Recommendations
- Block IP address 216.180.246.151 at perimeter firewalls unless legitimate business relationship exists
- Implement enhanced logging and alerting for administrative interface access attempts (/admin/* paths)
- Review and harden administrative login pages with multi-factor authentication and IP allowlisting
- Monitor for follow-on credential brute force attempts against identified administrative interfaces
- Correlate this reconnaissance activity with subsequent authentication logs to identify potential compromise attempts
