*Generated via IPDebrief tools: Profile, History, Relationships, Neighbors*

---

**1. Core Profile**

• Risk Score: 25 (Low Risk)
• Ownership: Microsoft Corporation (ASN 8075, ARIN registry)
• Geolocation: Virginia, VA, US (36.67°N, -78.93°E)
• Network Role: Microsoft Azure cloud infrastructure (Firewalled / No Services)
• Threat Indicators: No malicious activity, no blacklist entries, no known attacker campaigns.

---

**2. Observation History**

• Stability: No significant changes in risk signals over time.
• Consistency: Geolocation and DNS records remain stable (e.g., PTR hostname `msnbot-40-77-167-155.search.msn.com`).
• Subnet Stability: Subnet `40.77.167.155/24` shows moderate abuse density (27.94%), with 11 medium-risk neighbors and 76 low-risk IPs.

---

**3. Relationships**

• DNS Associations: Linked to `msnbot-40-77-167-155.search.msn.com` (Microsoft search bot infrastructure).
• Network Context: Same network as Microsoft’s Azure cloud infrastructure (MSFT).
• No External Threat Links: No correlated malicious campaigns, DNSBL listings, or TLS certificate anomalies.

---

**4. Neighborhood Analysis**

• Subnet Summary:

- Total IPs: 68 in `/24` subnet.

- Active IPs: 25 (42.7% utilization).

- Risk Distribution: 11 medium-risk IPs (16.2%), 76 low-risk IPs (98.5%).

• Notable Neighbors:

- `40.77.167.7` (riskScore 0, authorityScore 50).

- `40.77.167.0`/`40.77.167.2`/`40.77.167.3`/`40.77.167.6` (riskScore 25, authorityScore 60).

• Abuse Density: 27.94% (higher than average for Microsoft-owned subnets).

---

**5. Threat Context**

• No Direct Threat: IP itself is low-risk and associated with legitimate Microsoft infrastructure.
• Subnet Risk: Moderate abuse density suggests monitoring for lateral movement or compromised neighbors.
• DNS Validity: DNSSEC and CAA records are valid; no spoofing or misconfigurations detected.

---

**6. Recommendations**

1. Monitor Subnet Activity: Investigate medium-risk neighbors (e.g., `40.77.167.7`) for anomalous behavior.

2. Verify Network Segmentation: Ensure Azure workloads are isolated from public-facing assets.

3. Track DNS Behavior: Monitor `msnbot-40-77-167-155.search.msn.com` for unexpected query patterns.

4. Review Abuse Density: Correlate subnet abuse with internal logs to identify potential misconfigurations.
