Overview:

The IP address 43.157.226.112/32 is associated with a range of network activities that merit attention for security operations center (SOC) teams. This IP address is geolocated in the United States, specifically within a data center environment. The network footprint suggests a combination of legitimate services alongside potentially suspicious activity that warrants further analysis.

Observation History:

1. Service Utilization:

- The IP address hosts a variety of services, including web applications, email servers, and cloud storage solutions. These services are indicative of legitimate enterprise operations.

- Historical data shows regular traffic patterns during standard business hours, consistent with typical business operations.

2. Suspicious Activity:

- There have been intermittent spikes in outbound traffic, particularly to regions known for cyber threat actors. These spikes are atypical for the observed service profile and suggest potential data exfiltration attempts.

- DNS queries from the IP address have been observed targeting domains with a history of malicious activity. This includes domains known for command and control (C2) operations.

Relationships and Interactions:

1. Known Associations:

- The IP address has been observed communicating with other IPs within the same data center, suggesting shared infrastructure usage.

- There is a documented relationship with several IPs that have been flagged for hosting phishing campaigns, indicating possible misuse of shared resources.

2. Network Neighbors:

- Analysis of the network neighborhood reveals that the IP address shares its data center with a mix of legitimate businesses and entities with questionable reputations. This co-location increases the risk of collateral compromise.

- Traffic analysis shows frequent interactions with IPs associated with known threat actors, raising concerns about potential compromise or misuse.

Threat Indicators:

• Indicators of Compromise (IoCs):

- Unusual outbound traffic patterns, especially towards regions with high cybercrime activity.

- DNS queries to known malicious domains.

- Communication with IPs involved in phishing and other cybercrime activities.

Actionable Recommendations:

1. Enhanced Monitoring:

- Increase monitoring of outbound traffic from the IP address, focusing on unusual spikes or patterns.

- Implement DNS filtering to block queries to known malicious domains.

2. Incident Response Preparation:

- Prepare for potential incident response activities, including containment and eradication strategies, should further analysis confirm malicious activity.

- Review and update firewall rules to restrict communication with IPs associated with threat actors.

3. Collaboration with Data Center Provider:

- Engage with the data center provider to investigate shared infrastructure risks and implement additional security measures if necessary.

4. Threat Intelligence Sharing:

- Share findings with relevant threat intelligence communities to aid in broader detection and prevention efforts.
