IP Intelligence Briefing: 54.39.203.49
Date: 2026-06-15
---
**1. Risk Profile**
- Risk Score: Moderate (50/100)
- Provider: OVH (ASN 16276)
- Network Role: Cloud Compute (OVH infrastructure)
- Geolocation: Canada (QC, Beauharnois) – flagged as geographically implausible due to RTT anomaly (28ms vs. expected 112.6ms for 5,629km).
---
**2. Threat Indicators**
- No direct malicious indicators (no malware, phishing, or known campaigns).
- DNS Association: Linked to `proxy-ca008-san49.ahrefs.net` (Ahrefs Pte Ltd).
- Network Scans: Detected 20+ scans over 6 days (ports, TLS, HTTP).
- Abuse Density: Subnet (`54.39.203.0/24`) shows 52.55% abuse density, with 134/255 IPs flagged as malicious.
---
**3. Network Relationships**
- Same Network: Part of OVH-CUST-281059687 (255 IPs).
- High-Risk Neighbors: 95 IPs in subnet scored ≥40, with 5 low-risk IPs.
- DNS: Resolves to `ahrefs.net` (CAA records present, DNSSEC valid).
---
**4. Observation History**
- Scan Activity: 20+ scans detected (June 9–15, 2026).
- Geo Validation: RTT discrepancy suggests potential spoofing or proxy use.
- Stability: Subnet shows unstable routing (route changes in last 30 days).
---
**5. Recommendations**
- Monitor Traffic: Block or monitor traffic from this IP due to moderate risk and subnet abuse density.
- Verify Geolocation: Investigate spoofed RTT anomalies for potential proxy or MITM activity.
- Check DNS: Ensure `ahrefs.net` is not associated with malicious campaigns.
- Firewall Rules: Add rule to block traffic from `54.39.203.49/32` if not explicitly allowed.
Next Steps: Correlate with internal logs for signs of exploitation or lateral movement.
