Kali Linux 2019.4 was released last week and with it comes an 'Undercover' mode that can be used to quickly make the Kali desktop look like Windows 10.

Kali is a Linux distribution created for ethical hacking and penetration testing and is commonly used by researchers and red teamers to perform security tests against an organization.

As most people are used to seeing Windows and macOS devices being used, it may look suspicious to see a user running Kali Linux with it's distinctive dragon logo and a Linux environment in an office lobby or other public setting.

With this in mind, in Kali Linux 2019.4 the developers created a new 'Undercover' mode that will make the desktop look similar to Windows 10 in order to draw less suspicion.

"Say you are working in a public place, hacking away, and you might not want the distinctive Kali dragon for everyone to see and wonder what it is you are doing. So, we made a little script that will change your Kali theme to look like a default Windows installation. That way, you can work a bit more incognito. After you are done and in a more private place, run the script again and you switch back to your Kali theme. Like magic!"

This mode is not a perfect replica of Windows 10, but it does a good enough job to trick a passing user. A demonstration of this new undercover mode can be seen below.

To enable the Undercover mode in Kali Linux 2019.4, you should perform these steps:

Open Terminal Type kali-undercover and press enter. Undercover mode will be activated and your desktop will now look similar to Windows. You can now close the Terminal window.

When done using Undercover mode, you can run kali-undercover again to switch back to your normal desktop. The kali-undercover command can also be run directly from the desktop's search.
