### Overview
Once the custom malware was deployed, the Lazarus Group focused on establishing persistence within the Bangladesh Bank network. This report delves into the techniques used to maintain long-term access.

### Key Findings
- **Backdoor Creation**: Multiple backdoors were installed, providing redundant access points.
- **Registry Manipulation**: Modified system registries to ensure malware execution upon system startup.
- **Credential Harvesting**: Captured administrator credentials to facilitate uninterrupted access.

### Implications
Establishing persistence allowed the attackers to operate undetected over an extended period, crucial for planning the heist's next phases, including lateral movement.
