## Lessons Learned
- State-sponsored actors (Lazarus Group, etc.) pose a continuing, high-level threat to cryptocurrency platforms.
- Security controls around high-value asset custody (hot/warm wallets) must be constantly vetted against sophisticated threat actor TTPs.
## Recommendations
- Implement enhanced multi-factor authentication (MFA) for all administrative access, specifically for key management systems.
- Increase proactive threat hunting focused on indicators associated with North Korean Advanced Persistent Threats (APTs).
- Review and segment internal networks controlling critical financial infrastructure to limit the blast radius of any potential perimeter breach.
