulted in the loss of approximately $4 million. Details of the Exploit The breach at MetaWin exploited the platform’s instant withdrawal mechanism, which was designed for seamless and rapid transactions. This "frictionless" system inadvertently allowed a hacker to bypass traditional security checks, gaining access to the casino’s Ethereum and Solana hot wallets. Hot wallets, which remain online for quick transaction processing, are inherently more vulnerable, and this became the critical entry point for the attack. Upon detecting the intrusion, MetaWin swiftly disabled withdrawals to secure the system. However, the damage was already done, with over $4 million drained from the platform. The hacker’s method involved targeting addresses directly linked to the withdrawal system, using a sophisticated approach that leveraged over 115 addresses. Blockchain expert ZachXBT collaborated with MetaWin to trace the stolen assets, revealing that the hacker funneled the funds through KuCoin and HitBTC, platforms often utilized for obfuscating the origin of stolen funds.
