Bybit releases 2025 security milestone: relying on a new AI driven risk framework, intercepts fraudulent funds of up to $300 million Bybit, the world's second-largest cryptocurrency exchange by trading volume, officially announced the comprehensive results of its 2025 Security Initiative today. Bybit has built an industry-leading multi-layer defense architecture, successfully protecting the security of tens of thousands of users and setting a new benchmark for proactive risk control in the field of digital assets. According to a Chainalysis report, the global cryptocurrency losses caused by fraud and scams will reach $17 billion by 2025. Reshaping industry standards: The three-tier withdrawal fraud defense framework breaks through the traditional risk control limitations of "post remediation". Bybit has pioneered a dynamic risk grading protection system that actively intervenes before financial losses occur. The system divides potential fraud scenarios into three risk levels, each matched with differentiated response strategies - ensuring the safety of user withdrawals while ensuring a smooth and unobstructed trading experience on the platform. Level 1: Early warning (low-risk) relies on big data heuristic algorithms to identify abnormal behavior patterns (such as large withdrawals to a single new address), and Bybit automatically triggers risk questionnaire surveys. Relevant insights help the risk control operation team to blacklist high-risk addresses in advance and achieve source interception. Level 2: Real time warning (medium risk) When an account is identified due to collision with database tags (cross referencing external network leaked data) or association with suspicious withdrawal addresses, Bybit will trigger a real-time pop-up reminder during the withdrawal process. This mechanism guides users to pause operations and review transaction details, effectively resisting social engineering attacks that rely on urgency or emotional pressure. Level 3: Real time interception+cooling off period (high-risk) Bybit implements real-time withdrawal interception and enforces a 1-hour cooling off period mechanism for wallet addresses confirmed to be involved in fraud (including so-called "pig killing" investment scams). This critical time window provides important guarantees for users to restore rational judgment and double check the authenticity of transactions. The above measures implemented in the fourth quarter of 2025 have brought breakthrough results to user security protection: Q4 fraud fund interception and recovery: Bybit successfully intercepted and recovered $300 million through proactive reminders, safeguarding the life savings of over 4000 users; Q4 AI driven risk identification: Bybit's self-developed AI algorithm accurately identified 350 high-risk investment fraud addresses through on chain data analysis, helping 8000 users avoid potential withdrawal losses; Infrastructure resilience for the whole year of 2025: The platform successfully withstood over 3 million hacker attacks (account hijacking); Proactive monitoring on the Q4 chain: The system automatically marked 350 risk addresses, and the work order operation team manually reviewed and marked 600 addresses, avoiding nearly $1 million in instant fraud losses. Building a secure ecosystem: Industry collaboration and government enterprise linkage. Bybit firmly believes that security should not be a competitive barrier, but a shared responsibility of the entire industry. The strategic focus for 2025 is on the deep integration of external intelligence: "By 2025, our mission is to upgrade our risk control system from a 'silent shield' to an active and intelligent security guardian," said David Zong, Risk Control Head of Bybit Group. "By deeply integrating AI driven on chain monitoring with real-time intelligence from industry partners such as TRM, Elliptic, Chainalysis, etc., we not only protect Bybit users, but also help draw the 'genetic map' of fraud networks. We are opening up and sharing these standardized monitoring clues throughout the entire ecosystem - because the safety of the industry begins with the safety of every participant. "
