---
**1. Profile Summary**
- Risk Score: Moderate (55/100)
- Ownership: Registered to T. R. TELECOMUNICACOES LTDA (Brazil, ASN 270368).
- Geolocation: Brazil (SP, Votuporanga), but geo-validation flags inconsistency (RTT discrepancy suggests potential misconfiguration or routing anomalies).
- Network Role: Web server (ports 80, 443, 22 open; lighttpd/1.4.39).
- Threat Indicators: No direct malicious activity detected. Listed in 3/8 DNSBLs (potential spam or abuse risk).
---
**2. Observation History**
- Recent Activity:
- 2026-06-06: Connection failures to HTTPS (confidence 0.30).
- 2026-05-29: BGP route stability confirmed (AS270368, route changes: 0).
- No persistent threats or campaign correlations.
---
**3. Relationships**
- Linked Entities:
- Same network (AS270368, 190.89.137.0/24).
- No direct links to organizations, hostnames, or certificates.
---
**4. Neighborhood Analysis**
- Subnet: 190.89.137.0/24 (abuse density: 22%).
- Neighbor Risk:
- 22 high-risk IPs, 69 medium-risk IPs, 9 low-risk IPs.
- Notable: 190.89.137.1–4 (riskScore 55), 190.89.137.9 (riskScore 20).
- Subnet Classification: Mixed (legitimate and potential abuse).
---
**5. Threat Assessment**
- Likelihood: Low to moderate risk.
- Indicators:
- DNSBL listings (3/8) suggest potential spam or abuse.
- Geo-validation anomalies may indicate misconfiguration or spoofing.
- Neighboring IPs show a 22% abuse density, warranting subnet-level monitoring.
- Recommendations:
- Investigate DNSBL listings (e.g., Spamhaus, Barracuda).
- Monitor for unexpected traffic patterns or port activity.
- Validate geolocation data to rule out routing anomalies.
---
Next Steps:
- Cross-check DNSBL entries with threat intelligence feeds.
- Analyze neighbor IPs for potential lateral movement or network compromise.
- Ensure web server (lighttpd) is patched and configured securely.
