- **What could have been done better:** Implementing stronger multi-factor authentication or hardware security modules (HSMs) for high-value asset transfers.
## Recommendations
- Implement strict separation between cold storage and hot wallets, ensuring hot wallets only contain necessary operational liquidity.
- Review and potentially overhaul key management and access controls for withdrawal functions.
- Enhance real-time transaction monitoring systems to flag unusual withdrawal volumes or destinations immediately.
