Summary:
The IP address 54.38.147.92/32, assigned to Amazon Web Services (AWS) in the US West (Oregon) region, was observed engaging in activities that warranted further investigation. The analysis leveraged multiple data sources, including IP reputation databases, network traffic analysis, and historical incident reports. This briefing consolidates these findings into a coherent narrative for SOC analysts.
Key Observations:
1. Ownership and Infrastructure:
- The IP address is owned by Amazon Web Services, specifically within the US West (Oregon) region. This is a common hosting environment for numerous legitimate services, but it also presents opportunities for misconfiguration or exploitation by malicious actors.
2. Activity Patterns:
- Network traffic analysis indicated sporadic but significant spikes in outbound traffic. These patterns are often indicative of data exfiltration attempts or communication with command-and-control (C2) servers.
- Historical data revealed multiple connections to known malicious domains, suggesting potential involvement in botnet activities or malware distribution.
3. Reputation and Blacklisting:
- The IP has been flagged by several threat intelligence platforms for associations with phishing campaigns and malware distribution. It appears on multiple blocklists, reinforcing its suspicious nature.
4. Neighborhood and Peer Connections:
- Analysis of neighboring IP addresses showed a mix of legitimate and questionable entities. Several adjacent IPs have been implicated in similar malicious activities, suggesting a potential network of compromised or maliciously configured resources.
- Peer-to-peer connections from this IP were observed with known bad-actor IPs, further supporting its involvement in malicious activities.
Actionable Intelligence:
- Monitoring and Alerts:
- Establish enhanced monitoring for traffic originating from or directed to 54.38.147.92/32. Utilize intrusion detection systems (IDS) to identify and alert on known malicious patterns.
- Blocking and Filtering:
- Consider adding this IP to organizational blocklists to prevent potential communication with malicious endpoints. Review and update firewall rules to restrict outbound traffic to known malicious domains.
- Incident Response:
- Prepare for potential incident response scenarios involving this IP. Ensure that teams are aware of the threat landscape and have procedures in place to quickly isolate and analyze any related incidents.
- Continuous Analysis:
- Continuously update threat intelligence feeds to track any changes in the activity or reputation of this IP. Regularly review logs and network traffic to detect emerging threats.
Conclusion:
The IP address 54.38.147.92/32, despite being hosted on a reputable cloud platform, has demonstrated behavior consistent with malicious activities. SOC teams should prioritize monitoring, blocking, and incident response preparations to mitigate potential threats associated with this IP. Continuous vigilance and adaptation to new intelligence are recommended to effectively counter any emerging risks.
