Detects the loading or usage of the malicious driver 'DCRCVDrv.sys' associated with the ClearFake crypto stealer campaign, which uses a Bring-Your-Own-Vulnerable-Driver (BYOVD) technique to interact with the device path '\Device\DCRCVDRV_U' to terminate or impair EDR and security tools.
Detects attempts to crash or terminate the Kaspersky Antivirus process (avp.exe), as well as associated events indicating the service has been stopped or is encountering abnormal fault conditions. This behavior is indicative of an adversary attempting to disable security software.
Detects instances where the ESET Remote Administrator Agent (ERAAgent.exe) modifies registry keys related to Windows network security settings, such as LSA policies, NullSession pipes/shares, or server/workstation auto-sharing. These settings can be manipulated to weaken Windows security posture, potentially facilitating lateral movement or credential access.
This rule detects instances where LockAppHost.exe or a variation of it (likely used as a proxy) initiates processes or command-line arguments that interact with Windows services, scheduled tasks, or Windows Defender configurations. This behavior is indicative of an adversary attempting to disable security features, suppress Windows updates, or manipulate system services to evade detection.
This rule detects the use of the LockAppHost process to execute suspicious commands associated with tampering with security configurations, including Windows Defender settings, service management (sc.exe), and task scheduling. Adversaries may abuse this process to bypass security controls, disable real-time monitoring, or maintain persistence.

Adversaries may abuse this process to bypass security controls, disable real-time monitoring, or maintain persistence.
Detects modifications to the Windows Registry that disable Microsoft Defender Tamper Protection. Tamper Protection is a security feature that prevents malicious changes to security settings, including the disabling of antivirus and real-time monitoring.
Detects attempts to tamper with Microsoft Windows Defender configuration, specifically by modifying exclusion paths via PowerShell cmdlets (Add-MpPreference, Set-MpPreference), direct registry modifications, or forced Group Policy updates. It also monitors for the disabling of Tamper Protection via registry and the creation of scheduled tasks designed to apply Defender exclusions.

This rule detects unauthorized modifications to browser search provider settings in the Windows Registry, targeting keys associated with Chrome and Microsoft Edge search configuration. This activity is often indicative of browser hijacking or search engine redirection campaigns, such as the NinjaMare malware.
This rule detects unauthorized modifications to sensitive Windows registry keys related to SCHANNEL ciphers, protocols, or FIPS algorithm policies. It specifically identifies when these security settings are weakened (e.g., enabling insecure algorithms or disabling security defaults) by interactive users rather than authorized system processes or configuration management tools like Intune or SCCM.
Detects multiple methods of tampering with Windows security controls, including disabling Windows SmartScreen via registry, bulk removal of Mark-of-the-Web (Zone.Identifier) via scripting, and disabling driver signature enforcement (TestSigning/NoIntegrityChecks) using BCDedit. These actions are indicative of an adversary attempting to bypass security protections to facilitate the execution of untrusted or malicious code.

These actions are indicative of an adversary attempting to bypass security protections to facilitate the execution of untrusted or malicious code.
Detects unexpected crashes of major security software agents (e.g., Antivirus, EDR) that are not associated with authorized vendor update or installation activities, potentially indicating tampering or exploitation attempts to disable security controls.
Detects the restoration of files from the defender quarantine
This rule detects potentially malicious activity involving the manipulation of Windows services using 'sc.exe' to stop or delete services, combined with the forceful termination of 'svchost.exe' processes via 'wmic.exe'. This pattern is often associated with adversaries attempting to disable security tools, logging agents, or other defensive mechanisms on an endpoint.
Detects modifications to the PostgreSQL configuration file 'pg_hba.conf' closely followed by a reload command (via pg_ctl or postgres processes). This behavior is indicative of an attacker attempting to modify authentication or connection access controls for a database.

This detection identifies attempts to create or modify Windows Quality of Service (QoS) policy registry entries under:
HKLM\SOFTWARE\Policies\Microsoft\Windows\QoS
where the configured QoS policy references Microsoft Defender for Endpoint components, including SenseIR, MsSense, WinDefend, or MsMpEng. Such modifications may be indicative of the EDRChoker technique, which abuses Windows QoS policies to throttle network bandwidth or degrade communications associated with Endpoint Detection and Response (EDR) solutions, potentially impacting security monitoring and telemetry collection.
The query captures registry modifications targeting these security-related binaries and provides visibility into the initiating user account, process, command line, and parent process responsible for the change. This activity should be validated to determine whether it was performed as part of legitimate system administration or represents an attempt to impair endpoint protection capabilities.
