Detects Microsoft Office applications (Word, Excel, PowerPoint, Outlook, OneNote, Access, Publisher) spawning common command interpreters or scripting engines. This behavior is a common indicator of macro-based malware or malicious document exploitation where Office applications are used as an initial access vector to execute arbitrary code.

Detects the execution of cmd.exe spawned by processes running from suspicious directory paths such as %TEMP%\aswerf\, %APPDATA%\xwreg\, or %APPDATA%\xgdf\. These paths are commonly associated with dropper activity or malicious payloads. The rule specifically monitors for command lines containing '.pdf', suggesting the potential opening of a lure document.

This rule detects potential malicious activity involving the 'wusvc.exe' executable. It flags instances where 'wusvc.exe' is executed from the user's Downloads folder or other non-standard paths, particularly when the file size is abnormally small (less than 100KB), which is indicative of masquerading or a dropper payload. The rule also checks for a known malicious file hash associated with the Snowlight dropper.

This rule detects potentially unauthorized installation of extensions in Visual Studio Code (VSIX) or plugins in JetBrains IDEs (IntelliJ, PyCharm, WebStorm). It flags installations that do not originate from verified official marketplaces, which may indicate the manual installation of malicious or supply-chain compromised development environment extensions.

Detects instances where common video conferencing and collaboration applications (such as Microsoft Teams, Zoom, Webex, or Slack) initiate a command shell (cmd.exe, powershell.exe, or wscript.exe). This behavior is often indicative of social engineering or phishing attacks where an adversary executes malicious code via a meeting invite or chat message.

This rule detects instances where common productivity applications (like Office suite) or web browsers spawn child processes that create system mutexes. This is a common indicator of malicious activity where a benign-looking document or web-based threat launches secondary payloads or persistence mechanisms.

Detects Microsoft Office applications (Word, Excel, PowerPoint) and WordPad spawning command-line interpreters (mshta, wscript, cscript, cmd, powershell, pwsh). This behavior is often associated with macro-based malware or malicious document attachments attempting to execute scripts or shell commands to facilitate further infection stages.

Detects the execution of known living-off-the-land binaries (LOLBins) such as mshta.exe, certutil.exe, bitsadmin.exe, wscript.exe, or cscript.exe directly by explorer.exe. This pattern is indicative of a user-initiated execution, potentially triggered by social engineering lures like the 'ClickFix' technique, where a user is tricked into pasting and running malicious commands in the Windows Run dialog or a command prompt context.

Detects potential BaoLoader drive-by compromise attempts by monitoring two stages: first, the creation of executable files in temporary or application data directories by browser processes; and second, the execution of command-line shells by processes running from those same directories where the browser acted as the grandparent.

003
Detects instances where explorer.exe spawns command-line utilities (cmd.exe, powershell.exe, mshta.exe) with command-line arguments indicative of file downloading or remote execution (e.g., curl, certutil, bitsadmin, Invoke-WebRequest). This pattern is often associated with ClickFix social engineering attacks, where a victim is tricked into pasting malicious commands directly into the Windows Run dialog.

Detects the ClickFix social engineering technique where a user is coerced into copying and executing a malicious script from a web browser. The rule identifies instances where common web browsers spawn script interpreters such as powershell.exe, cmd.exe, mshta.exe, or wscript.exe, which is characteristic of the user pasting malicious commands into a command prompt interface.

Detects the execution of the NetSupport Manager remote access tool (client32.exe) when spawned by web browsers or script interpreters such as PowerShell or MSHTA. This behavioral pattern is frequently associated with malicious delivery chains including ClickFix and CastleLoader, where users are social engineered into downloading or executing suspicious payloads.

This rule detects instances where common web browsers (Chrome, Edge, Firefox, IE, Brave, Opera) spawn common administrative or scripting shells (PowerShell, CMD, mshta, wscript, cscript). This pattern is frequently indicative of drive-by downloads or malicious file execution triggered by social engineering, where an attacker leverages the browser process to spawn execution environments to run malicious scripts or payloads.

001
This rule detects instances where the WhatsApp Desktop application (WhatsApp.exe) spawns suspicious child processes commonly used for scripting or command execution, such as wscript.exe, cscript.exe, powershell.exe, cmd.exe, or rundll32.exe. It specifically excludes known legitimate update and service-related command lines to reduce false positives. This behavior could indicate a phishing attempt or malware execution originating from a compromised WhatsApp session.

Detects a user mounting a deceptive .dmg file that invokes a hidden .sh or .command script upon opening. This rule specifically looks for the 'hdiutil' process attaching a disk image and then correlates it with a process executing a hidden shell script (.sh or .command) from a mounted volume.

Detects suspicious process creations (PowerShell, Cmd, Mshta, Wscript) originating from web browsers, explorer.exe (likely from the Run dialog), or rundll32.exe. This pattern is often associated with social engineering attacks like 'ClickFix' where users are tricked into pasting malicious commands.

Detects activity associated with a specific phishing campaign distributing 'Distribution Settlement Agreement' PDF lures. The rule monitors for file creation or execution of files matching this naming pattern, as well as network connection attempts to domains identified as related to the threat actors: 'gasparinutrition.com' and 'gappssmtp.com'.

Detects a specific attack chain involving the movement of 'update.zip' to the temporary directory, its extraction using 'tar -xf', and the subsequent execution of 'update.bat'. This chain is associated with Clickfix attacks.

Detects the Windows Installer service (msiexec.exe) spawning the command shell (cmd.exe) to execute specific scripts or commands (xupdate.bat or Traiolx). This pattern is often associated with software installers or malicious activity attempting to run commands via child processes spawned by system-level installers.

Detects the execution of hidden shell scripts (.sh or .command) located within a mounted disk image (.dmg). This pattern is commonly used by macOS infostealers which masquerade as legitimate applications (such as Notion, Arc, or Raycast) to trick users into executing malicious code after mounting the deceptive installer.
