IP Intelligence Briefing: 5.167.65.24

Date: 2026-06-08

---

**1. Risk Profile**

• Overall Risk Score: 59 (Moderate Risk)
• Threat Indicators:

- Listed on blocklist.de (malicious activity detected).

- Marked as a known attacker in threat feeds.

• Network Classification: Residential endpoint (ER-Telecom, Russia).
• Geolocation:

- Located in Cheboksary, Chuvash Republic, Russia (RU).

- ICMP validation failed (potential obfuscation or firewall blocking).

---

**2. Network Context**

• ISP/Organization: ER-Telecom (ASN 57026).
• Subnet: 5.167.65.24/24.
• Neighborhood Risk:

- Subnet abuse density: 0% (low-risk neighborhood).

- 100 IPs in subnet, with 40 average risk score (mostly low/medium).

- No high-risk neighbors detected.

---

**3. Historical Observations**

• Signal Stability:

- Consistent "Minimal" risk score (0.15–0.60 confidence) over 47 observations.

- No recent spikes in threat activity or DNS anomalies.

• GeoValidation:

- ICMP blocked; location accuracy uncertain.

---

**4. Relationships & Dependencies**

• Linked Networks:

- Part of ERTH-CHEB-PPPOE-22-NET (residential broadband segment).

• Domain Associations:

- PTR hostname: `5x167x65x24.dynamic.cheb.ertelecom.ru` (ERTelecom domain).

- SPF/DKIM records present but unverified.

---

**5. Actionable Insights**

• Threat Vector:

- IP flagged as a known attacker; monitor for C2 activity, scanning, or data exfiltration.

• Network Segmentation:

- Residing in a low-risk subnet but with a moderate-risk host—consider isolating or monitoring the segment.

• SOC Recommendations:

- Block the IP in firewalls (iptables/nftables) to mitigate potential threats.

- Investigate if the IP is part of a larger compromised network (e.g., botnet, phishing infrastructure).

- Validate geolocation using alternative methods (e.g., TLS fingerprints, TLSA records).

---

Next Steps:

• Correlate with internal threat intel for known campaigns.
• Check for associated domains or certificates in the ERTelecom ecosystem.
• Monitor for lateral movement or subnet-wide compromises.

Confidence: Moderate (limited geo-validation, but threat feeds indicate malicious activity).
