Not an exaggeration.
Allow a wireless connection to Amazon - your MKK keys will die.
If connecting by 3G - the death of the keys is almost instantaneous.
Both myself and one of our best developers (Geekmaster) just happened to be watching / playing with their Kindles when the attack started.
First thing you will notice is a brand new:
"Test Kindle Installation Report" document will pop up among your documents.
The second thing:
KUAL can't be used to 'fix' whatever was just trashed.
This is the same thing that happened in the past when you changed registration status.
Now it only requires that you make a connection to Amazon.
Touchscreen device owners:
The 'hotfix' package will fix the device for you:

Put it in the top of visible USB storage and use the 'old school' way to install it :: "Update My Kindle" menu entry.
(your only choice, KUAL and MrPI will be dead)
Non-Touchscreen device owners:
Manually (re-)install the MKK package for your device from the selection at:

All device types
You might want to add 'Rescue Pack' now, if you don't have it installed already.
You don't need to know how to use it (now) - we can cross that bridge if we ever need to.

It is too early to say if the BBB firewall can block this malicious damage - and I can't test it myself at the moment (Amazon took their big hammer to my test devices).
Somebody try the BBB firewall and see if your MKK keys disappear when you connect to Amazon.
When (if) I get my own devices restored - I'll check out the BBB rules myself (I am the author of the BBB firewall).
