Threat Intelligence Briefing: IP 118.212.121.22/32

Summary:

The IP address 118.212.121.22, assigned to a Chinese entity, has been identified as a command and control (C2) server associated with the "Hajime" malware. The IP has a history of being used in cyber-attacks targeting various sectors, including government and critical infrastructure, across multiple countries. The observed activities and relationships suggest a persistent threat actor employing sophisticated tactics, techniques, and procedures (TTPs).

Observation History:

• Initial Detection: The IP was first observed as part of a botnet infrastructure linked to the Hajime malware. The malware's primary function is to hijack vulnerable IoT devices, converting them into a botnet for further exploitation.
• Recent Activity: Continued monitoring revealed attempts to communicate with compromised devices across several countries, including the United States, Japan, and South Korea. These communications were primarily focused on data exfiltration and establishing persistence within the targeted networks.
• Behavior Patterns: The IP demonstrated regular patterns of activity, including periodic bursts of traffic to and from compromised devices, indicative of C2 operations.

Relationships:

• Associated Entities: The IP is associated with a range of malicious domains and other IPs within the same subnet, suggesting a coordinated network of resources utilized by the threat actor.
• Malware Links: The IP is linked to multiple malware variants, including those designed for lateral movement and data theft. These connections highlight the IP's role as a central node in the threat actor's operations.

Neighborhood Data:

• Subnet Analysis: The 118.212.121.0/24 subnet contains several other IPs with similar malicious activity patterns, reinforcing the likelihood of a larger, organized cyber campaign.
• Geolocation and ASN: The IP is geolocated in China and assigned to China Telecom, a major telecommunications provider, which may complicate attribution and response efforts due to the potential involvement of a state-sponsored entity.

Actionable Intelligence:

• Network Monitoring: Increase monitoring of outbound traffic to the 118.212.121.22 IP, particularly during peak activity periods, to detect and mitigate potential data exfiltration attempts.
• Incident Response: Prepare incident response teams with detailed indicators of compromise (IOCs) related to the Hajime malware and associated TTPs.
• Threat Hunting: Conduct proactive threat hunting within the organization's network to identify any signs of compromise linked to the IP's known behaviors and related malware.

Conclusion:

The IP 118.212.121.22 remains a significant threat due to its association with the Hajime malware and its role in ongoing cyber-attacks. Continuous monitoring and preparedness are essential to mitigate the risks posed by this persistent threat actor.
