Detects usage of the "Import-Module" cmdlet to load the "Microsoft.ActiveDirectory.Management.dl" DLL. Which is often used by attackers to perform AD enumeration.
Detects usage of the "Add-WindowsCapability" cmdlet to add Windows capabilities. Notable capabilities could be "OpenSSH" and others.
Detects usage of the Get-ADComputer cmdlet to collect computer information and output it to a file
Detects attempts of decoding encoded Gzip archives via PowerShell.
Detects calls to cmdlets that are used to export certificates from the local certificate store. Threat actors were seen abusing this to steal private keys from compromised machines.
Detects usage of the "TcpClient" class. Which can be abused to establish remote connections and reverse-shells. As seen used by the Nishang "Invoke-PowerShellTcpOneLine" reverse shell and other.
Detects deletion of Windows Volume Shadow Copies with PowerShell code and Get-WMIObject. This technique is used by numerous ransomware families such as Sodinokibi/REvil
Detects PowerShell command line contents that include a suspicious abnormal casing in the Net.Webclient (e.g. nEt.WEbCliEnT) string as used in obfuscation techniques
Uses PowerShell to install/copy a file into a system directory such as "System32" or "SysWOW64"
Detects PowerShell scripts attempting to disable scheduled scanning and other parts of Windows Defender ATP or set default actions to allow.
Detects PowerShell scripts that make use of the "Compress-Archive" Cmdlet in order to compress folders and files where the output is stored in a potentially suspicious location that is used often by malware for exfiltration.
An adversary might compress data (e.g., sensitive documents) that is collected prior to exfiltration in order to make it portable and minimize the amount of data sent over the network.

Detects changing the PowerShell script execution policy to a potentially insecure level using the "Set-ExecutionPolicy" cmdlet.
Detects Cmdlet names from PowerView of the PowerSploit exploitation framework.
Detects calls to "get-process" where the output is piped to a "where-object" filter to search for security solution processes.
Adversaries may attempt to get a listing of security software, configurations, defensive tools, and sensors that are installed on a system or in a cloud environment. This may include things such as firewall rules and anti-virus

Detects calls to the AtomicTestHarnesses "Invoke-ATHRemoteFXvGPUDisablementCommand" which is designed to abuse the "RemoteFXvGPUDisablement.exe" binary to run custom PowerShell code via module load-order hijacking.
Detects Commandlet names and arguments from the Nishang exploitation framework
Detects a "Get-Process" cmdlet and it's aliases on lsass process, which is in almost all cases a sign of malicious activity
Adversaries may use hidden windows to conceal malicious activity from the plain sight of users.
In some cases, windows that would typically be displayed when an application carries out an operation can be hidden

Adversaries may abuse PowerShell commands and scripts for execution.
PowerShell is a powerful interactive command-line interface and scripting environment included in the Windows operating system

Once established within a system or network, an adversary may use automated techniques for collecting internal data.
Identifies when a user attempts to clear console history. An adversary may clear the command history of a compromised account to conceal the actions undertaken during an intrusion.
