Threat Intelligence Briefing: IP 87.236.176.65/32
Overview:
The IP address 87.236.176.65/32 was observed in connection with a series of network activities. This address is owned by a well-known internet service provider and is primarily associated with hosting various services.
Observation History:
- Recent Activity: The IP address was linked to several connection attempts to multiple endpoints over a period of two weeks. These connection attempts were predominantly from geographically dispersed locations, indicating potential scanning or reconnaissance behavior.
- Traffic Patterns: The observed traffic showed a mix of HTTP and HTTPS protocols, with a notable increase in HTTPS traffic in the latter half of the observation period. This shift suggests a possible attempt to evade detection mechanisms.
Relationships and Associations:
- Hosting Services: 87.236.176.65/32 is associated with hosting services that include content delivery networks (CDNs), e-commerce platforms, and various web applications. This multipurpose use may offer cover for malicious activities due to the high volume of legitimate traffic.
- Known Malware Connections: There were instances where the IP address was detected in conjunction with known malware signatures, particularly in the context of phishing campaigns. These connections were identified through cross-referencing with threat intelligence databases.
Neighborhood Data:
- Subnet Analysis: The subnet containing 87.236.176.65/32 is populated with other IP addresses used for similar hosting and content delivery purposes. There is no significant clustering of malicious activity within the immediate neighborhood, suggesting that any observed threats are more likely isolated incidents rather than a widespread issue.
- Adjacent IP Activities: Neighboring IP addresses have shown sporadic instances of suspicious activity, including port scanning and DNS tunneling attempts. These activities were detected by monitoring systems but did not persist beyond initial attempts.
Conclusions and Recommendations:
- Monitoring: Continue to monitor the IP address for any unusual traffic patterns or associations with known threat actors. Implement deep packet inspection to differentiate between legitimate and potentially malicious traffic.
- Blocking and Filtering: Consider implementing targeted blocking or filtering rules for traffic from this IP address to endpoints that are identified as high-risk or sensitive.
- Alert Configuration: Adjust alert thresholds to account for the legitimate high-volume traffic typically associated with hosting services, ensuring that potential threats are not overlooked due to false positives.
This intelligence briefing provides a factual account based on observed data and should be used to inform security operations and decision-making processes within the SOC team. Further analysis and continuous monitoring are recommended to stay ahead of potential threats associated with this IP address.
