Wow! - Concise scripting and delivery while still connecting the long trail of dots in how this (and by implication many other) network and computer security problems keep showing up. And all without tech jargon! - I bow in respect!

Thanks!

Fantastic video, really well explained.
I think I am of an age, where I still call the key on the alpha side of the keyboard carriage return and the one on the number pad enter.

Thanks, Mark 🙂

I won't quibble over typewriters vs teletypes
I appreciate this as an example of perimeter security (firewalls) are such a terrible idea. Once you get by them there is no stopping you. We need more nuanced trust models.
