Bybit Says It Blocked $700M in Losses After $1.5B Hack

Bybit says it intercepted more than $700 million in potential user losses during the first half of 2026, a security push that follows the exchange's $1.46 billion theft in February 2025.

The figures came Tuesday in Bybit's H1 2026 Risk & Security Report. The Dubai-based company said its security efforts during the period focused on user and account security, real-time on-chain monitoring, and AI-assisted security operations.

Bybit said it blocked more than 30,000 suspicious withdrawal requests during the first half of the year, protecting nearly 20,000 users from potential losses. Initial risk reviews took an average of 4.7 minutes, with 95% completed within 10 minutes, the company said.

The exchange also identified about $212 million in potentially fraud-linked on-chain funds and blacklisted more than 10,000 malicious addresses, according to the report.

The security push comes after Bybit suffered one of the largest cryptocurrency thefts on record in February 2025, when about $1.46 billion in digital assets was stolen from the exchange.

Since then, Bybit says it has expanded its ability to monitor transactions and respond to threats across its infrastructure.

The exchange said it now monitors 100% of business-relevant on-chain activity, including listed token contracts, ecosystem contracts and its cold, warm and hot wallets.

During the first half of 2026, Bybit said it handled 10 security incidents involving listed token projects without recording losses to the platform. In eight cases, the company said it completed emergency responses before other major exchanges. In two cases, Bybit said it detected the incidents before the affected projects identified the attacks.
