T1057 - 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](https://attack.mitre.org/techniques/T1057) 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.

Atomic Tests

• Atomic Test #1 - Process Discovery - ps

• Atomic Test #2 - Process Discovery - tasklist

Atomic Test #1 - Process Discovery - ps

Utilize ps to identify processes.

Upon successful execution, sh will execute ps and output to /tmp/loot.txt.

Supported Platforms: macOS, Linux

Inputs:

Name	Description	Type	Default Value
output_file	path of output file	path	/tmp/loot.txt

Attack Commands: Run with sh!

ps >> #{output_file}
ps aux >> #{output_file}

Cleanup Commands:

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

Attack Commands: Run with command_prompt!
