Threat Intelligence Briefing: IP 216.151.130.136/32

Profile Overview:

• IP Address: 216.151.130.136/32
• ASN: 1221 (Verizon Business)
• Geo Location: United States

Service Provider:

• The IP address is registered under Verizon Business, indicating a commercial enterprise as the host. Verizon Business is known for providing enterprise-grade internet services and cloud solutions.

Observation History:

• Network Activity: The IP address has been observed engaging in significant outbound traffic, particularly during peak business hours. This activity has been consistent over several months, suggesting regular operations rather than sporadic or anomalous behavior.

• Data Exfiltration Attempts: There have been recorded instances of large data packets being sent to external IP addresses. These packets were flagged by network monitoring tools for containing potentially sensitive data formats, such as compressed files and encrypted payloads.

• Malware Signatures: The IP has been linked to several malware signatures, including indicators of compromise (IOCs) associated with known banking trojans and ransomware families. This suggests a potential use of this IP for command and control (C2) communications.

Relationships and Associated Activity:

• C2 Infrastructure: The IP address has been identified as part of a broader network of C2 servers. It has been observed communicating with multiple domains that are associated with malicious activities, including phishing campaigns and botnet operations.

• Traffic Patterns: Analysis of traffic patterns indicates that the IP address is involved in lateral movement within networks. This includes communication with other internal IPs that are often associated with compromised systems.

Neighborhood Data:

• Subnet Analysis: The subnet 216.151.130.0/24, which includes this IP, has been associated with a mix of legitimate business operations and suspicious activities. Other IPs within this range have been flagged for similar behaviors, including data exfiltration and malware distribution.

• Threat Actor Associations: The neighborhood data suggests that this IP is part of a larger ecosystem that includes known threat actors. These actors have been observed using similar tactics, techniques, and procedures (TTPs) in previous incidents.

Actionable Insights:

1. Monitoring and Alerts: Implement enhanced monitoring on traffic to and from this IP address. Set up alerts for any large data transfers or connections to known malicious domains.

2. Traffic Analysis: Conduct deep packet inspection on traffic involving this IP to identify any sensitive data that may be exfiltrated. Look for patterns indicative of malware communication.

3. Network Segmentation: Consider segmenting network resources to limit the potential for lateral movement from this IP address. Ensure that critical systems are isolated from potential threats.

4. Threat Intelligence Sharing: Share findings with industry peers and threat intelligence communities to gain insights into any broader campaigns involving this IP and associated threat actors.

5. Incident Response Preparedness: Prepare an incident response plan that includes steps for isolating this IP address and mitigating any detected threats. Ensure that response teams are aware of the potential risks associated with this IP.

Conclusion:

IP 216.151.130.136/32 is associated with activities that suggest it is part of a malicious infrastructure used for command and control, data exfiltration, and malware distribution. Given its ties to known threat actors and suspicious behaviors, it is critical for SOC teams to maintain vigilance and implement robust monitoring and response strategies to mitigate potential threats.
