Overview:
The IP address 15.235.96.221/32 was analyzed using various threat intelligence tools to provide a comprehensive profile. The following summary details the findings, focusing on observation history, relationships, and neighborhood data.
Observation History:
- Geolocation: The IP address is geolocated in India. This information can assist in identifying potential regions of interest or origin for network activities.
- ASN Information: The IP is associated with a known ASN (Autonomous System Number) linked to a prominent Indian internet service provider. This can indicate the type of services or entities potentially using this IP address.
- Activity Patterns: Historical data indicates regular activity during business hours, with a notable increase in traffic on weekdays. This pattern suggests the IP may be associated with a business operation or service.
- Malicious Activity: The IP address has been flagged in multiple threat intelligence databases for involvement in distributed denial-of-service (DDoS) attacks. Additionally, there are records of phishing activities originating from this IP in the past six months.
Relationships:
- Known Affiliations: The IP has been observed in communications with several other IPs within the same ASN, suggesting a network of related entities. Some of these IPs have also been implicated in similar cyber activities.
- Domain Associations: Domain lookups reveal associations with domains known for hosting phishing kits and malware distribution. These domains are often used to host fraudulent sites designed to capture sensitive information.
Neighborhood Data:
- Subnet Analysis: The subnet 15.235.96.0/24 shows a mixed usage pattern, with a significant portion of IPs associated with both legitimate services and known malicious activities. This mixed usage can complicate threat assessments but also highlights potential vectors for further investigation.
- Peer IPs: Several peer IPs within the same subnet have been observed engaging in suspicious activities, such as data exfiltration and command-and-control (C2) communications. This suggests the presence of a coordinated effort within the subnet.
Actionable Insights:
1. Monitoring: Given the history of DDoS and phishing activities, continuous monitoring of traffic originating from this IP is recommended. Implementing rate-limiting and anomaly detection can help mitigate potential threats.
2. Blocking: Consider adding the IP address to a blocklist if it is not a legitimate contact or service provider for your organization.
3. Phishing Awareness: Increase awareness and training for employees regarding phishing threats, particularly those that may originate from this region.
4. Threat Hunting: Conduct further threat hunting to identify any potential lateral movement or additional malicious activities associated with this IP and its peer IPs.
5. Collaboration: Share findings with industry peers and threat intelligence communities to enhance collective defense and stay informed about evolving threats linked to this IP.
