The following analytic detects the execution of "dsquery.exe" with arguments targeting `TrustedDomain` queries directly from the command line. This behavior is identified using Endpoint Detection and Response (EDR) telemetry, focusing on process names and command-line arguments. This activity is significant as it often indicates domain trust discovery, a common step in lateral movement or privilege escalation by adversaries. If confirmed malicious, this could allow attackers to map domain trusts, potentially leading to further exploitation and unauthorized access to trusted domains.
The following analytic detects the use of procdump.exe to dump the LSASS
process, specifically looking for the -mm and -ma command-line arguments. It leverages
data from Endpoint Detection and Response (EDR) agents, focusing on process names,
command-line executions, and parent processes. This activity is significant because
dumping LSASS can expose sensitive credentials, posing a severe security risk. If
confirmed malicious, an attacker could obtain credentials, escalate privileges,
and move laterally within the network, leading to potential data breaches and further
compromise of the environment.

Monitoring this activity is crucial as it may indicate an adversary or Red Team enumerating domain groups for situational awareness and Active Directory discovery. If confirmed malicious, this activity could lead to further reconnaissance, privilege escalation, or lateral movement within the network.
The following analytic detects the execution of the `Get-AdGroup` PowerShell cmdlet using PowerShell Script Block Logging (EventCode=4104). This cmdlet is used to enumerate all domain groups, which adversaries may exploit for situational awareness and Active Directory discovery. Monitoring this activity is crucial as it can indicate reconnaissance efforts within the network. If confirmed malicious, this behavior could lead to further exploitation, such as privilege escalation or lateral movement, by providing attackers with detailed information about the domain's group structure.
The following analytic detects the execution of `powershell.exe` with command-line arguments invoking the `GetCurrent` method of the WindowsIdentity .NET class. This detection leverages data from Endpoint Detection and Response (EDR) agents, focusing on process names and command-line executions. This activity is significant as adversaries may use this method to identify the logged-in user on a compromised endpoint, aiding in situational awareness and Active Directory discovery. If confirmed malicious, this could allow attackers to gain insights into user context, potentially facilitating further exploitation and lateral movement within the network.
The following analytic detects the execution of the `GetCurrent` method from the WindowsIdentity .NET class using PowerShell Script Block Logging (EventCode=4104). This method identifies the current Windows user. The detection leverages PowerShell script block logs to identify when this method is called.
