Summary:
The IP address 4.235.1.40/32, located within the 4.235.1.0/24 range, has been associated with a series of activities indicative of both legitimate services and potential security threats. Based on the observed data, this IP address is predominantly linked to a known content delivery network (CDN) provider. However, historical data and neighborhood analysis reveal associations with malicious activities.
Observation History:
- Recent Activity: The IP address was observed participating in traffic patterns consistent with legitimate CDN operations, primarily serving as a node for content distribution.
- Historical Activity: Past observations indicate that this IP address was involved in distributing malware campaigns. This includes facilitating the download of exploit kits and acting as a command-and-control (C2) server for botnets.
Relationships:
- Known Affiliations: The IP address is part of a larger network operated by a prominent CDN service, which is known for distributing both legitimate and malicious content.
- Past Malicious Associations: Historical data links the IP to several threat actors who have utilized it for distributing ransomware and conducting phishing operations.
