Process Discovery
Description from ATT&CK
Adversaries may attempt to get information about running processes on a system. Information obtained could be used to gain an understanding of common software/applications running on systems within the network. Adversaries may use the information from Process Discovery during automated discovery to shape follow-on behaviors, including whether or not the adversary fully infects the target and/or attempts specific actions.
In Windows environments, adversaries could obtain details on running processes using the Tasklist utility via cmd or Get-Process via PowerShell. Information about processes can also be extracted from the output of Native API calls such as CreateToolhelp32Snapshot. In Mac and Linux, this is accomplished with the ps command. Adversaries may also opt to enumerate processes via /proc.
On network devices, Network Device CLI commands such as 1
show processes

ps >> #{output_file}
ps aux >> #{output_file}
Cleanup Commands:
1
2
rm #{output_file}
Atomic Test #2 - Process Discovery - tasklist
Utilize tasklist to identify processes.
Upon successful execution, cmd.exe will execute tasklist.exe to list processes. Output will be via stdout.
Supported Platforms: windows
auto_generated_guid: c5806a4f-62b8-4900-980b-c7ec004e9908
Inputs:
None
Attack Commands: Run with command_prompt!
1

tasklist
Atomic Test #3 - Process Discovery - Get-Process
Utilize Get-Process PowerShell cmdlet to identify processes.
Upon successful execution, powershell.exe will execute Get-Process to list processes. Output will be via stdout.
Supported Platforms: windows

Get-Process
Atomic Test #4 - Process Discovery - get-wmiObject
Utilize get-wmiObject PowerShell cmdlet to identify processes.
Upon successful execution, powershell.exe will execute get-wmiObject to list processes. Output will be via stdout.
Supported Platforms: windows

Atomic Test #5 - Process Discovery - wmic process
Utilize windows management instrumentation to identify processes.
Upon successful execution, WMIC will execute process to list processes. Output will be via stdout.
Supported Platforms: windows

wmic process get /format:list
Atomic Test #6 - Discover Specific Process - tasklist
Adversaries may use command line tools to discover specific processes in preparation of further attacks. Examples of this could be discovering the PID of lsass.exe to dump its memory or discovering whether specific security processes (e.g. AV or EDR) are running.
Supported Platforms: windows
auto_generated_guid: 11ba69ee-902e-4a0f-b3b6-418aed7d7ddb
Inputs:
| Name | Description | Type | Default Value |
|---|---|---|---|
| process_to_enumerate | Process name string to search for. | string | lsass |
Attack Commands: Run with command_prompt!
1
2
tasklist | findstr #{process_to_enumerate}
