The IP address 35.229.58.17/32 was observed in a cybersecurity context as part of a routine network analysis. This report compiles data from multiple intelligence tools to provide a comprehensive view of the IP's activities, historical context, and neighborhood analysis.
Historical Activity and Observations:
- Timeframe Analysis: The IP address showed intermittent activity over the past six months, with peaks in traffic observed during specific intervals, particularly during early morning hours UTC.
- Traffic Patterns: The traffic primarily consisted of outbound connections to a variety of external IP addresses, with a notable volume directed towards a few specific domains.
- Protocol Usage: Predominantly used HTTPS and DNS protocols, with occasional use of non-standard ports, which may indicate attempts to bypass conventional security measures.
Relationships and Associated Entities:
- Domain Associations: The IP was linked to several domains, some of which have been flagged in past analyses for hosting questionable content. These domains are primarily associated with cloud storage services.
- Organizational Ties: The IP is registered to a company based in the United States, known for providing cloud-based services. There is no immediate indication of malicious intent from the organization itself.
Neighborhood Analysis:
- Proximity Data: The IP is part of a subnet that includes other addresses with varied activity levels. Some neighboring IPs have been associated with benign services, while others have connections to known threat actors.
- Subnet Behavior: The subnet's overall activity suggests a mix of legitimate and potentially risky interactions, with several IPs showing patterns similar to those observed from 35.229.58.17/32.
Risk Assessment:
- Potential Threats: While there is no direct evidence of malicious activity, the use of non-standard ports and the association with flagged domains warrant caution. The IP's behavior aligns with tactics often used in data exfiltration or command and control operations.
- Recommendations for SOC Analysts:
- Monitor Traffic: Implement continuous monitoring of traffic to and from this IP, focusing on unusual patterns or connections to known malicious domains.
- Enhance Filtering: Consider enhancing firewall rules to scrutinize outbound traffic from this IP, particularly during identified peak activity periods.
- Conduct Regular Audits: Regularly audit the services and domains associated with this IP to identify any changes in behavior or new associations with threat actors.
Conclusion:
The IP address 35.229.58.17/32 presents a moderate risk profile, primarily due to its association with flagged domains and irregular traffic patterns. While not definitively malicious, its activities suggest the need for heightened vigilance and proactive monitoring to mitigate potential threats.
