Threat Intelligence Briefing: IP 4.194.136.151/32
Summary:
The IP address 4.194.136.151/32 was analyzed through various cybersecurity tools to provide a comprehensive profile. The intelligence gathered includes its observation history, network relationships, and neighborhood data to assist SOC analysts in understanding potential threats or benign nature.
Observation History:
- Domain Associations: The IP address has been associated with multiple domains, including some linked to email services and content delivery networks (CDNs). Notable domains detected include those associated with legitimate business operations and services.
- Activity Trends: Historical data indicated periods of increased traffic, commonly correlated with web hosting activities and content distribution. These trends align with typical CDN behavior.
Relationships:
- Network Peers: The IP address has been observed communicating with a range of peer IPs across different Autonomous Systems (AS), indicating a broad network interaction scope. These interactions suggest involvement in legitimate network traffic, consistent with CDN operations.
- Domain Registrations: Analysis of associated domain registrations revealed a mix of commercial entities and service providers. The registration data displayed no immediate red flags, such as WHOIS privacy services, which could indicate malicious intent.
Neighborhood Data:
- Proximity Analysis: Neighboring IP addresses in the same subnet were predominantly associated with cloud-based services and hosting providers. This alignment with cloud infrastructure suggests a benign environment predominantly used for service delivery.
- Traffic Patterns: Traffic analysis showed typical patterns expected from CDN operations, including data requests and content delivery to end-users. There were no anomalous spikes or irregular traffic behaviors that would suggest malicious activity.
Potential Indicators:
- Benign Indicators: The IP address's behavior is consistent with content delivery and hosting services. The absence of suspicious domain links or irregular traffic patterns supports its legitimate use.
- Alert Triggers: No alerts were triggered related to known malicious activities, such as command and control (C2) traffic, malware distribution, or phishing attempts.
Actionable Insights:
- Monitoring: Continue monitoring the IP for any deviations from observed benign behavior. Anomalies in traffic patterns or new domain associations should be investigated further.
- Correlation: Cross-reference any alerts involving this IP with other intelligence sources to ensure comprehensive threat awareness.
- Validation: Validate any detected anomalies with additional data points or third-party threat intelligence feeds to confirm or dismiss potential threats.
This intelligence briefing provides SOC analysts with a detailed understanding of the IP 4.194.136.151/32, highlighting its typical use case and potential areas for continued vigilance.
