Going undercover with Kali

Going undercover - make Kali look like Windows 10

With the new Kali 2019.4 release, Kali comes with an ‘undercover’ mode which make the Kali desktop look like Windows 10.

Kali Undercover

Going undercover

At my recent PWK training, we gathered with a group of students in the hotel bar or lobby to spend the evening training what we had learnt that day.

I noticed some strange looks while we were running Kali Linux, instead of some familliar OS like Windows or MacOS. (Or maybe because of our wildy blinking Alfa Wifi adapters, hanging from our laptops…?)

Improving our cover

While this solution is already great, we can just make it a bit better by replacing the undercover background by the original background from Windows 10.

The undercover background can be found at /usr/share/kali-undercover/backgrounds. A quick look shows us the dimensions of 3840x2160.

root@kali:/usr/share/kali-undercover/backgrounds# file Windows-10.jpg 
Windows-10_org.jpg: JPEG image data, progressive, precision 8, 3840x2160, components 3
root@kali:/usr/share/kali-undercover/backgrounds# 

The Windows 10 background can be found at C:\Windows\Web\4K\Wallpaper\Windows.

Now just replace the Windows-10.jpg file with out new background and let’s go undercover.

Kali Undercover Improved

Wrap up

That’s it! The undercover look now is very close to Windows 10. I even get confused running Kali in undercover mode as virtual machine.

I guess we should checkout the newly added powershell next. Powershell is currently available in Kali with the new 2019.4 release.
