Threat Intelligence Briefing: IP 203.145.34.82/32
Summary:
The IP address 203.145.34.82/32, associated with the AS (Autonomous System) 13840, is primarily linked to an organization providing various digital services, including web hosting and cloud infrastructure. Historical data indicates a pattern of benign activity, primarily related to web hosting services. However, recent observations have highlighted several noteworthy activities that warrant closer monitoring.
Observation History:
- Past Activity: The IP has been consistently associated with legitimate web services, hosting multiple domain names related to e-commerce, media, and content delivery networks (CDNs). No significant security incidents or anomalies were recorded in the historical data.
- Recent Activity: Over the past month, there has been an increase in traffic volume and a higher frequency of connection attempts from a diverse set of external IP addresses, particularly those originating from regions with known cyber threat activities.
Relationships:
- Domain Associations: The IP address is linked to several domains, some of which have recently seen changes in DNS records, suggesting potential rebranding or restructuring within the hosted services.
- External Interactions: There have been notable interactions with IP addresses known for malicious activities, including those associated with phishing campaigns and botnet command and control (C2) servers. These interactions are limited but present enough to warrant attention.
Neighborhood Data:
- AS-Level Proximity: The IP is part of AS 13840, which hosts a mix of legitimate businesses and entities with varied reputations. The AS has been observed facilitating traffic for both reputable services and suspicious activities in the past.
- Subnet Analysis: Within the subnet, there are several other IPs with similar service functions but no direct evidence of malicious activity. The subnet's overall traffic patterns have remained stable, with no significant deviations observed.
Actionable Insights:
1. Monitoring Traffic: Increase monitoring of traffic originating from and directed to 203.145.34.82/32, focusing on connections to known malicious IPs.
2. DNS Changes: Track DNS changes for domains hosted by this IP to identify potential phishing or malicious redirection attempts.
3. External Connections: Investigate the nature of recent external connections, particularly those from high-risk regions, to determine if they are benign or indicative of a compromise.
4. Alert Configuration: Configure alerts for unusual traffic patterns or volume spikes, which may indicate unauthorized access or data exfiltration attempts.
Conclusion:
While 203.145.34.82/32 has historically been associated with legitimate services, the recent changes in traffic patterns and interactions with known threat actors suggest a potential risk that should be closely monitored. Implementing the recommended actions will help mitigate any potential threats and ensure the security of network operations.
