Hacked Zen Carts started appearing after the powers that be at Zen Cart announced some patches last year.  A newly vulnerability was discovered that has led to cart hacking after it was announced!

The one that has caused so many problems simply inserts php code into the images folder and that code usually just needs removing and your cart can be restored to working order.

If you are a Zen Cart owner and you are not subscribed to the announcements thread or your web person doesn’t inform you of the necessity of certain patches, subscribe today!  Otherwise, you are just inviting problems.

So the good news is if you stay on top of what’s happening, you won’t get hacked!  The Zen Cart support community is very proactive and fixes problems before they become problems.  That’s one of the reasons I use Zen and one of the reasons my hosting customers with Zen Carts have so few problems. I watch out for them!
