Threat Intelligence Briefing: IP 139.28.219.70/32

Observation Summary:

The IP address 139.28.219.70/32 was observed across various networks, displaying patterns that warrant further scrutiny. This report consolidates findings from multiple intelligence tools to present a comprehensive profile of the IP address.

Profile and Ownership:

• The IP address 139.28.219.70 is associated with a range allocated to a telecommunications provider, as identified in WHOIS data. The allocation suggests its use in legitimate network operations, potentially involving infrastructure or services provided by the telecommunications entity.

Behavioral Observations:

• Historical data indicates irregular traffic patterns, including spikes in outbound traffic during off-peak hours, which could suggest data exfiltration attempts or other unauthorized activities.
• The IP address has been linked to connections with known malicious domains, as per domain reputation databases. These connections were observed primarily through DNS query logs, suggesting potential Command and Control (C2) activity.
• Network logs show that this IP address was involved in numerous failed login attempts to various services, hinting at possible brute force or credential stuffing attacks.

Relationships:

• The IP has been seen in association with several other IPs within the same /24 subnet. These IPs have exhibited similar anomalous behaviors, such as high-volume traffic and connections to suspicious domains.
• Peer relationships with other IPs have been observed in traffic analysis, suggesting possible coordination in distributed network activities.

Neighborhood Data:

• The /24 subnet, 139.28.219.0/24, contains multiple IPs flagged for hosting phishing websites. This indicates a potentially compromised or misused segment of the network.
• Traffic analysis reveals that the neighborhood often participates in large-scale botnet activities, with multiple IPs sending traffic to similar external destinations.

Threat Assessment:

• The combination of irregular traffic patterns, associations with malicious domains, and neighborhood activities suggests that 139.28.219.70 could be compromised or misused for malicious purposes.
• The observed behaviors align with common tactics used in cyber threats, such as data exfiltration, botnet operations, and phishing campaigns.

Actionable Recommendations:

• Monitor traffic originating from and destined to 139.28.219.70 for further anomalies, focusing on data exfiltration patterns and connections to known malicious IPs or domains.
• Implement network segmentation and access controls to isolate traffic from the /24 subnet to minimize potential impact.
• Conduct a thorough review of authentication logs to identify and mitigate any ongoing credential-based attacks.
• Engage with the telecommunications provider to verify the legitimacy of the IP's use and request remediation if misuse is confirmed.

This briefing aims to equip SOC analysts with the necessary insights to assess and respond to potential threats associated with IP 139.28.219.70/32 effectively.
