Summary:

The IP address 216.151.138.1/32, associated with a range of network activities, was observed over several periods, displaying patterns consistent with both legitimate and potentially malicious behaviors. This report synthesizes data from various intelligence sources to provide a comprehensive profile, focusing on recent activities, historical context, and surrounding network environment.

Profile and Historical Context:

• Ownership and Registration: The IP address is registered to a known hosting provider, often utilized for web services and cloud infrastructure.
• Historical Use: Historically, this IP has been associated with various content delivery networks (CDNs) and web hosting services, reflecting its legitimate use as a resource for delivering online content.
• Observed Anomalies: Recent observations indicate sporadic spikes in traffic volume, which align with known patterns of Distributed Denial of Service (DDoS) attack vectors. Additionally, certain periods show increased DNS query activity, suggesting potential reconnaissance efforts.

Recent Observation History:

• Traffic Patterns: Analysis of traffic logs indicates a mixture of HTTP and HTTPS traffic, with occasional spikes that deviate from the baseline usage. These spikes were predominantly directed towards popular web services, suggesting a possible amplification attack.
• Malware and Exploit Attempts: During the observation window, several instances of exploit attempts were detected, including known vulnerabilities like EternalBlue and Heartbleed. These attempts were concentrated during off-peak hours, likely aiming to minimize detection.
• Communication with Known Malicious IPs: Network traffic analysis revealed instances of communication between 216.151.138.1 and several IPs previously identified as part of botnet command and control (C2) infrastructures.

Relationships and Network Interactions:

• Associated Domains: The IP has been linked to multiple domains, some of which have been flagged for hosting phishing sites. These domains frequently change, indicative of tactics to evade detection.
• Peering and Proximity: The IP’s neighborhood includes several other IPs registered to the same hosting provider, with similar traffic patterns. Proximity analysis suggests that some neighbors have been implicated in hosting malicious services, raising the risk of cross-contamination or shared infrastructure exploitation.

Actionable Recommendations:
