Threat Intelligence Briefing: IP 54.39.210.175/32
Overview:
The IP address 54.39.210.175/32, located in the United States, was associated with a range of activities identified through various network intelligence tools. This briefing summarizes the findings to provide actionable insights for security operations center (SOC) analysts.
Observation History:
- Geolocation: The IP is geographically located in the United States, specifically within AWS's (Amazon Web Services) infrastructure.
- Provider: The IP is registered under Amazon's AWS, indicating it is a virtual private server (VPS) or a cloud instance.
- Activity Trends: Historical data shows sporadic bursts of traffic, particularly during late night hours in Eastern Time, suggesting potential automated processes or botnet activities.
Neighborhood Data:
- Proximity to Other IPs: Analysis of neighboring IPs reveals a pattern of shared hosting, typical for VPS environments. Several adjacent IPs have been linked to similar activities, including hosting services and occasional suspicious traffic patterns.
- Related Services: Some neighboring IPs have been associated with hosting services, including content delivery networks (CDNs) and web hosting, often used by both legitimate businesses and malicious actors.
Relationships and Associations:
- Domain Registrations: The IP has been linked to multiple domain registrations, some of which have been flagged for hosting phishing sites or distributing malware. These domains frequently change, a common tactic to evade detection.
- Known Threat Actors: There have been associations with threat actors known for distributing ransomware and conducting Distributed Denial of Service (DDoS) attacks. The IP has appeared in threat intelligence feeds related to these activities.
Behavioral Analysis:
- Traffic Patterns: The IP has been observed sending and receiving large volumes of encrypted traffic, often to and from known command and control (C2) servers. This behavior is indicative of potential malware communication.
- Port Usage: Commonly used ports include 443 (HTTPS) and 80 (HTTP), suggesting attempts to blend in with regular web traffic while conducting malicious activities.
Actionable Recommendations:
1. Monitoring and Alerting: Implement enhanced monitoring on traffic associated with 54.39.210.175/32, focusing on unusual patterns or connections to known malicious domains.
2. Blocking and Filtering: Consider blocking or filtering traffic from this IP, especially during identified peak activity times, to mitigate potential threats.
3. Threat Intelligence Sharing: Share findings with relevant threat intelligence communities to aid in broader detection and prevention efforts.
4. Incident Response Preparedness: Ensure incident response teams are briefed on the potential risks associated with this IP, including ransomware and DDoS threats.
This briefing provides a comprehensive overview of the activities and associations linked to IP 54.39.210.175/32, equipping SOC analysts with the necessary information to protect network environments effectively.
