## RECOMMENDED ACTIONS

Priority: CRITICAL

Immediate Recommendations:

1. Increase logging verbosity and review recent activity from this IP

2. Block at perimeter firewall and WAF layers

3. Monitor for any changes in behavior or service exposure

Firewall Rules:

• iptables: `iptables -A INPUT -s 61.145.212.56 -j DROP`
• nftables: `nft add rule inet filter input ip saddr 61.145.212.56 drop`
• nginx: `deny 61.145.212.56;`
• Cloudflare WAF: Block with expression `ip.src eq 61.145.212.56`
• AWS WAF: Include `61.145.212.56/32` in IP set

Threat Intelligence Note: The combination of high risk score, multiple blacklist listings, and geolocation in a known threat-adjacent region warrants continued monitoring. The lack of service exposure may indicate the IP is used for outbound communications, scanning, or as a command-and-control endpoint.
