Adversaries may search for common password storage locations to obtain user credentials.
Passwords are stored in several places on a system, depending on the operating system or application holding the credentials.

Detects writing data into NTFS alternate data streams from powershell. Needs Script Block Logging.
Storing files in Alternate Data Stream (ADS) similar to Astaroth malware.
Adversaries may search local file systems and remote file shares for files containing insecurely stored credentials.
These can be files created by users to store their own credentials, shared credential stores for a group of individuals,
configuration files containing passwords for a system or service, or source code/binary files containing embedded passwords.

configuration files containing passwords for a system or service, or source code/binary files containing embedded passwords.
Detects a Get-Process command on lsass process, which is in almost all cases a sign of malicious activity
Adversaries may target user email on local systems to collect sensitive information.
Files containing email data can be acquired from a users local system, such as Outlook storage or cache files.

Once established within a system or network, an adversary may use automated techniques for collecting internal data
Powershell Timestomp
Sigma
Adversaries may modify file time attributes to hide new or changes to existing files.
Timestomping is a technique that modifies the timestamps of a file (the modify, access, create, and change times), often to mimic files that are in the same folder.

Adversaries may establish persistence and elevate privileges by executing malicious content triggered by a Windows Management Instrumentation (WMI) event subscription.
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 suspicious ways to run Invoke-Execution using IEX alias
Detects creation of a new service via "sc" command or the powershell "new-service" cmdlet with suspicious binary paths
Adversaries may log user keystrokes to intercept credentials as the user types them.
Adversaries may attempt to take screen captures of the desktop to gather information over the course of an operation.
Screen capturing functionality may be included as a feature of a remote access tool used in post-compromise operations

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. (Citation: TechNet PowerShell)
Adversaries can use PowerShell to perform a number of actions, including discovery of information and execution of code

Open a handle on the drive volume via the \\.\ DOS device path specifier and perform direct access read of the first few bytes of the volume.
Adversaries may employ various system checks to detect and avoid virtualization and analysis environments.
This may include changing behaviors based on the results of checks for the presence of artifacts indicative of a virtual machine environment (VME) or sandbox
