MITRE ATT&CK Enterprise TechniquesAI

T1005 Data from Local System Collection
Adversaries may search local system sources, such as file systems, configuration files, local databases, virtual machine files, or process memory, to find files of interest and sensitive data prior to Exfiltration.

T1082 System Information Discovery Discovery
An adversary may attempt to get detailed information about the operating system and hardware, including version, patches, hotfixes, service packs, and architecture.

Why these techniques?

Local info disclosure of kernel state directly enables data collection from the system and system information discovery by an app.

Mitigating Controls (NIST 800-53 r5) AI

AC-3 Access Enforcement good match
prevent

Directly enforces authentication checks before allowing any app to access or read sensitive kernel state.

AC-6 Least Privilege good match
prevent

Ensures apps operate under least privilege so they cannot reach or leak kernel internals even if authentication is weak.

SC-39 Process Isolation partial match
prevent

Provides process isolation boundaries that limit an app's ability to observe or extract kernel state.
