This rule detects the creation of scheduled tasks using names that masquerade as legitimate update services for Microsoft Edge, OneDrive, or Windows. Adversaries often use these names to hide persistence mechanisms within the Task Scheduler to maintain system access.
Detects the clearing of Windows event logs using the native 'wevtutil.exe' command or the PowerShell 'Clear-EventLog' cmdlet. This activity is commonly associated with anti-forensic techniques used by threat actors and wiper malware to obstruct incident response efforts and remove traces of malicious activity.
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 SoftEther VPN bridge dropper/installer disguised as svchost.exe with masquerading MixedRealityOpen service, based on install script and dropped files (a.Bat, hamcore.se2, vpn_server.config)

This rule detects the creation of a scheduled task intended to run an executable named 'wsc_updata.exe' from a temporary directory, or identifies svchost.exe initiating a process from that location. Such behavior is indicative of potential persistence mechanisms where malicious actors attempt to run code from unauthorized or writable directories under the context of system processes or scheduled tasks.
Detects attempts to modify or disable the Windows Update service (wuauserv) using command-line utilities (sc.exe, cmd.exe, powershell.exe) in a context involving 'LockAppHost.exe'. This pattern is often associated with unauthorized attempts to tamper with security update mechanisms to prevent system patching.
Detects suspicious service installation patterns involving WmiPrvSE, common in lateral movement techniques.
Detects remote service creation consistent with PsExec-style lateral movement by correlating network logons (Type 3) with subsequent service installations.

Detects unauthorized remote write operations (via SMB, Named Pipes, or TCP) to the Windows Certificate Services CertLog directory (C:\Windows\System32\CertLog\). This directory contains sensitive CA database, transaction logs, and checkpoint files. Any modification by a process other than the legitimate certsvc.exe is indicative of potential CA database tampering, malicious log manipulation, or anti-forensics activity.
Detects attempts to modify or disable the Windows Update service (wuauserv) using command-line utilities (sc.exe, cmd.exe, powershell.exe) in a context involving 'LockAppHost.exe'.

This pattern is often associated with unauthorized attempts to tamper with security update mechanisms to prevent system patching.
Detects attempts to install or modify the 'WMI Provider Host' (WmiPrvSE) service, which is a common technique used by adversaries for persistence or to masquerade malicious activity. The rule monitors process execution, registry modifications, and service installation events specifically targeting this service name.

Detects a sequence of commands characteristic of the Stealer/1.0 malware, involving the systematic disabling of security features including Windows Defender, Firewall, UAC, System Restore, Windows Recovery Environment, SafeBoot, and the deletion of Volume Shadow Copies as a precursor to destructive data operations.
Detects the use of 'bootsect.exe' with parameters specifically designed to overwrite the Master Boot Record (MBR) and the targeting or modification of 'winload.efi', which is indicative of destructive boot-level attacks or bootkit deployment attempts.
Detects inline execution of PowerShell code from a file
