Threat Intelligence Briefing: IP 210.13.99.66/32
Summary:
The IP address 210.13.99.66/32 is registered to yanling ruan under ASN 9929 (China Unicom) and geolocated to Shanghai, China. While its network role is classified as mobile (LTE/5G), it shows no direct malicious indicators (e.g., no malware, phishing, or C2 activity). However, the IP exhibits high risk (risk score: 80) due to potential network anomalies and a subnetwork abuse density of 1.
Key Findings:
1. Network Profile:
- Provider: China Unicom (MCC 460, MNC 01).
- Subnet: 210.13.99.66/24, classified as "mostly_clean" but with inherited risk (score: 2).
- BGP Data: Route origin ASN 9929, no recent route changes (30-day stability).
2. Threat Indicators:
- No direct malicious activity detected (no malware, phishing, or C2 signals).
- DNSSEC is valid, but DNS resolution errors occurred (timed out).
- No TLS certificates or open ports identified.
3. Behavioral Trends:
- Observed on 2026-06-03 with low confidence (0.3โ0.6) in threat signals.
- Historical data suggests minimal persistence (0 threat persistence days).
4. Relationships:
- Linked to SH-LEIJIESI network (same ASN, region).
- No active neighbors identified in the subnet.
Recommendations:
- Monitor for unexpected DNS resolution or network behavior changes.
- Investigate potential misconfigurations in DNSSEC or routing policies.
- Correlate with other IPs in the 210.13.96.0/20 prefix for broader network analysis.
Next Steps:
- Use `ipdebrief_actions` to generate firewall rules for further segmentation.
- Validate geolocation accuracy, as coordinates and timezone are unverified.
Risk Level: High (80/100) | Confidence: Moderate (0.27โ0.6).
*Note: No immediate mitigation actions required, but continuous monitoring is advised due to high risk profile and unclear network context.*
