SBI Crypto confirms $21 million devastating theft as attackers target mining infrastructure ...

This article by blockchain investigators examines the September 2025 cyber attack that drained $21 million from SBI Crypto's mining infrastructure, revealing a strategic shift in cryptocurrency theft tactics. The case demonstrates how attackers moved beyond traditional exchange targets to exploit the centralized vulnerabilities within mining pool operations, where thousands of miners combine computing power and share rewards through coordinated systems.

• Attackers targeted mining infrastructure directly rather than custodial exchanges, gaining control over reward distribution systems to redirect payouts to their own wallets
• The heist involved multiple cryptocurrencies including Bitcoin, Ethereum, and Litecoin, with funds quickly laundered through mixing services and instant exchanges
• Security analysts link the attack patterns to North Korean cyber operations, showing an evolution from exchange-focused thefts to targeting critical cryptocurrency infrastructure
• Mining pools present attractive targets due to their centralization of computing power and financial flows, often operating with minimal security checks to maintain operational efficiency
