Summary:
Found this compromised site by chance. The payload was identified as ZeuS Panda by @Antelox who stated the C2’s were offline. I presume this is why there was no further infection.
As there was not much to say here, I shortened the picture. It seems to be regular Sundown EK.
Background Information on Sundown EK:
Sundown EK has changed so much over the past few months that I’m not sure any article can cover what it is today. Sundown is known to use parts of other exploit kits. It has also been reported that the source code of Sundown has leaked:
