• pfSense: `177.174.125.183/32`
• Cloudflare WAF: Block with filter `ip.src eq 177.174.125.183`
• AWS WAF: Include `177.174.125.183/32` in IP set

## INTELLIGENCE CONTEXT

This IP represents a high-risk endpoint within a legitimate Brazilian mobile carrier infrastructure. The elevated risk score, combined with multiple DNSBL listings and geolocation validation failures, suggests the IP may be compromised or misconfigured. The SSH service running on an older OpenSSH version (6.7) represents an additional security concern. The IP appears to be part of a residential or single-service host configuration rather than typical datacenter infrastructure.

Recommendation: Treat as confirmed threat requiring immediate blocking. Monitor for associated IPs in the 177.172.0.0/14 block showing similar patterns.
