T1005 - Data from Local System

Description from ATT&CK

Adversaries may search local system sources, such as file systems and configuration files or local databases, to find files of interest and sensitive data prior to Exfiltration. Adversaries may do this using a [Command and Scripting Interpreter](https://attack.mitre.org/techniques/T1059), such as [cmd](https://attack.mitre.org/software/S0106) as well as a [Network Device CLI](https://attack.mitre.org/techniques/T1059/008), which have functionality to interact with the file system to gather information.(Citation: show_run_config_cmd_cisco) Adversaries may also use [Automated Collection](https://attack.mitre.org/techniques/T1119) on the local system.

Atomic Tests


Atomic Test #1 - Search files of interest and save them to a single zip file (Windows)

This test searches for files of certain extensions and saves them to a single zip file prior to extraction.

Supported Platforms: Windows

auto_generated_guid: d3d9af44-b8ad-4375-8b0a-4bff4b7e419c

Inputs:

| Name | Description | Type | Default Value | |——|————-|——|—————| | starting_directory | Path to starting directory for the search | Path | C:\Users| | output_zip_folder_path | Path to directory for saving the generated zip file | Path | PathToAtomicsFolder\..\ExternalPayloads\T1005| | file_extensions | List of file extensions to be searched and zipped, separated by comma and space | string | .doc, .docx, .txt|

  }

Atomic Test #2 - Find and dump sqlite databases (Linux)

An adversary may know/assume that the user of a system uses sqlite databases which contain interest and sensitive data. In this test we download two databases and a sqlite dump script, then run a find command to find & dump the database content.

Supported Platforms: Linux
