106.75.25.139
Threat Intelligence Briefing: IP 106.75.25.139/32
Overview:
- Risk Profile: High-risk IP (risk score: 80), flagged for potential abuse.
- Ownership: Registered to Jinhui Jia (ASN 23724), with abuse contact available via RDAP.
- Geolocation: Located in China (CN), but no specific city or region identified.
- Network Role: Firewalled with no open services detected; classified as non-cloud, non-CDN, and non-residential.
Threat Indicators:
- DNSBL Listings: Identified in 4 out of 8 DNSBL feeds (e.g., Spamhaus, Project Honey Pot).
- Behavioral Anomalies: Observed in 17 signals over 30 days, including minimal DNSSEC validation and low geolocation accuracy.
- Incomplete Threat Narrative: One observation flagged the IP as "associated with threat" but lacked detailed campaign or malware correlations.
Network Relationships:
- Subnet: Part of 106.75.25.0/24, with 100% abuse density (1 malicious sibling IP).
- Provider: Linked to UCLOUD-NET (ASN 23724), suggesting potential ties to a Chinese hosting or CDN provider.
Observation History:
- Recent Activity (2026-06-10): Flagged for spam-related DNSBL listings (4 lists) with "high" severity.
- Stability: BGP route instability detected; route changes over 30 days suggest potential network manipulation.
Recommendations:
1. Block the IP: Implement firewall rules (e.g., iptables, Cloudflare WAF) to restrict access.
2. Monitor Subnet: Investigate the 106.75.25.0/24 subnet for additional compromised hosts.
3. Verify Ownership: Cross-check Jinhui Jia's ASN (23724) with WHOIS and abuse reports.
4. Deep Dive: Scrutinize the incomplete threat narrative for potential malware campaigns or phishing activity.
Note: Inconsistent data in the threat narrative and limited neighbor activity suggest the IP may be a static or isolated host. Further analysis of DNS and TLS records is advised.
