## OBSERVATION HISTORY
Total Observations: 22 signals collected
Recent activity shows:
- June 20, 2026: Operator score 0.2174 (Minimal), 3 signals detected
- June 15, 2026: Subnet abuse density signal (0.6055, high_abuse classification)
- Geolocation Validation: RTT violation detected (27ms observed vs. 121.6ms minimum possible for 6082km distance), indicating potential geolocation spoofing or routing anomalies
No persistent malicious activity detected over observation period.
---
## RELATIONSHIP ANALYSIS
The IP maintains 37 relationship records, primarily mapping to the same network assignment (OVH-CUST-281059688). No direct relationships to external hostnames, organizations, or certificates beyond network-level associations.
---
## ACTIONABLE RECOMMENDATIONS
For SOC Analysts
1. Monitor, not block immediately โ Moderate risk score with no active threat indicators
2. Investigate subnet context โ 155 threat siblings in /24 may indicate broader compromise
3. Validate geolocation claims โ Significant RTT violation suggests potential spoofing or misattribution
4. Monitor DNS activity โ Single DNSBL listing warrants observation for campaign correlation
Firewall/Network Recommendations
- Allow traffic if legitimate business need exists (Ahrefs-associated domain)
- No immediate blocking required based on current risk profile
- Consider monitoring for outbound connections from this IP to known C2 infrastructure
---
## CONFIDENCE LEVELS
- Ownership Attribution: High confidence (OVH network assignment confirmed)
- Risk Scoring: Medium confidence (single observation point)
- Geolocation: Low confidence (RTT violation detected)
- Threat Status: Medium confidence (subnet-level indicators present, IP-level clean)
