Bybit Cryptocurrency Exchange Prevents $ 300 Million in Hacker Attacks

Crypto exchange Bybit has announced the results of its security initiative for 2025: the company intercepted and recovered $ 300 million that could have been lost due to fraudulent schemes and unauthorized withdrawals. This was stated in an official announcement on February 27.

According to the exchange, in 2025, global losses from crypto scams and fraud reached $ 17 billion (Chainalysis estimate). To counteract the risks, Bybit has introduced a multi-level security system that analyzes transactions during withdrawals and blocks suspicious transactions.

The system operates on a three-tiered model: at a low risk level, automatic analysis and blocking of addresses is applied, at an average level, the user receives a real-time warning, and in case of high risk (for example, confirmed fraudulent wallets), transactions are blocked with an hour-long «pause» before possible re-confirmation.

In the fourth quarter of 2025, Bybit intercepted $ 300 million of $ 500 million in suspicious withdrawals, protecting more than 4,000 users. The system also identified 350 high-risk addresses, which prevented losses for another 8,000 customers. In addition, the exchange blocked more than 3 million hacking attempts through «credential stuffing» and helped freeze assets worth $ 4.32 million for 335 victims.

The company emphasized that its strategy is based on cooperation with leading analytical platforms TRM, Elliptic, and Chainalysis. «We have transformed risk control from a 'silent shield' to an active intelligent defender,» said David Zong, Bybit’s chief risk officer. The exchange plans to continue to develop proactive protection methods and share data to improve the security of the entire industry.
