Bybit says its security systems prevented more than $700 million in potential user losses during the first half of 2026, as the crypto exchange continued strengthening its defenses following the massive $1.46 billion hack it suffered in 2025.
According to Bybit’s latest security report, the exchange blocked more than 30,000 suspicious withdrawal attempts between January and mid-June, helping protect nearly 20,000 users. The company said most security reviews were completed within minutes, allowing threats to be identified and stopped quickly.
The exchange also detected around $212 million in funds that may have been linked to fraudulent activity and added more than 10,000 suspicious blockchain addresses to its blacklist.
A major focus for Bybit has been expanding its monitoring capabilities. The company says it now tracks all blockchain activity relevant to its operations, including listed tokens, ecosystem contracts, and its own wallets. During the reporting period, security teams handled 10 incidents involving token projects listed on the platform, and Bybit reported that none resulted in losses for the exchange.
Artificial intelligence has also become a key part of Bybit’s security strategy. The company said AI-assisted systems helped analyze more than 100,000 security alerts during the first half of the year. Automated tools also sped up security testing, reducing some assessment cycles from two weeks to just a few hours.
Bybit says AI is mainly used to identify risks and process large amounts of information quickly, while human security experts continue to make important decisions and oversee critical actions.
The company has been rebuilding and improving its security systems since February 2025, when hackers stole approximately $1.46 billion worth of Ethereum from one of its cold wallets. The attack became the largest cryptocurrency theft on record and was later linked by U.S. authorities to North Korea’s Lazarus Group.
Alongside technical security upgrades, Bybit is also pursuing legal action to recover stolen assets. Earlier this month, the exchange filed a lawsuit in the United States against North Korea, its intelligence agency, and the Lazarus Group over the 2025 attack.
Bybit says protecting users remains its top priority as cyber threats continue to evolve. The company believes faster detection, stronger monitoring, AI-powered tools, and cooperation with law enforcement will play an important role in defending against future attacks.
