Detects attempts to masquerade as legitimate files by adding a space to the end of the filename.
Detects the expiration of the grace period of Windows Defender. This means protection against viruses, spyware, and other potentially unwanted software is disabled.
Detects attempts to disable Windows EventLog autologger sessions via registry modification.
The AutoLogger event tracing session records events that occur early in the operating system boot process.
Applications and device drivers can use the AutoLogger session to capture traces before the user logs in.
Adversaries may disable these sessions to evade detection and prevent security monitoring of early boot activities and system events.

Detects the use of PowerShell to execute the 'Set-MpPreference' cmdlet to configure Windows Defender's threat severity default action to 'Allow' (value '6') or 'NoAction' (value '9').
This is a highly suspicious configuration change that effectively disables Defender's ability to automatically mitigate threats of a certain severity level.
An attacker might use this technique via the command line to bypass defenses before executing payloads.
