T1653 Power Settings

High-Level Description

Adversaries may impair a system's ability to hibernate, reboot, or shut down in order to extend access to infected machines. When a computer enters a dormant state, some or all software and hardware may cease to operate which can disrupt malicious activity.

Adversaries may abuse system utilities and configuration settings to maintain access by preventing machines from entering a state, such as standby, that can terminate malicious activity.

For example, powercfg controls all configurable power system settings on a Windows system and can be abused to prevent an infected host from locking or shutting down. Adversaries may also extend system lock screen timeout settings. Other relevant settings, such as disk and hibernate timeout, can be similarly abused to keep the infected machine running even if no user is active.

Aware that some malware cannot survive system reboots, adversaries may entirely delete files used to invoke system shut down or reboot.

Kill Chain Phase

• Persistence (TA0003)

Platforms: Windows, Linux, macOS, Network Devices

What to Check

• Identify if Power Settings technique is applicable to target environment
• Check Windows systems for indicators of Power Settings
• Check Linux systems for indicators of Power Settings
• Check macOS systems for indicators of Power Settings
• Verify mitigations are bypassed or absent (1 known mitigations)
• Assess detection coverage (1 detection strategies)

How to Test

Manual Testing

1. Identify Attack Surface: Determine if the target environment is susceptible to Power Settings by examining the target platforms (Windows, Linux, macOS).

2. Assess Existing Defenses: Review whether mitigations for T1653 are in place. If defenses are absent or misconfigured, this technique may be exploitable.

3. Execute Test: Use tools and methods described in the MITRE ATT&CK page and external references below.

Note: No Atomic Red Team tests available for this technique. See Atomic Red Team GitHub for updates.

Remediation Guide

M1047 Audit

Periodically inspect systems for abnormal and unexpected power settings that may indicate malicious activty.
