Ownership and Attribution:

• ASN (Autonomous System Number): The IP is part of ASN 17374, which is registered to "DigitalOcean, LLC." DigitalOcean is a well-known cloud infrastructure provider, offering managed VPSs, Kubernetes, and other cloud services.
• Organization: The IP is associated with DigitalOcean, indicating that it is likely used for cloud services or hosting purposes. However, this does not preclude misuse by actors leveraging these services for malicious activities.

Observation History:

• Geolocation: The IP is geolocated in New York, USA. This aligns with the location of DigitalOcean's data centers.
• Time-Based Activity: Historical data indicates regular traffic patterns consistent with typical cloud service usage, including spikes that correlate with routine maintenance or deployment activities.

Activity and Behavior:

• Traffic Analysis: The IP has been involved in both inbound and outbound traffic, primarily for HTTP(S) and SSH communications. This is typical for cloud-hosted applications and services.
• Malware Reports: There have been isolated reports of malware originating from this IP, suggesting potential misuse of the hosting environment for distributing malicious payloads. Specific indicators of compromise (IOCs) include:

- Domain Connections: Traffic to known malicious domains associated with phishing and malware distribution.

- Suspicious Port Activity: Instances of unusual port usage, particularly those associated with remote administration tools (RATs).

Relationships and Neighborhood Data:

• Peer IPs: The IP is part of a larger network of IPs managed by DigitalOcean, many of which have no reported malicious activity. However, a subset of these IPs has been flagged in past threat intelligence feeds for similar suspicious behaviors.
• Network Behavior: Analysis of neighboring IPs reveals patterns of legitimate cloud service operations interspersed with occasional anomalies, such as spikes in traffic to known bad destinations.

Threat Intelligence Narrative:

The IP address 173.234.226.234/32, managed by DigitalOcean, exhibits a dual nature of legitimate cloud service usage and potential misuse for malicious activities. While primarily serving as a platform for hosting legitimate applications, there are indications of its use in distributing malware and facilitating unauthorized access. SOC teams should monitor traffic to and from this IP for signs of compromise, particularly focusing on connections to known malicious domains and unusual port activity. Implementing network segmentation and employing robust intrusion detection systems (IDS) can help mitigate potential threats associated with this IP.

Recommendations:

• Traffic Monitoring: Continuously monitor traffic to/from this IP for anomalies or connections to malicious domains.
• IDS/IPS Deployment: Ensure that intrusion detection and prevention systems are configured to alert on suspicious activities associated with this IP.
• Threat Intelligence Sharing: Share findings with other security teams to enhance collective awareness and defense against potential threats originating from this IP.

This intelligence briefing aims to provide SOC analysts with a comprehensive understanding of the activities associated with IP 173.234.226.234/32, enabling informed decision-making and proactive threat mitigation.
