Cryptocurrency exchange BigONE has announced a $27 million loss following a security breach targeting its hot wallet infrastructure. The incident compromised significant holdings across multiple cryptocurrencies, including Bitcoin (BTC), Ethereum (ETH), Solana (SOL), Dogecoin (DOGE), and Shiba Inu (SHIB).
In response, BigONE has engaged blockchain security firm SlowMist to trace and recover the stolen assets. The exchange confirmed the breach has been contained, with no further unauthorized withdrawals detected since mitigation efforts began.
BigONE has publicly committed to fully reimbursing all affected users from company reserves and is implementing enhanced security protocols to fortify its systems against future attacks.
This breach adds to a series of major cryptocurrency exchange security incidents in 2025, with combined losses including Bybit ($1.5 billion), Phemex ($85 million), Cetus Protocol ($225 million), Infini ($49 million), and Moby ($2.5 million).
The recurring pattern underscores systemic security vulnerabilities within the digital asset ecosystem, highlighting the urgent need for exchanges to adopt more robust protective measures and comprehensive risk management frameworks.
