After a long hiatus jsunpack.jeek.org is back online. I tried hosting from my apartment for as long as possible but it wasn't working out because my uplink became saturated and I had to put rate restrictions on the server. I was also being regularly kicked offline because either I was performing dns lookups for known malware domains or internet watchdogs would report URIs cached in jsunpack as abuse to the ISP. This is the same code that has been running for a long time and I want to work on a new version that has great new features. I will begin reaching out to some people for help this time to build Jsunpack3000.
I would like to thank everyone who supports my efforts especially Steven Burn. Thank you!

Hey guys, I just added a patch from David Dorsey of Visiblerisk, Inc. (Thanks David, you are a boss!).
Below is a sample PDF you can test with just to see how awesome it is:
David described a lot of the improvements and the analysis he performed at the following blog posts entitled "Analyzing Malicious PDFs or: How I Learned to Stop Worrying and Love Adobe Reader"
Part 1: http://visiblerisk.com/blog/2013/4/8/analyzing-malicious-pdfs-or-how-i-learned-to-stop-worrying-a.html
Part 2: http://visiblerisk.com/blog/2013/4/15/analyzing-malicious-pdfs-or-how-i-learned-to-stop-worrying-a.html
In brief, this update improves pdf.py's XFA parsing, PDF encryption tags, and generally the update will help you to decode some malicious PDFs where jsunpackn.py had trouble decoding them before.
Thanks to David and please if you see any bugs related to this update please report them at https://code.google.com/p/jsunpack-n/issues/list and I'll fix them.

I removed the ability for people to submit URLs and files to http://jsunpack.jeek.org/, partially due to abusive submissions in late May. I brought the submissions interface back online today with some changes to help prevent further abuse. Please let me know if you encounter any sort of problems.
