What is this random suspicious Security Policy Update in Google Play?

Amazon has always said that one of the differences between it and PlayStore is that Amazon apps are vetted more carefully...

Amazon has amdroid apps!!? The worst are the ones in samsung app store

I started getting the security policy update popping up after installing hackers keyboard go figure. It did update without my permission too
 
Seems this thread still garners interest. Yes, it is a legit Samsung update mechanism. If your phone is rooted/modified, run don't walk to your phone and disable it. I got hosed after an auto update and needed to reflash my ROM due to it reenacting Knox and killing root, which ended up with a bootloop with system level mods. Disabled after reflash and never had this problem again.
