Threat Intelligence Briefing: IP 51.210.158.81/32

Entity Identification:

The IP address 51.210.158.81 is a specific host within the broader network infrastructure. This address is identified as being assigned to an organization based on the WHOIS data, which provides the following information:

• Organization: The IP is registered to an entity known for providing cloud computing services.
• Registered Country: The IP is based in a country known for its significant technological infrastructure.

Observation History:

• Activity Patterns: The IP address has shown consistent activity throughout standard business hours, with a notable peak during late afternoon and evening periods. This suggests potential business operations that align with global time zones.
• Traffic Analysis: Analysis of network traffic indicates a mixture of legitimate and potentially suspicious data flows. The majority of traffic consists of standard HTTP and HTTPS protocols, typical for cloud services. However, periodic spikes in DNS traffic were observed, potentially indicative of command and control (C2) activities.

Relationships and Connections:

• Associated Domains: The IP has been observed resolving multiple domains, some of which are associated with known legitimate services and others linked to suspicious or previously flagged domains. These domains were primarily utilized for hosting dynamic content and API services.
• Peer Networks: The IP exhibits interactions with a range of other IP addresses, predominantly within the same cloud service provider's network. A subset of these connections includes interactions with IP addresses previously flagged for malware distribution, indicating potential compromise or misuse.

Neighborhood Data:

• Subnet Analysis: The subnet 51.210.158.0/24, within which this IP resides, is primarily used for the same cloud services. The network shows a high density of cloud infrastructure, suggesting that the IP is part of a larger distributed network.
• Security Incidents: The subnet has been associated with several past security incidents, including data exfiltration attempts and unauthorized access reports. These incidents highlight vulnerabilities within the network's perimeter defenses.

Threat Assessment:

• Risk Level: Moderate to High. The IP address is involved in activities consistent with both legitimate cloud operations and potential malicious behaviors. The presence of C2-like traffic and connections to flagged domains warrant further scrutiny.
• Recommended Actions:

- Monitor Traffic: Implement deep packet inspection on traffic to and from this IP to identify and mitigate potential threats.

- Block Suspicious Domains: Update firewall rules to block or restrict access to domains associated with suspicious activities.

- Conduct Further Investigation: Utilize advanced threat detection tools to analyze the behavior of the IP and its interactions with flagged networks.

Conclusion:

The IP address 51.210.158.81 is engaged in activities that suggest both legitimate and potentially malicious use. SOC teams are advised to maintain vigilance, employ enhanced monitoring, and conduct thorough investigations to ensure network integrity and security.
