Threat Intelligence Briefing: IP 51.89.129.102/32

Summary:

The IP address 51.89.129.102 was observed to engage in activities consistent with a command and control (C2) server associated with a known malware family. The network traffic originating from this IP indicated attempts to communicate with multiple compromised endpoints across various geographical locations.

Observation History:

• Recent Activity: The IP was noted to initiate outbound connections to compromised endpoints using a range of ports, primarily targeting ports 80 and 443. These connections were consistent with C2 traffic patterns.
• Payload Characteristics: Encrypted payloads were detected, which upon decryption using known malware signatures, revealed commands intended to exfiltrate data and gather system information.
• Geolocation: The IP is located in a data center in Europe, specifically within a hosting provider known for mixed-use environments, including both legitimate enterprises and entities with dubious reputations.

Relationships:

• Associated Domains: The IP was linked to several domains that have been previously flagged for hosting malicious content. DNS resolution for these domains showed frequent changes, indicative of domain generation algorithm (DGA) usage.
• Malware Family: The observed traffic and payload characteristics align with the "Emotet" malware family, a prevalent banking trojan known for its modular architecture and ability to download additional payloads.
• Compromised Endpoints: Analysis of traffic logs revealed interactions with endpoints across North America, Europe, and Asia, suggesting a wide-reaching impact.

Neighborhood Data:

• Neighboring IPs: The immediate subnet hosted a variety of IPs, some associated with legitimate services, while others were linked to suspicious activities, including known phishing operations and spamming.
• Hosting Provider Reputation: The data center hosting this IP has a mixed reputation, with several instances of hosting IPs associated with botnets and fraudulent activities.

Actionable Intelligence:

• SOC Monitoring: Enhance monitoring of outbound traffic to the specified IP and associated domains. Implement network segmentation to isolate potentially compromised systems.
• Indicators of Compromise (IOCs): Utilize the observed domains and encrypted payload signatures to update threat detection systems.
• Endpoint Protection: Deploy endpoint detection and response (EDR) solutions to identify and mitigate potential Emotet infections.
• Incident Response: Prepare for potential incident response scenarios by reviewing and updating incident response plans to address threats associated with Emotet and similar malware families.

This intelligence briefing provides a comprehensive overview of the activities and characteristics associated with IP 51.89.129.102, enabling SOC analysts to take informed, proactive measures against potential threats.
