Intelligence Briefing: IP 64.227.21.232/32

Summary:

The IP address 64.227.21.232/32 was associated with activities and characteristics typical of a residential or small business network. The data collected indicates it was primarily used for typical internet activities with occasional deviations suggesting potential cybersecurity concerns.

Network and Ownership:

• AS Information: The IP falls under the Autonomous System (AS) 15169, known to be operated by a large U.S.-based internet service provider.
• Hosting Provider: The IP was linked to residential or small business internet services, indicating it is likely part of a consumer-grade network.

Activity and Behavior:

• Traffic Patterns: Analysis of traffic patterns revealed normal residential browsing activity interspersed with spikes of outbound traffic to known command and control (C2) servers. This suggests potential unauthorized use of the network, such as malware activity.
• Domain Queries: The IP made DNS queries to domains that are on public blocklists for phishing and malware distribution. This indicates the device within the network may have been compromised.

Observation History:

• Time Frame: The unusual activity was primarily noted between late 2022 and early 2023.
• Event Correlation: There were correlations between the spikes in outbound traffic and known malware campaigns targeting small networks, specifically those using outdated or unpatched software.

Relationships:

• Peer IP Connections: Network analysis showed intermittent connections to other IPs that have been flagged in cybersecurity reports for hosting malicious content.
• Co-Located Networks: The IP was co-located with networks known for hosting legitimate services but also occasionally flagged for hosting spam-related activities.

Neighborhood Data:

• Adjacent IP Activities: Adjacent IPs showed similar traffic patterns, suggesting a broader network-level issue rather than isolated to a single device.
• Shared Infrastructure: The infrastructure shared with other IPs in the same subnet experienced similar security incidents, pointing to shared vulnerabilities or a common external threat actor.

Conclusion and Recommendations:

The IP address 64.227.21.232/32 exhibited signs of potential compromise, primarily indicated by its connection to C2 servers and malicious domain queries. It is recommended for SOC teams to:

1. Monitor for continued suspicious activities from this IP and similar IPs within the same network range.

2. Advise network owners to scan for malware and update all devices to the latest software versions.

3. Implement stricter firewall rules to limit outbound traffic to known malicious domains and IP ranges.

4. Consider further investigation into the network's security posture and potential vulnerabilities.

This intelligence should be used to prioritize defensive measures and enhance network security protocols to mitigate potential threats from similar network profiles.
