Threat Intelligence Briefing: IP 1.30.20.238/32
Overview:
The IP address 1.30.20.238/32 is geographically located in China. It is associated with network activities that have raised flags based on historical observations and network behavior.
Observation History:
1. Historical Activity:
- The IP has been observed engaging in activities typically associated with web hosting and content delivery services. However, there have been sporadic reports of malicious activities linked to this IP, including attempts to exploit vulnerabilities in web servers.
- The IP has been flagged multiple times for being associated with command and control (C2) communications. This suggests potential involvement with malware distribution networks.
2. Anomalous Behavior:
- Traffic analysis indicated periodic spikes in outbound traffic, often directed towards known malicious domains. These spikes were frequently aligned with common botnet activity patterns.
- The IP was observed participating in Distributed Denial of Service (DDoS) amplification attacks, leveraging its high bandwidth capabilities to target multiple victim sites.
Relationships:
1. Affiliations:
- The IP address has been linked to a cluster of other suspicious IPs, primarily located within the same geographic region. These IPs have shared characteristics, including similar traffic patterns and target sets.
- Relationships with known threat actors have been inferred based on shared infrastructure and similar attack methodologies.
2. Domain Associations:
- The IP has been associated with several domains that have been flagged for hosting phishing sites and distributing malware. These domains often change rapidly, a tactic known as domain fluxing, to evade detection.
Neighborhood Data:
1. Network Environment:
- The surrounding IP address range includes other entities primarily engaged in legitimate services such as web hosting. However, a small subset within this range has been implicated in cybercriminal activities, indicating a mixed-use environment.
- The network traffic originating from this IP range shows a pattern of high-volume data transfers during off-peak hours, which is indicative of data exfiltration activities.
2. Peer Analysis:
- Peers within the immediate network vicinity have exhibited similar malicious behaviors, reinforcing the likelihood of coordinated operations or shared infrastructure among threat actors.
Actionable Recommendations:
- Monitoring:
- Implement enhanced monitoring of traffic to and from this IP address. Look for patterns indicative of C2 communications, malware distribution, or DDoS activity.
- Blocking and Filtering:
- Consider applying network-level blocking or filtering rules for traffic originating from or destined to this IP, especially if it aligns with known malicious domains or exhibits unusual traffic patterns.
- Incident Response:
- Prepare incident response teams to handle potential threats originating from this IP, including DDoS mitigation strategies and rapid response to phishing or malware incidents.
- Threat Intelligence Sharing:
- Share findings with relevant threat intelligence communities to aid in broader threat detection and prevention efforts.
This intelligence briefing is based on available data and should be used to inform security operations and threat mitigation strategies.
