### Background
After the initial detection of suspicious activity in the Contact Importer, our team has observed unauthorized script executions interacting with Facebook's APIs.

### Key Findings
- **Script Origin**: The scripts originate from multiple IP addresses, primarily located in Eastern Europe.
- **API Calls**: The scripts are making repetitive API calls to the Contact Importer function, indicating attempts to exploit the vulnerability further.
- **Obfuscation Techniques**: Code analysis reveals the use of obfuscation methods to conceal malicious activity.

### Recommendations
- Immediate review and patching of API endpoints to prevent further exploitation.
- Implement rate limiting and additional verification steps for API interactions.

### Next Steps
Prepare for potential credential stuffing activities, as compromised data could be used to gain persistent access.
