Detects the execution of "wmic" with the "group" flag.
Adversaries may attempt to find local system groups and permission settings.
The knowledge of local system permission groups can help adversaries determine which groups exist and which users belong to a particular group.
Adversaries may use this information to determine which users have elevated permissions, such as the users found within the local administrators group.

Use this query to locate commands related to discovering highly privileged users in an environment, sometimes a precursor to ransomware
This rule detects attempts to enumerate local system groups on Linux. Adversaries often perform this discovery technique to understand the environment and identify users with elevated permissions. The rule triggers on execution of the 'groups' command or on common file viewing utilities (cat, ed, head, less, more, nano, tail, vi, vim) when they are used to read the '/etc/group' file.
Detects enumeration of local system groups. Adversaries may attempt to find local system groups and permission settings
This analytic detects the execution of SharpHound command-line arguments, specifically `-collectionMethod` and `invoke-bloodhound`. It leverages data from Endpoint Detection and Response (EDR) agents, focusing on process names and command-line executions. This activity is significant as SharpHound is commonly used for Active Directory enumeration, which can be a precursor to lateral movement or privilege escalation. If confirmed malicious, this activity could allow an attacker to map out the network, identify high-value targets, and plan further attacks, potentially compromising sensitive information and critical systems.
The following analytic detects the creation of files typically associated with SharpHound, a reconnaissance tool used for gathering domain and trust data. It leverages file modification events from the Endpoint.Filesystem data model, focusing on default file naming patterns like `*_BloodHound.zip` and various JSON files. This activity is significant as it indicates potential domain enumeration, which is a precursor to more targeted attacks. If confirmed malicious, an attacker could gain detailed insights into the domain structure, facilitating lateral movement and privilege escalation.
The following analytic identifies the execution of `net.exe` with command-line arguments used to query global, local and domain groups. It leverages data from Endpoint Detection and Response (EDR) agents, focusing on process names and command-line arguments. This activity is significant as it indicates potential reconnaissance efforts by adversaries to enumerate local or domain groups, which is a common step in Active Directory or privileged accounts discovery. If confirmed malicious, this behavior could allow attackers to gain insights into the domain structure, aiding in further attacks such as privilege escalation or lateral movement.
The following analytic detects the execution of the SOAPHound binary (`soaphound.exe`) with specific command-line arguments. It leverages data from Endpoint Detection and Response (EDR) agents, focusing on process names, command-line arguments, and other process-related metadata. This activity is significant because SOAPHound is a known tool used for credential dumping and other malicious activities. If confirmed malicious, this behavior could allow an attacker to extract sensitive information, escalate privileges, or persist within the environment, posing a severe threat to organizational security.
The analytic detects the use of the `Get-WMIObject Win32_Group` command executed via PowerShell or cmd.exe to enumerate local groups on an endpoint. This activity is often a precursor to privilege escalation or lateral movement, as attackers map out group memberships to identify potential exploitation paths or unauthorized access to sensitive resources.
This analytic identifies the use of the `get-localgroup` command executed via PowerShell or cmd.exe to enumerate local groups on an endpoint. This detection leverages data from Endpoint Detection and Response (EDR) agents, focusing on process names and command-line arguments. Monitoring this activity is significant as it may indicate an attacker attempting to gather information about local group memberships, which can be a precursor to privilege escalation. If confirmed malicious, this activity could allow an attacker to identify and target privileged accounts, potentially leading to unauthorized access and control over the system.
Detects the execution of Accesschk.exe, a Sysinternals utility used for auditing permissions. Adversaries often abuse this tool to discover privileges and access rights on a system, which can aid in privilege escalation or further discovery within the environment.
This rule detects the execution of BloodHound and SharpHound, which are reconnaissance tools used to map Active Directory environments. It identifies these tools by their product name, description, company name, executable image names, and specific command-line arguments often used for data collection, such as 'CollectionMethod All', '--Loop', '--PortScanTimeout', '-JsonFolder', '-ZipFileName', 'DCOnly', and '--NoSaveCache', as well as PowerShell cmdlets like 'Invoke-Bloodhound' and 'Get-BloodHoundData'.
Detects the execution of 'net.exe' or 'net1.exe' with command-line arguments commonly used for discovery activities related to accounts, groups, shares, and services. This rule aims to identify potential reconnaissance or privilege escalation attempts.
Detects enumeration of local system groups on macOS using common command-line utilities such as `dscacheutil`, `cat`, and `dscl`. This activity is often performed by adversaries during the discovery phase to identify privileged accounts or groups for lateral movement or privilege escalation.
Detects the execution of "wmic" with the "group" flag to discover local system groups and their members. This activity can indicate an adversary attempting to map the environment for privilege escalation opportunities.

Adversaries may attempt to find domain-level groups and permission settings.
The knowledge of domain-level permission groups can help adversaries determine which groups exist and which users belong to a particular group.
Adversaries may use this information to determine which users have elevated permissions, such as domain administrators.

Adversaries may use this information to determine which users have elevated permissions, such as domain administrators.
Adversaries may look for folders and drives shared on remote systems as a means of identifying sources of information to gather as a precursor for Collection and
to identify potential systems of interest for Lateral Movement.
Networks often contain shared network drives and folders that enable users to access file directories on various systems across a network.
