User Behavior Analytics (UBA)

A subject is motivated by ideology to access, destroy, or exfiltrate data, or otherwise violate internal policies in pursuit of their ideological goals.

Ideology is a structured system of ideas, values, and beliefs that shapes an individual’s understanding of the world and informs their actions. It often encompasses political, economic, and social perspectives, providing a comprehensive and sometimes rigid framework for interpreting events and guiding decision-making.

Individuals driven by ideology often perceive their actions as morally justified within the context of their belief system. Unlike those motivated by personal grievances or personal gain, ideological insiders act in service of a cause they deem greater than themselves.

A subject connects their personal device, under a Bring Your Own Device (BYOD) policy, to organization resources, such as on-premises systems or cloud-based platforms. By leveraging this access, the subject exfiltrates sensitive or confidential data. This unauthorized data transfer can occur through various means, including copying files to the personal device, sending data via email, or using cloud storage services.

The subject develops a custom API that monitors specific activities, network traffic, and system changes within the target environment. The API could monitor HTTP/HTTPS requests directed at sensitive endpoints, track modifications to security group settings (such as firewalls or access policies), and identify administrative actions like changes to user accounts, data access requests, or logging configurations.

This tripwire API is embedded within various parts of the environment:

• Cloud Services: It hooks into serverless functions, containers, or virtual machines to monitor access and activity.
• Applications: It integrates into custom-built web applications to observe access to certain URLs, paths, or endpoints.
• Infrastructure Services: It monitors cloud management APIs (e.g., AWS, Azure, Google Cloud) for unusual activities indicative of an investigation.

Once deployed, the tripwire API continuously monitors network traffic, API calls, and system changes for indicators of an investigation. It looks for:

• Known Security Tools: Scanning for network traffic signatures from common security tools (like Nessus or nmap) or patterns associated with incident response teams.
• Unusual Access: Detecting attempts from IP ranges linked to internal security teams or cloud provider security operations centers.
• System Changes: Watching for actions typical of an investigation, such as new logging mechanisms, alterations to IAM roles, or the activation of cloud monitoring services.

The API can use whitelists for expected IP addresses or user accounts, triggering alerts if unexpected access occurs.

Upon detecting activity, the API tripwire can take immediate evasive actions:

• Alert the Subject: It sends covert alerts to an external server controlled by the subject, through an HTTP request, encrypted email, or messaging platform.
• Suspend Malicious Activity: If integrated into a malicious workflow, the API can halt ongoing data exfiltration or malware processes.
• Clean Up Evidence: It triggers scripts to delete logs, clear files, or reset system configurations to hinder forensic analysis.
• Feign Normalcy: It restores access controls and system settings to their default state, masking any signs of unusual activity.
