T1007 - System Service Discovery

Description from ATT&CK

Adversaries may try to gather information about registered local system services. Adversaries may obtain information about services using tools as well as OS utility commands such as sc query, tasklist /svc, systemctl --type=service, and net start.

Adversaries may use the information from System Service Discovery during automated discovery to shape follow-on behaviors, including whether or not the adversary fully infects the target and/or attempts specific actions.

Atomic Tests

• Atomic Test #1 - System Service Discovery

• Atomic Test #2 - System Service Discovery - net.exe

• Atomic Test #3 - System Service Discovery - systemctl/service

Atomic Test #1 - System Service Discovery

Identify system services.

Upon successful execution, cmd.exe will execute service commands with expected result to stdout.

Supported Platforms: Windows

auto_generated_guid: 89676ba1-b1f8-47ee-b940-2e1a113ebc71

Attack Commands: Run with command_prompt! Elevation Required (e.g. root or admin)

tasklist.exe
sc query
sc query state= all

Atomic Test #2 - System Service Discovery - net.exe

Enumerates started system services using net.exe and writes them to a file. This technique has been used by multiple threat actors.

Upon successful execution, net.exe will run from cmd.exe that queries services. Expected output is to a txt file in in the temp directory called service-list.txt.

Supported Platforms: Windows

auto_generated_guid: 5f864a3f-8ce9-45c0-812c-bdf7d8aeacc3

Inputs:

Name	Description	Type	Default Value
output_file	Path of file to hold net.exe output	path	%temp%\service-list.txt

Attack Commands: Run with command_prompt!

net.exe start >> #{output_file}

Cleanup Commands:

del /f /q /s #{output_file} >nul 2>&1

Atomic Test #3 - System Service Discovery - systemctl/service

Enumerates system service using systemctl/service

Supported Platforms: Linux

auto_generated_guid: f4b26bce-4c2c-46c0-bcc5-fce062d38bef

Attack Commands: Run with bash!

if [ "$(uname)" = 'FreeBSD' ]; then service -e; else systemctl --type=service; fi;
