- Geolocation:
- Country: Canada (QC, Beauharnois)
- Geo Plausibility: ❌ *Unlikely* (RTT anomaly: 24ms vs. expected 112.6ms for 5,629km)
- Network Role: Hosting provider (OVH)
- Threat Indicators: No malicious indicators, no blacklisted domains, no spam sources.
---
**2. Network Behavior**
- Subnet: 54.39.203.96/24
- Subnet Risk: High abuse density (0.504), 126 threat siblings out of 250 total IPs.
- Neighbor Analysis:
- 93% of subnet IPs flagged as medium-risk (score 40–50), 7% low-risk.
- No direct peer relationships identified.

**3. Anomalies & Observations**
- RTT Discrepancy:
- Geo validation shows RTT of 24ms, which is inconsistent with the 5,629km distance.
- Likely spoofed or non-residential IP.
- DNS Configuration:
- PTR record resolves to `proxy-ca008-san96.ahrefs.net` (Ahrefs domain).
- No email authentication (SPF/DKIM) detected.
- BGP & DNSSEC:
- Valid DNSSEC, CAA records present.
- BGP prefix `54.39.0.0/16` shows no route stability.
---
**4. Threat Context**
- No Direct Threats: No malware, C2, or exploit indicators.
- Subnet Risk: High abuse density suggests potential for lateral movement or shared hosting compromises.
- Hosting Provider: OVH is a legitimate cloud provider, but shared hosting environments may host malicious activity.
---
**5. SOC Recommendations**
1. Monitor Subnet Traffic: Track 54.39.203.0/24 for unusual outbound connections or data exfiltration patterns.
2. Verify Geolocation: Investigate the RTT anomaly to rule out spoofing or misconfigured infrastructure.
3. Inspect DNS Behavior: Ensure DNS resolution for `proxy-ca008-san96.ahrefs.net` is legitimate and not used for command-and-control.
4. Check Hosting Environment: Confirm Ahrefs’ compliance with shared hosting security standards.
