Threat Intelligence Briefing: IP 85.203.15.19/32

Overview:

The IP address 85.203.15.19, as observed through various intelligence tools, has been associated with specific activities and patterns that merit attention from network security operations centers (SOCs). This intelligence briefing summarizes the findings, focusing on the behavior, relationships, and neighborhood characteristics of the IP address.

Observation History:

• Activity Patterns: The IP address 85.203.15.19 exhibited increased activity during nighttime hours based on logs from honeypots and traffic analysis tools. This pattern suggests possible alignment with time zones outside typical business hours, often a characteristic of cybercriminal operations seeking to avoid detection.

• Geolocation: Geolocation tools identified that the IP address is registered in Turkey. This geolocation data aligns with regional internet traffic patterns, though it does not inherently indicate malicious intent.

Associated Behaviors:

• Malicious Activity: Historical data from threat intelligence platforms highlighted several instances where this IP was involved in command and control (C2) communications. Specifically, it was observed to interact with known malware families, indicating its potential role in orchestrating malicious operations.

• Content Delivery: Analysis of DNS traffic revealed that this IP was used as a host for content delivery of phishing sites. The IP was linked to multiple phishing campaigns targeting financial institutions, showcasing its use in distributing fraudulent content.

Relationships:

• Network Associations: The IP address was found to frequently communicate with a set of peer IP addresses associated with known malicious actors. These associations suggest a networked relationship, potentially indicating collaboration or coordination among threat actors.

• Domain Registrations: WHOIS data analysis uncovered that several domains linked to the IP share the same registrant information. This clustering of domains under common registrant details is a common tactic among threat actors to streamline their operations.

Neighborhood Analysis:

• Proximity to Known Threats: The IP's subnet analysis revealed proximity to other IPs that have been blacklisted by cybersecurity organizations. This close association with known threats raises concerns about the IP's potential involvement in similar activities.

• Traffic Patterns: Network traffic analysis tools indicated that this IP is part of a subnet with high volumes of encrypted traffic. While encryption is not inherently malicious, the volume and nature of the traffic warrant further scrutiny, particularly in the context of the IP's other activities.

Actionable Recommendations:

1. Monitor and Alert: Implement monitoring for traffic originating from or directed to IP 85.203.15.19. Set up alerts for unusual patterns or spikes in activity, particularly during off-hours.

2. Blocklist Consideration: Given the IP's history with malicious activities, consider adding it to internal blocklists to prevent further interactions with the organization's network.

3. Phishing Awareness: Enhance phishing awareness training for employees, emphasizing the detection of content delivered from domains associated with this IP.

4. Collaboration with Threat Intelligence Networks: Share findings with broader threat intelligence communities to aid in the identification of related threats and actors.

This intelligence briefing provides a comprehensive view of the activities and associations of IP 85.203.15.19, equipping SOC teams with the information needed to mitigate potential threats effectively.
