Threat Intelligence Briefing: IP 101.53.236.155/32

Overview:

IP address 101.53.236.155/32 was observed across multiple data sources, revealing a network profile characterized by mixed traffic patterns and associations with several domains and services. The following briefing encapsulates key findings from the analysis, intended to provide actionable insights for SOC analysts.

Observation History:

1. Traffic Patterns:

- The IP has exhibited a high volume of outgoing HTTP and HTTPS traffic, with notable peaks during specific timeframes. This suggests potential data exfiltration activities or the operation of a command and control (C2) server.

- Anomalies in DNS query patterns were detected, with frequent requests to domains with newly registered TLDs, indicating possible use of domain generation algorithms (DGAs) for evading detection.

2. Associated Domains and Services:

- The IP is associated with several domains, including some flagged for phishing activities. These domains often employ tactics to mimic legitimate services, aiming to deceive users into divulging sensitive information.

- The service logs reveal connections to cloud infrastructure providers, suggesting possible misuse for hosting malicious payloads or facilitating legitimate traffic to obscure malicious activities.

Relationships and Network Context:

1. Peer Associations:

- The IP shares network segments with other addresses previously linked to malware distribution campaigns. This proximity raises the likelihood of collaborative threat activities or shared infrastructure use by threat actors.

- Several neighboring IPs have been involved in distributed denial-of-service (DDoS) attacks, indicating a potential network of compromised systems in the vicinity.

2. Historical Context:

- Historical data indicates that this IP has been part of a larger botnet, with previous incidents of being used as a relay for spam and malware propagation.

Neighborhood Data:

1. Subnet Analysis:

- The subnet to which 101.53.236.155/32 belongs has been identified as a hotspot for cybercriminal activity, with frequent reports of malware hosting and command and control operations.

- Multiple IPs within the same subnet have been blacklisted by cybersecurity firms due to persistent involvement in malicious activities.

Actionable Insights:

• Monitoring and Alerting:

- Implement enhanced monitoring on traffic originating from or directed to this IP. Focus on DNS queries and unusual patterns in HTTP/HTTPS traffic to detect potential exfiltration or C2 communication.

• Threat Hunting:

- Conduct a thorough investigation of associated domains and services linked to this IP. Verify if any internal systems have communicated with these entities, indicating a possible breach or compromise.

• Collaboration:

- Share findings with threat intelligence communities to gather additional insights and corroborate the observed activities with wider threat actor behaviors.

• Mitigation:

- Consider blocking or rate-limiting traffic to/from this IP at the network perimeter to mitigate potential threats while further investigation is conducted.

This intelligence briefing aims to equip SOC teams with the necessary information to proactively address potential threats associated with IP 101.53.236.155/32. Continued vigilance and adaptive security measures are recommended to mitigate any identified risks.
