Can someone take a look at this code?
 

I let wordfence run a scan on one of my wp blogs.
My theme header.php is modified. I use twenty twelve btw.

And also, this code was added a bit further down.

its malware. serverside hack.

Yep. Second part looks like it's probably a hack.

looks shady

yea, that 2nd part is an exploit, usually when that happens it's all over the place in 100s of different files...

if you need a hand cleaning it all up, icq: 33375924 or email me at woj#a#t#wojfun#.#c#om to discuss details

Yup, looks like an exploit

This code is encrypted:

It's hard to say what it does, I would just remove it and see what happens. If the website is still fuly functional than it's fine.
