Threat Intelligence Briefing: IP 162.12.208.107/32

Summary:

The IP address 162.12.208.107/32 was observed to be associated with network activities potentially indicative of a command and control (C2) server. This IP was identified as part of a larger campaign targeting enterprise networks, utilizing spear-phishing emails to deliver a payload that established a reverse shell communication with this server.

Observation History:

• Initial Detection: The IP 162.12.208.107 was first identified in February 2023 during an incident response operation where anomalous outbound traffic patterns were observed.
• Activity Patterns: Subsequent observations revealed consistent periods of activity primarily during business hours, aligning with the time zones of North American and European regions. This pattern suggested a strategic engagement with targeted victims.

Relationships:

• Associated Domains: DNS resolution records indicated multiple domains frequently resolving to this IP. These domains were primarily short-lived, suggesting the use of fast flux techniques to evade detection and block lists.
• Related IPs: Network traffic analysis revealed a series of other IPs within the same /24 subnet (162.12.208.0/24) showing similar behavior. These IPs were often rotated to maintain persistence within targeted networks.

Neighborhood Data:

• Subnet Analysis: The /24 subnet containing this IP address was found to host a mix of legitimate services and questionable traffic patterns, complicating attribution. However, the majority of suspicious activity was confined to a specific range of addresses.
• Geolocation: Geolocation data indicated that the IP is physically located in a data center in the United States. The data center is known for hosting a variety of clients, including some with questionable reputations.

Threat Indicators:

• Malware Signatures: The payloads delivered via spear-phishing campaigns were identified as variants of a known banking trojan, which has been associated with financial fraud and data exfiltration.
• Communication Protocols: The reverse shells utilized non-standard ports and encrypted communication channels, indicating an attempt to avoid standard network security measures.

Actionable Recommendations:

1. Network Monitoring: Implement enhanced monitoring for DNS queries to the domains associated with this IP, and flag any attempts to establish outbound connections to known suspicious ports.

2. Email Filtering: Strengthen email filtering rules to detect and block spear-phishing attempts, particularly those containing links or attachments related to identified malicious domains.

3. Endpoint Protection: Ensure all endpoints have updated antivirus and anti-malware solutions capable of detecting and mitigating the identified banking trojan variants.

4. Incident Response Plan: Update incident response protocols to include procedures for isolating and investigating suspicious activity linked to this IP address and its related domains.

This intelligence briefing provides a comprehensive overview of the threat landscape associated with IP 162.12.208.107/32, enabling SOC teams to take informed, proactive measures to protect their networks.
