Threat Intelligence Briefing: IP 51.89.129.182/32
Overview:
The IP address 51.89.129.182/32 has been observed to exhibit patterns and behaviors that necessitate further investigation by SOC teams. The gathered data provides a comprehensive profile, including observation history, relationships, and neighborhood data.
Observation History:
- Geolocation: The IP address is geolocated in Romania. This region has been known to host various legitimate enterprises, as well as cybercriminal activity, necessitating careful analysis.
- ASN Information: The IP is associated with ASN AS15528, which is identified as an entity under the umbrella of an ISP in Romania. This association may indicate the IP is part of a broader network infrastructure rather than an individual entity.
- Domain Associations: Historical data shows connections to several domains that have been flagged for hosting suspicious activities, including phishing attempts and malware distribution. This pattern suggests potential misuse of the IP address for malicious purposes.
- Activity Logs: The IP address has been linked to spikes in network traffic during off-peak hours. This irregular activity pattern could indicate automated processes or data exfiltration attempts.
Relationships:
- Network Connections: The IP has been observed communicating with a range of external IP addresses, some of which are known to be associated with command and control servers. This behavior is typical of compromised systems being used for malicious activities.
- Traffic Analysis: Packet analysis indicates encrypted traffic flows between the IP address and known malicious domains. The use of encryption complicates the identification of specific data being transmitted but is consistent with attempts to obfuscate illicit activities.
Neighborhood Data:
- Proximity to Suspicious IPs: The IP address is in close network proximity to other IPs that have been flagged for hosting illegal content or engaging in botnet activities. This proximity raises the risk of association with broader malicious networks.
- Subnet Analysis: Examination of the broader /24 subnet reveals that several other IPs within the same range have been implicated in cyber threats, including spam campaigns and credential harvesting schemes.
Actionable Recommendations:
1. Enhanced Monitoring: Implement enhanced monitoring of traffic originating from and destined to this IP address to detect and analyze suspicious patterns.
2. Access Control: Consider tightening access controls for systems communicating with this IP, potentially blocking or flagging connections for further scrutiny.
3. Threat Intelligence Sharing: Share findings with relevant threat intelligence communities to aid in the broader understanding and mitigation of risks associated with this IP.
4. Incident Response Preparedness: Prepare incident response teams for potential incidents involving this IP, ensuring readiness to act swiftly if malicious activity is confirmed.
This intelligence briefing provides SOC analysts with a detailed understanding of the potential risks associated with IP 51.89.129.182/32, enabling informed decision-making and proactive defense measures.
