Historical Observation Timeline (18 Observations)

Recent activity confirms subnet-level abuse classification (confidence: 0.75) observed on 2026-06-05. Multiple signals indicate consistent abuse patterns across the /24 block. Geolocation signals show AU and Singapore attributions with low confidence (0.28–0.30), supporting the geo-validation anomaly.

Recommended Security Actions

Immediate Mitigation:

• iptables: `iptables -A INPUT -s 45.133.5.183 -j DROP`
• nftables: `nft add rule inet filter input ip saddr 45.133.5.183 drop`
• nginx: `deny 45.133.5.183;`
• pfSense: `45.133.5.183/32`

Extended Blocking (Cloudflare/AWS WAF):

• Block IP 45.133.5.183/32 with description "IPDebrief risk 40"

Contextual Recommendation: Consider subnet-level blocking (45.133.5.0/24) given 81% threat sibling density and high-abuse classification, though this will affect legitimate traffic within the provider block.

Intelligence Notes

1. Geo-Location Discrepancy: IP reports AU location but RTT metrics and coordinate data indicate Singapore placement — potential VPN/proxy misrepresentation.

2. Subnet Risk: High-abuse environment (0.8077 density) suggests provider may be compromised or misconfigured for residential/VPN services.

3. No Active Services: Firewall configuration prevents service enumeration; threat indicators rely on passive reputation feeds.

4. Action Priority: Moderate — block at perimeter, monitor for subnet-wide activity patterns.
