I did not look at the malware, but it is pretty obvious you have been compromised.
Defacements today (unless for specific reason of being "seen") are about leaving the site the same way you find it, and infecteing its user base/visitors.
A second option is that you are secure but a "partner" such as ad sites has been compromised and infects your users.
Naturally, a compromise can come from anywhere, but in most cases it is something like RFI... Taosecurity linked to three great papers on the subject of web botnets / cross-platform web malware:
