They mention this was "discovered three years ago", but I was sure I remembered this from years back.

I encountered this error in 2005 on a Photoshop version that was 2 or 3 years old. Also, back then you could mirror the scanned bill in some other app and it would open fine in PS. It is funny how this is still front page news in 2015 :P
Me and a friend tried it with a (UK) bank note while we were at school, way back in the 90's, and received a warning about not being allowed to print scanned currency on screen when the scan finished. It might not have been Photoshop we used (Paint Shop Pro springs to mind), but similar detection techniques have been around for a long time!
