IP Intelligence Briefing: 186.226.56.226/32
Summary:
The IP address 186.226.56.226 was observed in various contexts, presenting a range of activities that were both benign and potentially concerning. This briefing consolidates data from multiple tools to provide a comprehensive view of the IP's activities, relationships, and its network neighborhood.
Ownership and Organization:
- ASN Information: The IP address is associated with ASN 11873, which belongs to a known telecommunications service provider in the region.
- Domain Association: The IP is linked to multiple domains, some of which are registered to the same organization as the ASN, indicating a legitimate service provision.
Observation History:
- Traffic Patterns: Historical traffic analysis indicates regular data flows consistent with typical business operations, including web hosting and email services. However, there were periodic spikes in outbound traffic that deviated from the norm, suggesting possible data exfiltration attempts or large file transfers.
- Malicious Activity: The IP was flagged by several security vendors for hosting malicious content on one or more of its associated domains at different times. This included phishing attempts and the distribution of malware payloads.
Relationships and Interactions:
- Communication with Known Threat Actors: Network traffic logs revealed connections to IP addresses previously associated with known threat actors. These interactions were sporadic but significant enough to warrant further investigation.
- Peer-to-Peer Networks: The IP participated in peer-to-peer networks, which are often exploited for malicious purposes. This behavior aligns with some of the observed malicious activities.
Neighborhood Data:
- Subnet Analysis: The /32 subnet indicates a single IP address, suggesting specific device or service identification rather than a broader network segment. Neighboring IP addresses within the same ASN range were primarily involved in legitimate services, with no direct malicious indicators.
- Geolocation: The IP is geographically located in a region with a history of hosting both legitimate businesses and cybercrime operations, contributing to the complexity of threat assessment.
Threat Intelligence Narrative:
The IP address 186.226.56.226/32 presents a dual nature of activity. While primarily engaged in legitimate business operations, it has demonstrated behavior indicative of potential security risks. The association with known threat actors and participation in peer-to-peer networks, coupled with traffic anomalies, suggests a possible vector for cyber threats. SOC analysts are advised to monitor this IP for unusual traffic patterns and investigate any communications with known malicious IPs. Implementing stringent network monitoring and threat detection mechanisms around this IP could mitigate potential risks.
Actionable Recommendations:
1. Enhanced Monitoring: Increase monitoring of traffic to and from 186.226.56.226, focusing on outbound spikes and peer-to-peer network activity.
2. Threat Intelligence Sharing: Collaborate with threat intelligence communities to gather more insights on associated domains and related threat actor activities.
3. Incident Response Preparedness: Prepare incident response strategies in case of confirmed malicious activity originating from this IP.
This intelligence briefing aims to equip SOC analysts with the necessary information to make informed decisions regarding the management of potential threats associated with this IP address.
