This rule detects attempts to acquire Windows credentials by accessing critical registry hives (SAM, SYSTEM, SECURITY) or their shadow copies. It looks for the use of 'reg save' to export hives, as well as direct file access to these hives or their shadow copy variations by non-standard system processes.
Detects modifications to the 'LimitBlankPasswordUse' registry setting to '0'. This modification enables remote network logons for accounts with blank passwords, a technique abused by threat actors like DragonForce for persistence.
Detects the modification of the 'UseLogonCredential' registry value to '1' within the WDigest security package settings. Enabling this setting allows the WDigest authentication protocol to cache cleartext credentials in the LSASS process memory, which is a common technique used by attackers to facilitate credential dumping and facilitate lateral movement.

Detects instances where WScript.exe queries or modifies multiple sensitive Windows Registry keys. This behavior is often associated with script-based malware attempting to modify file associations, persistence mechanisms, or security policies as part of an infection or post-exploitation process.
Detects modifications to Windows Registry keys responsible for network interface DNS configuration (NameServer or DhcpNameServer) where a non-corporate, non-private, and non-loopback DNS server is set. This behavior may indicate an attempt to intercept or redirect network traffic, potentially for command and control or man-in-the-middle operations.

Detects unauthorized processes modifying the registry value 'PONT_STRING' within the Outlook Options General key. This registry value controls the display of content download warnings in Microsoft Outlook. Modifying this key from a non-Outlook process is a technique used by threat actors, such as APT28, to bypass security warnings and facilitate the execution of malicious payloads or content within Outlook.
Detects modifications or creations of registry values within common Windows auto-start locations, specifically the 'Run' and 'Winlogon' keys. These locations are frequently abused by adversaries to maintain persistence on a host. The rule excludes common, legitimate installer and administration processes to reduce noise.
Detects modifications to Windows Registry keys commonly associated with COM hijacking. Attackers modify these keys to redirect legitimate system calls to malicious executables, achieving persistence and potential privilege escalation. This rule monitors for registry value creation or modification in keys related to shell open commands for MS-settings, MSC files, or executables.
This rule detects when VBScript (wscript.exe or cscript.exe) attempts to modify critical system policies in the Windows Registry, specifically those related to 'Policies\System', 'Policies\Windows', or 'UserAccessControl'. This activity can indicate an attempt to alter system behavior, disable security features, or bypass User Account Control (UAC).
Detects the usage of wmic.exe to modify Windows registry via the WMI StdRegProv class write methods (CreateKey, DeleteKey, SetStringValue, etc.).
This behaviour could be potentially suspicious because it uses an alternative method to modify registry keys instead of legitimate registry tools like reg.exe or regedit.exe.
Attackers specifically choose this technique to evade detection and bypass security monitoring focused on traditional registry modification commands.

Detects user or script launching regedit.exe with command lines targeting the specific 'Edgre' run key, which is associated with persistence mechanisms used by the XenoRAT malware.
