This rule detects suspicious DLL loads by the 'consent.exe' process. It specifically looks for known DLLs often abused in DLL side-loading or hijacking scenarios, such as 'msimg32.dll', 'version.dll', 'rtworkq.dll', 'wmsgapi.dll', and other DLLs containing 'sh4nya' or 'shanya' in their name. The rule excludes legitimate Microsoft versions of 'wmsgapi.dll' and 'msimg32.dll' based on their SHA1 hashes to reduce false positives. The 'consent.exe' process is associated with User Account Control (UAC) and its abuse can lead to privilege escalation or defense evasion.
Detects execution of Windows LOLBins spawned shortly after a suspicious attachment is written to user accessible paths, a behavior commonly observed in spearphishing campaigns delivering malware loaders and ransomware.
This rule detects the presence of known malicious browser extensions on devices. It identifies extensions based on a curated list of Extension IDs associated with various threats, including Urban VPN, extensions that turned malicious, general malicious browser extensions, and those involved in Chrome extension supply chain attacks. The rule queries `DeviceTvmBrowserExtensions` to find any activated extensions matching these IDs.
This KQL query identifies potential Bring Your Own Vulnerable Driver (BYOVD) activity associated with the Shanya packer by detecting the creation/modification of known vulnerable or malicious driver files (e.g., ThrottleStop.sys, rwdrv.sys, hlpdrv.sys) and their subsequent loads, a technique used to gain kernel access for disabling EDR/AV tools in ransomware attacks.
This rule detects attempts to discover Group Policy settings on a Windows system. It identifies the execution of common command-line interpreters (cmd.exe, powershell.exe, wmic.exe, rundll32.exe) followed by specific commands or PowerShell cmdlets used for GPO enumeration. This includes native Windows commands like 'gpresult' and 'secedit', registry queries for policy settings, and PowerShell cmdlets such as 'Get-GPO' and 'Get-GPResultantSetOfPolicy'. Additionally, it looks for LDAP-related commands or patterns ('ldapsearch', 'groupPolicyContainer') that might indicate GPO discovery via directory services. The rule also correlates these process events with network connections to SYSVOL shares or LDAP ports (389, 636) to further confirm GPO-related activity.

Additionally, it correlates these process events with network connections to SYSVOL shares or LDAP ports (389, 636) that also contain 'groupPolicyContainer' in the URL, indicating potential GPO access. The rule filters out common system processes to reduce noise.
A critical remote code execution vulnerability, CVE-2025-59287, affects Windows Server Update Services (WSUS), enabling unauthenticated attackers to execute arbitrary code via unsafe deserialization in the AuthorizationCookie.
Actively exploited since October 2025, this flaw targets WSUS servers on ports 8530/8531, often leaving forensic artifacts like modified SoftwareDistribution.log files and suspicious process chains involving w3wp.exe or wsusservice.exe spawning cmd.exe, powershell.exe, or net.exe.
The provided KQL query for Microsoft Defender XDR correlates network, file, and process events to detect exploitation attempts.

This rule detects the creation of executable files (.exe, .dll, .pyd) within browser extension folders (Chrome, Edge, Firefox) followed by a related registry modification within a one-hour window. This behavior is indicative of malicious browser extension installation or modification, often used for persistence or data exfiltration.
Detects potential FileFix attacks where a web browser spawns a suspicious child process (e.g., command prompt, PowerShell, MSHTA) via the file upload dialog's address bar.
Enhancement:
This query correlates two queries to find cases where a user accessed RunMRU and then executed a suspicious PowerShell command.
RMU flags are added to get more close records mapped with Registry Access to RunMRU (Clipboard Paste via Run Dialog) Copy Clipboard data.

This rule detects suspicious activity related to Windows Server Update Services (WSUS) that could indicate compromise. It correlates three types of events: 1) external network connections to WSUS ports, 2) modifications to the WSUS log file (SoftwareDistribution.log), and 3) suspicious processes (like cmd.exe, powershell.exe, whoami.exe, net.exe) spawned by WSUS-related processes (w3wp.exe, wsusservice.exe) with specific command-line arguments. The rule aims to identify scenarios where an attacker might be interacting with or manipulating a WSUS server.
