Bybit's Fraud Prevention System Stops $300 Million in Risky Withdrawals

By: Isha Das

In the fourth quarter of 2025, the cryptocurrency exchange Bybit successfully blocked over $300 million in potentially fraudulent withdrawals, largely attributed to the implementation of their new AI-assisted risk monitoring system. This system is designed to identify and flag malicious transactions before the funds leave the exchange. This significant development marks a shift from merely reacting to fraud after it occurs to adopting a more proactive approach to prevent illicit activities.

According to Bybit, the system flagged about $500 million in withdrawal requests during the quarter, offering protection to over 4,000 users by issuing real-time risk alerts or blocking transactions outright. This innovative fraud prevention mechanism not only prevents money from being siphoned off by fraudsters but also provides users with the necessary information to reconsider potentially risky transactions. Bybit's head of group risk control, David Zong, highlighted that the majority of the $300 million in "saved" transactions were voluntarily canceled by users after they received alerts, ensuring the funds remained in their accounts without requiring further interventions.

This proactive measure by Bybit showcases a growing trend among cryptocurrency exchanges to strengthen security systems and enhance user trust amid rising threats from impersonation scams and other fraudulent activities. The integration of advanced technologies such as AI for on-chain monitoring illustrates the industry's commitment to developing robust defenses against thefts and scams. Additionally, the success of Bybit's system paves the way for similar approaches that can offer increased protection to users, potentially reducing the billions lost to crypto fraud each year.

In another notable crime involving cryptocurrency, an ex-LAPD officer was found guilty of robbing $350,000 in bitcoin through a violent "wrench attack," emphasizing the persistent risks individuals face within the crypto space. The case serves as a reminder of the diverse threat vectors, underscoring the need for comprehensive security, not only at the institutional level but also for individual investors and traders.
