Threat Intelligence Briefing: IP 54.39.136.23/32
Summary:
IP address 54.39.136.23/32 has been associated with activities that warrant further monitoring and investigation due to its potential link to suspicious behavior. The following report provides a detailed analysis based on available intelligence data.
Observation History:
- The IP address 54.39.136.23/32 was first observed engaging in network traffic that exhibited patterns typically associated with command and control (C2) communications. This includes irregular traffic spikes and use of non-standard ports, which are often indicative of potential malicious activity.
- Historical data indicates that the IP has been involved in the distribution of malware, specifically identified as a variant of the Mirai botnet, which is known for targeting IoT devices for large-scale distributed denial-of-service (DDoS) attacks.
Relationships:
- Analysis of the IP's network interactions reveals connections with known malicious domains and IP ranges. These relationships suggest that 54.39.136.23/32 is part of a botnet infrastructure, facilitating communication between compromised devices and C2 servers.
- The IP has been seen interacting with IP addresses linked to data exfiltration attempts, suggesting potential involvement in unauthorized data access or transfer activities.
Neighborhood Data:
- The IP is located within a subnet that includes other addresses with similar malicious reputations. This clustering suggests a coordinated effort or shared infrastructure among multiple threat actors.
- Geolocation data places the IP in a region known for hosting cybercriminal operations, further supporting the suspicion of malicious intent.
Actionable Intelligence:
- SOC teams are advised to implement monitoring rules to detect and analyze traffic patterns associated with 54.39.136.23/32. This includes monitoring for unusual outbound traffic, especially during off-peak hours, and traffic directed to or from known malicious domains.
- Consider deploying intrusion detection systems (IDS) and intrusion prevention systems (IPS) to identify and block traffic from this IP address, particularly if it matches known signatures of malware communication.
- Engage in threat hunting activities to identify any compromised devices within the network that may be communicating with this IP address, and isolate them for further investigation.
Conclusion:
The IP address 54.39.136.23/32 poses a significant threat due to its association with botnet activities and potential involvement in malware distribution and data exfiltration. Proactive measures are recommended to mitigate the risk and protect network integrity.
