Detects a sequence where a SharePoint application pool worker process (w3wp.exe) spawns a command shell (cmd.exe, powershell.exe, pwsh.exe) related to SharePoint, followed shortly (within 1 hour) by high-fidelity lateral movement tooling or remote execution techniques (such as PsExec, WMI, PowerShell remoting, or scheduled tasks) on the same host.
Detects a specific sequence of behavior associated with Gryxa data collection and exfiltration. A single process queries system state or logs (scheduled tasks, WMI, event logs), creates an archive file (.zip, .7z, .rar), and establishes an outbound public network connection shortly thereafter.
Detects the use of msxsl.exe or wmic.exe to process .xsl or .xslt files, potentially indicating the execution of embedded scripts. The rule calculates a risk score based on the combination of the utility name, the presence of an XSL/XSLT file reference in the command line, usage of suspicious file paths (e.g., Temp, AppData), and being launched by potentially suspicious parent processes like cmd.exe or powershell.exe.
The following analytic detects the spawning of a PowerShell process as a child or grandchild of commonly abused processes like services.exe, wmiprvse.exe, svchost.exe, wsmprovhost.exe, and mmc.exe.
It leverages data from Endpoint Detection and Response (EDR) agents, focusing on process and parent process names, as well as command-line executions.
This activity is significant as it could indicates lateral movement or remote code execution attempts by adversaries.
If confirmed malicious, this behavior could allow attackers to execute code remotely, escalate privileges, or persist within the environment.

The following analytic detects the execution of a process by `WmiPrvSE.exe`, indicating potential use of WMI (Windows Management Instrumentation) for process creation. This detection leverages data from Endpoint Detection and Response (EDR) agents, focusing on process and parent process relationships. This activity is significant as WMI can be used for lateral movement, remote code execution, or persistence by attackers. If confirmed malicious, this could allow an attacker to execute arbitrary commands or scripts, potentially leading to further compromise of the affected system or network.
The following analytic detects the use of Impacket's `wmiexec.py` tool for lateral movement by identifying specific command-line parameters. It leverages data from Endpoint Detection and Response (EDR) agents, focusing on processes spawned by `wmiprvse.exe` with command-line patterns indicative of Impacket usage. This activity is significant as Impacket tools are commonly used by adversaries for remote code execution and lateral movement within a network. If confirmed malicious, this could allow attackers to execute arbitrary commands on remote systems, potentially leading to further compromise and data exfiltration.
The following analytic detects the execution of wmic.exe with parameters to spawn a process on a remote system. It leverages data from Endpoint Detection and Response (EDR) agents, focusing on command-line executions and process telemetry mapped to the `Processes` node of the `Endpoint` data model. This activity is significant as WMI can be abused for lateral movement and remote code execution, often used by adversaries and Red Teams. If confirmed malicious, this could allow attackers to execute arbitrary code on remote systems, facilitating further compromise and lateral spread within the network.
The following analytic detects the execution of WMI command lines used to create or execute processes. It leverages data from Endpoint Detection and Response (EDR) agents, focusing on command-line events that include specific keywords like "process," "call," and "create." This activity is significant because adversaries often use WMI to execute malicious payloads on local or remote hosts, potentially bypassing traditional security controls. If confirmed malicious, this behavior could allow attackers to execute arbitrary code, escalate privileges, or maintain persistence within the environment, posing a severe threat to organizational security.
The following analytic detects the use of WMIC (Windows Management Instrumentation Command-line) for reconnaissance and system information discovery on Windows endpoints.
It identifies command-line queries targeting common Win32 WMI classes such as Win32_OperatingSystem, Win32_Processor, csproduct, Win32_DiskDrive, and Win32_PhysicalMemory, which are frequently leveraged to enumerate hardware, operating system details, and system configuration. Adversaries often use these queries during post-exploitation to fingerprint hosts, assess virtualization, and tailor follow-on activity. While WMIC usage can be legitimate for administrative and inventory tasks, suspicious or unexpected execution—particularly by non-administrative users or uncommon parent processes—may indicate malicious reconnaissance aligned with system discovery techniques.

Detects WmiPrvSE.exe spawning a child process executable from a user-writable AppData\Local folder, which often results from a .NET process invoking ManagementClass(Win32_Process).Create.
The following analytic detects the execution of `powershell.exe` with command-line arguments that utilize the `Get-WmiObject` cmdlet to discover remote systems, specifically targeting the `DS_Computer` parameter.
This detection leverages data from Endpoint Detection and Response (EDR) agents, focusing on process names and command-line executions.
This activity is significant as it indicates potential reconnaissance efforts by adversaries to enumerate domain computers and gather situational awareness within Active Directory.
If confirmed malicious, this behavior could allow attackers to map the network, identify critical systems, and plan further attacks, potentially leading to unauthorized access and data exfiltration.

If confirmed malicious, this behavior could allow attackers to map the network, identify critical systems, and plan further attacks, potentially leading to unauthorized access and data exfiltration.
The following analytic detects the creation of a New-CIMSession cmdlet followed by the use of the Invoke-CIMMethod cmdlet within PowerShell. It leverages PowerShell Script Block Logging to identify these specific cmdlets in the ScriptBlockText field. This activity is significant because it mirrors the behavior of the Invoke-WMIMethod cmdlet, often used for remote code execution via NTLMv2 pass-the-hash authentication. If confirmed malicious, this could allow an attacker to execute commands remotely, potentially leading to unauthorized access and control over targeted systems.
The following analytic detects the execution of `wmic.exe` with the `node` switch, indicating an attempt to spawn a local or remote process. This detection leverages data from Endpoint Detection and Response (EDR) agents, focusing on process creation events and command-line arguments. This activity is significant as it may indicate lateral movement or remote code execution attempts by an attacker. If confirmed malicious, the attacker could gain remote control over the targeted system, execute arbitrary commands, and potentially escalate privileges or persist within the environment.
The following analytic identifies system information discovery techniques, such as the execution of commands like `wmic qfe`, `systeminfo`, and `hostname`. It leverages data from Endpoint Detection and Response (EDR) agents, focusing on process execution logs. This activity is significant because attackers often use these commands to gather system configuration details, which can aid in further exploitation. If confirmed malicious, this behavior could allow attackers to tailor their attacks based on the discovered system information, potentially leading to privilege escalation, persistence, or data exfiltration.
The following analytic detects `wmic.exe` loading a remote XSL script
via a URL. This detection leverages Endpoint Detection and Response (EDR) data,
focusing on command-line executions that include HTTP/HTTPS URLs and the /FORMAT
switch. This activity is significant as it indicates a potential application control
bypass, allowing adversaries to execute JScript or VBScript within an XSL file.
If confirmed malicious, this technique can enable attackers to execute arbitrary
code, escalate privileges, or maintain persistence using a trusted Windows tool,
posing a severe threat to the environment.
