The data is compiled to assist SOC analysts in understanding the potential risks associated with this IP address.
Observation History:
1. Geolocation and ASN:
- The IP address is geolocated to Russia.
- It is associated with AS45139, which is linked to the hosting provider Hetzner Online AG. Hetzner is known for its data centers and hosting services across Europe.
2. Domain Associations:
- The IP has been linked to several domains, some of which have been flagged for hosting suspicious content or engaging in malicious activities. These domains have been observed to serve as command and control (C2) servers for malware distributions.
3. Malware and Phishing Reports:
- Historical data indicates that the IP has been involved in hosting phishing sites and distributing malware payloads. This includes spear-phishing campaigns targeting specific industries.
4. Threat Intelligence Feeds:
- The IP address has been listed in multiple threat intelligence feeds as a known indicator of compromise (IoC). It has been associated with botnet activities and used in Distributed Denial of Service (DDoS) attacks.
Relationships:
1. Network Proximity:
- Neighboring IP addresses have shown similar patterns of behavior, suggesting a network of IPs under the same administrative control. This network has been used for launching cyberattacks and distributing malicious software.
2. Domain and Subdomain Activity:
- The IP address has been dynamically associated with multiple subdomains, often used to quickly change the infrastructure supporting phishing and malware activities. These domains frequently appear and disappear, complicating tracking efforts.
Neighborhood Data:
1. ASN Traffic Patterns:
- Analysis of AS45139 traffic patterns reveals a high volume of outbound connections, typical of C2 servers and botnet command centers. This pattern is consistent with the infrastructure used for orchestrating large-scale cyber campaigns.
2. Hosting Environment:
- The IP resides in a shared hosting environment, which complicates attribution but also indicates potential for co-location with other malicious entities. This environment is often exploited for its low cost and ease of setup for illicit activities.
Actionable Intelligence:
