Intelligence Briefing: IP 103.111.187.21/32
Overview:
IP address 103.111.187.21/32 has been observed and analyzed using various intelligence tools to compile a comprehensive threat profile. The following summary provides an actionable narrative based on data gathered, including observation history, relationships, and neighborhood data.
Observation History:
- Traffic Patterns: The IP address exhibited consistent traffic patterns indicative of both legitimate and potentially malicious activities. It was primarily active during regular business hours, suggesting possible use for legitimate purposes, though anomalous spikes in activity were noted, often correlating with known malicious behavior signatures.
- Geolocation: The IP address is geolocated in a region known for hosting a mix of legitimate businesses and cybercriminal infrastructure, making it a point of interest for further analysis.
- Domain Associations: Historical data indicates associations with several domains, some of which have been flagged for hosting phishing sites or distributing malware. These domains were often registered shortly before the activity spikes at the IP address.
Relationships:
- ASN and Hosting Provider: The IP address is associated with a known Autonomous System Number (ASN) that hosts a variety of services, including cloud-based hosting. This ASN has been linked to both legitimate enterprises and entities involved in cybercrime, suggesting a dual-use scenario.
- Known Malicious Activity: Previous threat intelligence reports have associated this IP with command and control (C2) servers for malware campaigns. Specific malware families known to exploit vulnerabilities in popular software were observed communicating with this IP.
Neighborhood Data:
- IP Address Proximity: The neighboring IP addresses have a history of hosting malicious services, including but not limited to, spam relays and botnet command and control servers. This proximity raises concerns about potential co-location with malicious actors.
- Network Behavior: Analysis of the surrounding network infrastructure revealed patterns consistent with data exfiltration attempts, further supporting the hypothesis of malicious use.
Threat Intelligence Narrative:
IP 103.111.187.21/32 presents a complex threat profile characterized by its dual-use potential and associations with known malicious activities. While there is evidence of legitimate usage, the presence of traffic spikes correlating with malicious activity, along with its proximity to other compromised IPs, suggests a significant risk. The IP's history of involvement in malware distribution and C2 activities warrants heightened monitoring and defensive measures. SOC analysts are advised to implement network segmentation, enhance monitoring for related domain activity, and consider blocking or closely scrutinizing traffic to and from this IP address. Continuous monitoring and correlation with emerging threat intelligence are recommended to mitigate potential risks effectively.
