Main Idea
BigONE exchange suffered a $27 million hot wallet hack, prompting the exchange to pledge full coverage of losses and collaborate with security firms to recover funds and enhance defenses.
Key Points

3. BigONE is collaborating with security firms SlowMist and Cyvers to trace stolen funds and improve security measures.
4. The hack reflects broader crypto exchange vulnerabilities, with H1 2025 seeing over $2.47B in losses from hacks, scams, and exploits—a 3% YoY increase.
5. The incident follows a $3.5M exploit at Arcadia, highlighting growing concerns over exchange security and the need for stronger operational protocols.
