# IPDEBRIEF INTELLIGENCE BRIEFING

Target: 5.142.217.56/32

Classification: HIGH RISK

Generated: Current Session

---

## EXECUTIVE SUMMARY

IP 5.142.217.56 is a high-risk endpoint (risk score 70/100) associated with Rostelecom (ASN 12389) infrastructure in Russia. The IP is currently firewalled with no active services detected but has been flagged on 4 DNS blacklists out of 8 total lists. The IP demonstrates route instability with 2 BGP route changes in the past 30 days.

## NETWORK CLASSIFICATION

---

## THREAT INDICATORS

• DNSBL Listings: 4/8 total lists flagged
• Route Stability: Unstable (2 changes in 30-day window)
• Blacklist Severity: Maximum severity "high" on multiple lists
• Control Plane: RPKI state not verified; IRR consistency not available

---

## GEOLOCATION & OWNERSHIP

• Organization: Not resolved (ASN 12389 identified as Rostelecom)
• Geolocation: Data insufficient (0 geo sources; geo consensus false)
• PTR Records: Unresolved
• Reverse DNS: None detected

---

## NETWORK BEHAVIOR

• Open Ports: None detected
• TLS/HTTPS: No certificates or HTTP services active
• Honeypot Hits: 0
• Enumeration Strikes: 0
• WAF Violations: 0

---

## NEIGHBORHOOD ANALYSIS (5.142.217.0/24)

• Subnet Classification: Low threat density
• Abuse Density: 0
• Total Siblings: 1 (5.142.217.189)
• Neighbor Risk Profile: Low (risk score 15/100, authority score 50)
• Threat Siblings: 0

The target IP operates in a low-abuse-density subnet with minimal neighboring threat activity, suggesting isolated malicious behavior rather than coordinated subnet compromise.

---

## OBSERVATION HISTORY

• Total Observations: 10 signals in recent monitoring period
• Recent Activity: Elevated listing activity as of 2026-07-29 (8 total lists, 4 active listings with high severity)
• DNSSEC Status: Valid (RRSIG present)
• Persistence: No persistent malicious indicators detected

---

## RECOMMENDED ACTIONS

IMMEDIATE: Monitoring Enhancement

• Increase logging verbosity for traffic from 5.142.217.56
• Review recent activity patterns and connection attempts

FIREWALL RULES (Recommended)

---

## INTELLIGENCE NOTES

1. Risk Context: Despite high risk score, no active threat indicators or known campaigns detected. Risk elevation primarily driven by DNSBL listings and route instability.

2. Infrastructure Assessment: No evidence of hosting, proxy, CDN, or VPN services. The IP appears to be a firewalled endpoint rather than an active attack infrastructure component.

3. SOC Priority: Monitor for activity increase or service activation. Current profile suggests reconnaissance or dormant endpoint rather than active exploitation.

4. Correlation Opportunity: No external relationships detected; no certificate matches or correlated IPs identified in relationship graph.
