Take a few minutes and enjoy some poetry, courtesy of Tyler Klingler:

APT APT everywhere I look.
APT APT in every little nook.
APT solutions for needs both big and small.
But most of this APT is not APT at all.

I query Shodan for GoAhead Web.
As a sad thought goes through my head
A moment of grief when I realized
Finding PLCs is no more a surprise.

—

As I monitor the NVD
I find a pattern I should not see
Oh dear, Oh my, can it be
Another vuln for my PLC

Not willing to be entirely unimaginative, I had to add my own:

Don’t share a SCADA selfie
They’re really not that neat
You’ll paint a target on your back
That leads to your defeat
