T1560.001 Archive via Utility
Sub-technique of: T1560
High-Level Description
Adversaries may use utilities to compress and/or encrypt collected data prior to exfiltration. Many utilities include functionalities to compress, encrypt, or otherwise package data into a format that is easier/more secure to transport.
Adversaries may abuse various utilities to compress or encrypt data before exfiltration. Some third party utilities may be preinstalled, such as tar on Linux and macOS or zip on Windows systems.
On Windows, diantz or makecab may be used to package collected files into a cabinet (.cab) file. diantz may also be used to download and compress files from remote locations (i.e. Remote Data Staging). xcopy on Windows can copy files and directories with a variety of options. Additionally, adversaries may use certutil to Base64 encode collected data before exfiltration.
Adversaries may use also third party utilities, such as 7-Zip, WinRAR, and WinZip, to perform similar activities.

What to Check
How to Test
Atomic Red Team Tests
The following tests are from Atomic Red Team and provide actionable ways to test this technique:
Atomic Test 1: Compress Data for Exfiltration With Rar
An adversary may compress data (e.g., sensitive documents) that is collected prior to exfiltration.
When the test completes you should find the txt files from the %USERPROFILE% directory compressed in a file called T1560.001-data.rar in the %USERPROFILE% directory
Supported Platforms: windows
