Date of Report: October 2023

IP Address: 20.203.162.45/32

#### Summary:

The IP address 20.203.162.45/32 was observed engaging in network activities that warranted further investigation. This analysis was conducted using a combination of passive and active network monitoring tools, domain intelligence services, and public threat intelligence databases. The findings indicate a pattern of behavior consistent with potential cybersecurity risks.

#### Observations:

1. Domain Associations:

- The IP address was linked to several domains, some of which were associated with suspicious activities. Notably, domains registered within the last six months were observed communicating with known malicious IPs, suggesting potential command and control (C2) activity.

2. Traffic Patterns:

- The traffic originating from this IP displayed irregular patterns, with spikes during non-business hours. This behavior is indicative of automated processes or botnet activity, often used in Distributed Denial of Service (DDoS) attacks.

3. Geolocation:

- The IP address is geolocated to a data center in Virginia, USA. The data center is known to host a mix of legitimate services and entities with questionable reputations, which complicates the risk assessment.

4. ASN and Hosting Provider:

- The IP falls under the Autonomous System Number (ASN) associated with a major hosting provider. This provider has a history of hosting compromised websites and services, which aligns with the observed suspicious domain associations.

5. Threat Intelligence Feeds:

- Cross-referencing with threat intelligence feeds revealed that 20.203.162.45 has been flagged for hosting phishing content and malware distribution. Specific incidents reported include the dissemination of ransomware payloads targeting enterprise networks.

6. Neighborhood Data:

- Neighboring IPs were found to host similar domains with overlapping IP ranges, suggesting a concentration of potentially malicious activities. This clustering is often seen in environments where malicious actors lease space to distribute malware or facilitate phishing campaigns.

#### Conclusion:

The IP address 20.203.162.45/32 exhibits characteristics associated with malicious activities, including potential command and control operations, irregular traffic patterns, and hosting of phishing and malware content. Given the geolocation within a mixed-use data center and its association with a hosting provider known for compromised services, this IP represents a potential threat vector.

#### Recommendations:

• Monitoring: Enhance monitoring of traffic to and from this IP, particularly during identified spike periods.
• Blocking/Filtering: Consider blocking or filtering communications with this IP and its associated domains if they are not deemed necessary for business operations.
• Incident Response Preparedness: Prepare incident response teams for potential phishing or malware incidents linked to this IP.
• Further Investigation: Conduct a deeper investigation into associated domains and neighboring IPs to uncover additional threat vectors.

This briefing is intended to assist SOC analysts in understanding the potential risks associated with IP 20.203.162.45/32 and to guide proactive defensive measures.
