They have a Tell

 I have discovered that even a simple game of Duces Wild on the computer is not safe from hackers.

The photo you will see below is not photo-shopped.  It appears just as it did on my monitor.

Apparently, while we are busy having fun playing cards, hackers are at work behind the scenes scavenging whatever they can from our system.

I know this because when they manipulated these playing cards, they replaced the two cards on the left, but put them in backwards.    

A Rookie Mistake.
