Detects suspicious post-exploitation activities, including service creation, local account modification, or security tool tampering, executed as SYSTEM shortly after activity associated with the ADSelfService Plus GINA logon-screen vulnerability (CVE-2026-74849).
Detects lateral movement via SMB by identifying multiple connections to Windows admin shares (ADMIN$ or C$) followed within a 10-minute window by the creation of a remote service, often indicative of techniques like PsExec. This pattern detects suspicious fan-out behavior where a single source host interacts with multiple targets.
Detects the loading or service registration of known vulnerable or malicious signed drivers commonly used in Bring Your Own Vulnerable Driver (BYOVD) attacks. These drivers are leveraged by adversaries to gain kernel-level privileges, bypass security controls, and terminate endpoint protection agents.
Detects a sequence of activity characteristic of lateral movement and credential theft: the deployment or execution of PsExec service followed by the use of Windows utilities (vssadmin, ntdsutil, esentutl) to perform Volume Shadow Copy-based extraction of the NTDS.dit database or SYSTEM hive on the same host.
This rule detects potential unauthorized or suspicious installation of an RMM (Remote Monitoring and Management) agent on a Windows host. It flags cases where a process performs multiple suspicious actions within a 24-hour window, specifically combining the installation or starting of a service related to an RMM agent, the creation of a Windows Firewall rule for the RMM agent executable, and/or the creation of log events related to the installer.

This rule detects a sequence of suspicious activities indicative of malicious driver installation. It identifies the creation of an irregularly named .sys file in temp directories, the use of curl.exe to retrieve symbols for a potentially malicious driver, and the subsequent registration/start of that driver as a Windows system service.

Detects the creation of a Windows service that points to a .sys file located in common temporary directories (Temp, Windows\Temp). This behavior is characteristic of adversaries attempting to load malicious kernel drivers, often for persistence or privilege escalation, such as in Bring Your Own Vulnerable Driver (BYOVD) attacks.
Detects the loading of the Alinubx.sys (aka CcProtect.sys) kernel driver, often dropped as nvfsflt64.sys or registered as NvFsFilter, followed by a rapid, simultaneous termination of security product processes. This activity is indicative of a BYOVD (Bring Your Own Vulnerable Driver) attack chain where kernel-mode primitives are used to terminate EDR/AV processes.
Detects the installation of a new Windows service where the executable path is located in suspicious or uncommon directories (e.g., Temp, Users, AppData) or uses known living-off-the-land binaries (LotLBin) in the command path. This pattern is commonly used by adversaries for persistence and privilege escalation.
Detects the installation of a potential remote monitoring and management (RMM) agent via common tools like msiexec, nssm, or sc.exe, followed by consistent HTTPS beaconing to domains hosted on Azurewebsites.net. This pattern is indicative of unauthorized remote access tools used for command and control.

Detects a sequence of suspicious process executions related to the 'RemoteAgent' application, specifically monitoring for MSI-based installations, NSSM service management, and API checks across a device. The rule aggregates distinct process events per device and flags if two or more distinct indicators are identified within a 14-day window.
Detects the installation of a potential remote monitoring and management (RMM) agent via common tools like msiexec, nssm, or sc.exe, followed by consistent HTTPS beaconing to domains hosted on Azurewebsites.net. This pattern is indicative of unauthorized remote access tools used for command and control.
Detects the creation or modification of a Windows service named 'ProcAuditManager' using 'sc.exe' or 'services.exe' command-line utilities, or by direct modification of the associated registry key. This activity may indicate persistence establishment or service manipulation by an adversary.
Detects the loading or installation of a driver file identified as DCRCVDrv.sys followed within 5 minutes by EDR sensor heartbeat loss or process activity, which is characteristic of attempts to tamper with security software or hide malicious activity via a kernel-mode driver.
Detects the loading of known-vulnerable signed drivers typically associated with 'Bring Your Own Vulnerable Driver' (BYOVD) attacks. These drivers are frequently abused to gain kernel-mode privileges, allowing attackers to disable or terminate EDR, antivirus, and other security processes.
