T0811 Data from Information Repositories
High-Level Description
Adversaries may target and collect data from information repositories. This can include sensitive data such as specifications, schematics, or diagrams of control system layouts, devices, and processes. Examples of information repositories include reference databases in the process environment, as well as databases in the corporate network that might contain information about the ICS.
Information collected from these systems may provide the adversary with a better understanding of the operational environment, vendors used, processes, or procedures of the ICS.
In a campaign between 2011 and 2013 against ONG organizations, Chinese state-sponsored actors searched document repositories for specific information such as, system manuals, remote terminal unit (RTU) sites, personnel lists, documents that included the string SCAD*, user credentials, and remote dial-up access information.
Kill Chain Phase
Platforms: ICS
What to Check
How to Test
Identify Attack Surface
Determine if the target ICS/SCADA environment is susceptible to Data from Information Repositories by examining operational technology systems and network architecture.
Assess Existing Defenses
Review whether mitigations for T0811 are in place. If defenses are absent or misconfigured, this technique may be exploitable in the ICS environment.
Remediation Guide
M0947 Audit
Consider periodic reviews of accounts and privileges for critical and sensitive repositories.
M0941 Encrypt Sensitive Information
Information which is sensitive to the operation and architecture of the process environment may be encrypted to ensure confidentiality and restrict access to only those who need to know.
M0922 Restrict File and Directory Permissions
Protect files with proper permissions to limit opportunities for adversaries to interact and collect information from databases.
M0918 User Account Management
Ensure users and user groups have appropriate permissions for their roles through Identity and Access Management (IAM) controls to prevent misuse. Implement user accounts for each individual that may access the repositories for role enforcement and non-repudiation of actions.
