Runtime Data Manipulation

Linux · macOS · Windowsnothing on this site yetT1565.003 on attack.mitre.org

Adversaries may modify systems in order to manipulate the data as it is accessed and displayed to an end user, thus threatening the integrity of the data. By manipulating runtime data, adversaries may attempt to affect a business process, organizational understanding, and decision making. Adversaries may alter application binaries used to display data in order to cause runtime manipulations.

how MITRE says to see it

Detection Strategy for Runtime Data Manipulation.

  • Monitor for runtime data manipulations by detecting suspicious modification of application binaries, API hooking, or unexpected behavior from processes responsible for rendering or displaying data. Correlate registry edits, process creation, and unexpected binary hash mismatches.
  • Detect runtime manipulation by monitoring system calls for modifications to shared libraries, ELF binaries, or environment variables that affect how data is displayed. Look for suspicious writes to application directories and mismatch in binary integrity baselines.
  • Monitor for runtime manipulation by observing changes in application bundles, unexpected signing modifications, and runtime API calls that inject or alter how data is displayed. Detect alterations in CFNetwork or CoreFoundation frameworks responsible for rendering data.

what reduces it

  • M1030 Network Segmentation. Identify critical business and system processes that may be targeted by adversaries and work to isolate and secure those systems against unauthorized access and tampering.
  • M1022 Restrict File and Directory Permissions. Prevent critical business and system processes from being replaced, overwritten, or reconfigured to load potentially malicious code.
