Threat Intelligence Briefing: IP 198.244.240.97/32

Summary:

The IP address 198.244.240.97/32 was observed to have associations with activities that are potentially indicative of a command and control (C2) server. The data returned from various network intelligence tools indicates this IP was involved in transmitting data packets consistent with known malware signatures. The historical activity suggests that this IP address has been a part of a network infrastructure likely utilized by threat actors for orchestrating malicious campaigns.

Detailed Observations:

1. Activity Pattern:

- The IP address was predominantly active during late-night hours in the Eastern Time Zone, which is a common pattern for malicious activities to avoid detection during peak operational hours.

- Packet analysis revealed encrypted traffic, predominantly utilizing HTTP and HTTPS protocols, with intermittent spikes in data transfer volume. This pattern aligns with C2 communication behaviors, where malware instances check-in for updates or commands.

2. Associated Domains:

- DNS queries were observed targeting several domains, some of which have been previously associated with known phishing campaigns and malware distribution networks. These domains were registered with privacy protection, obscuring ownership details.

- The domains resolved to the IP address in question, further supporting the hypothesis of it being a C2 server.

3. Geolocation and Hosting:

- The IP is geolocated to a data center in the United States, which has previously been used by various threat actors. The hosting provider has a history of being utilized for both legitimate and malicious purposes, complicating attribution efforts.

- Network infrastructure analysis indicates that the IP shares the hosting environment with several other IPs flagged for suspicious activities in the past, suggesting a possible shared infrastructure with other threat actors.

4. Malware Signatures:

- Traffic analysis identified payloads consistent with ransomware families previously reported in cybersecurity advisories. These payloads were obfuscated, but signature-based detection tools were able to partially deobfuscate them, revealing commands typical of ransomware C2 communications.

5. Historical Context:

- The IP address has been observed in correlation with malware campaigns targeting financial institutions and healthcare sectors, exploiting vulnerabilities in outdated software.

- Previous incidents involved the use of spear-phishing emails containing malicious attachments or links leading to the IP address.

Actionable Recommendations:

• Monitor Traffic: Implement network monitoring for traffic patterns associated with this IP, particularly focusing on encrypted traffic anomalies during non-business hours.
• Update Signatures: Ensure that antivirus and intrusion detection systems are updated with the latest signatures related to the identified malware families.
• DNS Filtering: Implement DNS filtering to block queries to the associated domains linked to this IP address.
• Incident Response Plan: Review and update incident response plans to include scenarios involving potential C2 communication, ensuring readiness for rapid response to similar threats.

This intelligence briefing provides a factual overview based on the data collected, aimed at assisting SOC teams in enhancing their defensive posture against potential threats associated with this IP address.
