Today, Bybit, the second largest cryptocurrency exchange in global trading volume, officially announced the comprehensive results of its 2025 Security Initiative. Bybit has built an industry-leading multi-layer defense architecture, successfully protecting the safety of tens of thousands of users, and establishing a new benchmark for proactive risk control in the digital asset sector. According to a report by Chainalysis, global cryptocurrency losses due to scams and fraud reached as high as 17 billion dollars in 2025.

Redefining industry standards: Three-tier withdrawal fraud defense framework

To overcome the limitations of traditional post-event risk control, Bybit pioneered a dynamic risk grading protection system that proactively intervenes before financial losses occur. This system categorizes potential scam scenarios into three risk levels, each matched with differentiated response strategies—ensuring the safety of user withdrawals while maintaining a smooth trading experience on the platform.

Level 1: Early Warning (Low Risk)

Leveraging big data heuristic algorithms to identify abnormal behavior patterns (e.g., large withdrawals concentrated to a single new address), Bybit automatically triggers risk questionnaire surveys. Relevant insights assist the risk control operations team in preemptively blacklisting high-risk addresses, achieving source interception.

Level 2: Real-time Warning (Medium Risk)

When an account is flagged due to database collisions (cross-referencing external network leak data) or associated with suspicious withdrawal addresses, Bybit triggers real-time pop-up alerts 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: Instant Interception + Cool-down Period (High Risk)

For wallets confirmed to be involved in scams (including so-called "pig-butchering" investment scams), Bybit implements real-time withdrawal interception and enforces a one-hour cool-down period. This critical time window provides crucial assurance for users to regain rational judgment and verify the authenticity of transactions.

Overview of 2025 Achievements and Core Data

The above measures implemented in the fourth quarter of 2025 brought breakthrough results for user safety protection:

In Q4, fraudulently obtained funds interception and recovery: Bybit successfully intercepted and recovered 300 million dollars through proactive reminders, protecting the life savings of over 4,000 users;

In Q4, AI-driven risk identification: Bybit's self-developed AI algorithm accurately identified 350 high-risk investment scam addresses through on-chain data analysis, helping 8,000 users avoid potential withdrawal losses;

In 2025, the resilience of infrastructure: the platform successfully withstood over 3 million hacker database collision (account hijacking) attacks;

In Q4, proactive on-chain monitoring: the system automatically marked 350 risk addresses, and the ticket operation team manually reviewed and marked 600 addresses, cumulatively avoiding nearly 1 million dollars in immediate fraud losses.

Building a safe ecosystem together: 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 deep integration of external intelligence:

"In 2025, our mission is to upgrade the risk control system from a 'silent shield' to a proactive, intelligent safety guardian," said David Zong, Head of Risk Control at Bybit Group. "By deeply integrating AI-driven on-chain monitoring with real-time intelligence from industry partners like TRM, Elliptic, and Chainalysis, we not only safeguard Bybit users but also assist in mapping the 'genetic blueprint' of fraud networks. We are making these standardized monitoring clues open and shareable with the entire ecosystem—because the security of the industry begins with the security of every participant."
