Reverse Engineering Obfuscated Javascript

I keep getting these spam emails which are making it past Gmail’s spam filter. Basically, it looks like a ‘delivery failed’ notification, with an HTML attachment which you are supposed to think is the original email. So you click on the attachment and open it, to find out which email you sent failed to go through. I finally got curious enough to see what exactly was going on. Here’s how the email looks like in Gmail:

Inexpensive PCB manufacturing for hobbyists

I just found this service which provides very inexpensive PCB’s for hobbyists. His pricing structure is very simple: $5 per sq inch, you get three copies of the PCB, and there’s no setup fees and free shipping. He’s doing kind of a BatchPCB thing, but somehow has made the cost less expensive. (BatchPCB is $2.5 per sq inch, you get one copy of the PCB, and there’s a $10 setup/shipping fee). I haven’t tried it yet, but he says he needs more people to use his service, otherwise he loses lots of money, so I think I’ll give it a go.

Oh, and did I mention, it’s with 6 mil minimum trace/spacing?
