Detects the use of WMIC to invoke XSL files or perform suspicious process creation commands, a technique often used for proxy execution or script-based attacks.
Detects Impacket-style hands-on-keyboard staging: a NeedyMantis bundle file dropped by cmd.exe/wmiprvse.exe/services.exe carrying the distinctive remote-execution fingerprint (ADMIN$ share reference, %COMSPEC% invocation, or 2>&1 output redirection used by wmiexec/smbexec/atexec), followed within 15 minutes by execution referencing the same bundle folder with the same fingerprint. Requiring the ADMIN$/%COMSPEC%/redirection fingerprint on both the copy and the execution -- rather than just matching on common process names like cmd.exe or svchost.exe -- removes the bulk of ordinary software installation and update activity that also uses cmd.exe to stage files.
Detects instances where the Steam service (steamservice.exe) is executing suspicious child processes such as command interpreters or binaries located in unusual paths like Temp, Downloads, or AppData, often indicating an attempt to hide malicious activity under a trusted process.
Detects the use of native Windows utilities such as vssadmin.exe, wmic.exe, and diskshadow.exe to delete volume shadow copies. This is a common technique used by ransomware and other malware to prevent system recovery.
Detects the deletion of Volume Shadow Copies using the Windows Management Instrumentation Command-line (WMIC) utility. This behavior is commonly observed in ransomware attacks, including those attributed to DragonForce and CRPx0, as a method to inhibit system recovery prior to file encryption.
This rule monitors for coordinated persistence efforts by detecting the occurrence of at least two out of three specific persistence techniques (registry run key modification, scheduled task creation, or WMI-based script execution) on the same device within a 30-minute window. It explicitly filters out activities from signed binaries or those occurring in standard system/application directories, focusing on potentially malicious artifacts originating from user-writable locations.
Detects the execution of wmic.exe when launched by uncommon parent processes, specifically mshta.exe or wscript.exe. These parent processes are often associated with the execution of malicious scripts (e.g., .hta or .vbs files), which may use wmic.exe for system discovery or execution of commands, a common pattern in file-based living-off-the-land attacks.
Detects execution of WMI or PowerShell queries by HTA, WScript, or CScript processes to gather system information such as OSLanguage, BIOS, or hardware identifiers. This behavior is indicative of environment-awareness checks used by the Casbaneiro/Ousaban banking trojan to identify sandbox or virtualization analysis environments before proceeding with the infection.
Detects the execution of a .vbs script file that contains '.pdf' in its filename, followed within 5 minutes by the execution of a WMI query via wscript.exe. This behavior is indicative of a malicious VBScript dropper attempting to perform system discovery using WMI.
Detects the execution of Windows Script Host (wscript.exe/cscript.exe) loading WMI-related modules (wbemprox.dll, wbemcomn.dll, etc.). This pattern is often indicative of scripts attempting to query WMI for system information, environment configuration, or locale data, which is a common reconnaissance technique used by malware to identify the victim environment.
Detects the execution of a .vbs script file that contains '.pdf' in its filename, followed within 5 minutes by the execution of a WMI query via wscript.exe. This behavior is indicative of a malicious VBScript dropper attempting to perform system discovery using WMI.
Detects potential malicious VBScript behavior where the script queries system language settings via WMI and subsequently launches a decoy message box commonly associated with initial-stage malware loaders or droppers to deceive users before initiating a payload download.
The following analytic detects WMI token impersonation by identifying `wmiprvse.exe` requesting the query, VM, and duplicate-handle rights associated with WMI process access.
It leverages Sysmon EventCode 10 and checks for access masks that combine PROCESS_QUERY_INFORMATION (0x400), PROCESS_QUERY_LIMITED_INFORMATION (0x1000), PROCESS_VM_OPERATION (0x8), PROCESS_VM_READ (0x10), PROCESS_VM_WRITE (0x20), PROCESS_DUP_HANDLE (0x40), and PROCESS_ALL_ACCESS (0x1f3fff).

Detects suspicious PowerShell command lines indicative of process termination or abnormal enumeration of .NET Framework process directories via WMI. This includes using Stop-Process against specific proxy execution binaries or using Get-CimInstance to inspect sensitive .NET framework directory structures, which may be associated with process hollowing or security product interference.
Detects the execution of PowerShell commands intended to gather system information, such as OS details, boot time, or video controller configurations. These techniques are often used during the discovery phase to profile a target machine before further malicious actions.
Detects the use of native system utilities including wmic, vssadmin, and wbadmin to delete Volume Shadow Copies or the Backup Catalog, as well as the deletion of local snapshots on macOS via tmutil. These actions are common techniques employed by ransomware to prevent system restoration after encryption.
Detects instances where the Steam service (steamservice.exe) is executing suspicious child processes such as command interpreters or binaries located in unusual paths like Temp, Downloads, or AppData, often indicating an attempt to hide malicious activity under a trusted process.
Detects the unknown or suspicious process 'doxc' (or 'doxc.exe') executing common Windows system administration utilities ('wmic.exe', 'fsutil.exe', 'cmd.exe') or command-line arguments typically used for reconnaissance and system information discovery, such as listing logical disks or volume information.
Detects the use of native Windows tools like vssadmin and wmic to delete Volume Shadow Copies. This activity is a common indicator of ransomware or other destructive attacks attempting to inhibit system recovery.

This rule detects command line patterns associated with common Impacket tools (wmiexec, psexec, smbexec) executed via Windows processes (cmd.exe, powershell.exe) or via network connections to ports 445 and 135 initiated by Python processes. These tools are frequently used by adversaries for lateral movement, remote service execution, and command execution on compromised systems.
