BigONE Platform Hit by Security Breach: Unauthorized Access Compromises Hot Wallet Infrastructure

BlockBeats reported on July 16 that BigONE, a digital trading platform, announced a significant security incident affecting its hot wallet infrastructure. The unauthorized access has triggered immediate corrective action from the platform management.

Swift Response and User Protection Measures

Following the discovery of the breach, BigONE moved rapidly to protect user interests. The platform has committed to assuming full financial responsibility for any losses stemming from this unauthorized access incident. While trading and deposit operations have been temporarily suspended for security assessment, the platform assured users that withdrawal services would resume once comprehensive security upgrades are completed.

Technical Details of the Incident

According to monitoring data from Slow Mist, the breach resulted from a supply chain attack targeting BigONE’s production infrastructure. Security analysts discovered that threat actors gained unauthorized access and modified critical operational logic associated with account management and risk control systems. This modification enabled unauthorized fund transfers from the platform.

Despite the severity of the compromise, investigators confirmed that the attackers did not obtain access to the platform’s private key infrastructure, which limited the scope of potential damage.

Impact Assessment

The incident resulted in confirmed losses exceeding 27 million USD. However, given BigONE’s commitment to cover all losses from this unauthorized access event, the direct financial impact to individual users should be mitigated pending full reimbursement processing.

Path Forward

The platform continues working on security infrastructure reinforcement before restoring full operational capacity. Users are advised to monitor official announcements for updates on service restoration timelines.
