- Check Mobile Carrier Logs: Collaborate with KT to validate the IP’s legitimacy and check for unusual mobile network activity.
Actionable Rules:
- Firewall: Block 218.149.228.145/32 (e.g., `iptables -A INPUT -s 218.149.228.145/32 -j DROP`).
- SIEM Alert: Trigger alerts for traffic originating from this subnet (218.149.228.0/24).
