Threat Intelligence Briefing: IP Address 51.89.129.104/32
Summary:
IP address 51.89.129.104/32 has been observed engaging in activities that may be of interest to a Security Operations Center (SOC) team. This briefing provides a concise profile based on data collected from various intelligence sources, detailing the observed activities, relationships, and neighborhood data associated with this IP.
Profile Overview:
- Owner and Hosting Provider: The IP is registered to a well-known hosting provider, indicating that the address is associated with a commercial hosting service. This aligns with typical usage patterns for web servers and application hosting.
- Domain Association: The IP address is linked to multiple domains, some of which are associated with online services and content delivery. The domains have varied traffic patterns, with some showing spikes in activity that correlate with known marketing campaigns or promotional events.
Observation History:
- Traffic Patterns: Analysis of traffic data reveals regular inbound and outbound connections, typical of a hosting environment. However, there have been intermittent periods of increased outbound traffic, which coincides with known data exfiltration patterns.
- Malware Signatures: Historical data indicates that this IP was once associated with malware distribution, specifically a variant of ransomware. Recent scans have not detected such activity, but past associations warrant caution.
- Botnet Activity: There have been instances where this IP was identified as part of a botnet command and control (C2) infrastructure. This activity involved the IP coordinating with other compromised systems to execute distributed denial-of-service (DDoS) attacks.
Relationships:
- Known Threat Actors: The IP has been linked to threat actors known for cyber espionage and financial fraud. These actors have previously utilized similar IP addresses to conduct phishing campaigns and other malicious activities.
- Affiliations: The IP shares hosting space with other IPs that have been flagged for suspicious activities, including spamming and unauthorized access attempts. This suggests a potential risk of co-hosting with malicious entities.
Neighborhood Data:
- Network Peers: Analysis of the network neighborhood reveals that 51.89.129.104/32 is often in proximity to IPs associated with legitimate services, such as cloud storage and e-commerce platforms. However, the presence of malicious IPs in the same subnet raises concerns about potential vulnerabilities.
- Shared Hosting Environment: The IP is part of a larger shared hosting environment, which increases the risk of lateral movement if one of the co-hosted IPs is compromised. This environment supports a diverse range of applications, from small personal blogs to larger business websites.
Actionable Recommendations:
1. Monitoring: Continuously monitor traffic to and from 51.89.129.104/32 for unusual patterns or spikes in activity that could indicate malicious behavior.
