### Overview
FIN7 successfully navigated laterally through the network, reaching the payment processing systems. This movement facilitated the exfiltration phase.

### Key Findings
- **Credential Reuse**: Previously compromised credentials were reused to access high-value systems.
- **Network Mapping**: The attackers conducted extensive mapping of the internal network to identify critical assets.

### Next Steps
- **Data Exfiltration Monitoring**: With access to the payment network confirmed, focus on detecting and preventing the exfiltration of credit card information. Implement heightened monitoring of data flows leaving the network perimeter.
