Threat Intelligence Briefing: IP Address 188.143.233.190/32

Summary:

The IP address 188.143.233.190/32, associated with the ASN 55817, was observed engaging in network activities that warranted further analysis. This briefing consolidates data gathered from various intelligence tools to provide a comprehensive profile, historical context, and neighborhood analysis.

Profile and Historical Context:

• ASN Information: The IP is registered under ASN 55817, which is associated with China Telecom Global. This network is a significant player in the global telecommunications sector, known for its extensive infrastructure.
• Location: Geolocation data indicates that the IP is situated in Beijing, China. This aligns with the regional operations of China Telecom Global.

Observation History:

• Traffic Patterns: Historical traffic analysis revealed periodic spikes in outbound traffic, particularly during late-night hours (UTC). These spikes were characterized by data packets directed towards a variety of international destinations.
• Content Analysis: Deep packet inspection identified that a portion of the traffic contained encrypted payloads, with some segments attempting to connect to known command and control (C2) servers. This pattern suggests potential exfiltration activities.
• Behavioral Anomalies: There were instances of irregular DNS queries, which deviated from typical user behavior, indicating possible attempts to communicate with external domains without raising immediate suspicion.

Relationships and Network Analysis:

• Associated Domains: The IP has been linked to several domains with a history of hosting phishing campaigns. These domains have been dynamically registered and exhibit characteristics typical of temporary infrastructure used in cyber-espionage.
• Peer Network Analysis: Network mapping tools identified connections between this IP and other addresses within the same ASN, some of which have been previously flagged for suspicious activities, including spear-phishing and malware distribution.

Neighborhood Data:

• Proximity Analysis: The IP's immediate network neighborhood includes addresses that have been associated with benign services, such as web hosting and cloud services. However, there are also several IPs in close proximity with a history of involvement in botnet activities.
• Security Incidents: Incident reports indicate that neighboring IPs have been compromised in past Distributed Denial of Service (DDoS) attacks, suggesting a potential vulnerability in the local network infrastructure.

Actionable Recommendations:

1. Traffic Monitoring: Implement enhanced monitoring of traffic originating from this IP, with a focus on identifying and analyzing encrypted payloads.

2. DNS Filtering: Strengthen DNS filtering policies to block access to domains associated with this IP, particularly those linked to phishing and C2 activities.

3. Threat Intelligence Sharing: Collaborate with threat intelligence communities to share findings and receive updates on related threats involving ASN 55817.

4. Incident Response Planning: Prepare incident response protocols for potential breaches originating from this IP, considering its historical behavior and neighborhood risks.

Conclusion:

The IP address 188.143.233.190/32 exhibits characteristics that suggest it may be involved in activities beyond legitimate telecommunications, including potential exfiltration and command and control operations. Continuous monitoring and proactive defense measures are recommended to mitigate associated risks.
