This is live now and actively being used for some incredibly cool spyware. There's a fairly detailed analysis of this complicated and carefully planned attack on the link.

Mitigation and recommendations
To protect against these attacks, we recommend that you:

• Update Java to the latest version or simply remove it from
  the system if not used
• Update Microsoft Windows and Office to the latest versions
• Update Adobe Reader to the latest version
• Block traffic to the following domains:
  arabooks.ch
  artas.org
  tsoftonline.com
  www.eamtm.com
  news.grouptumbler.com
• Block traffic to the following IPs:
  200.63.46.23
  194.38.160.153
  95.128.72.24
  72.34.47.186
  188.40.99.143
  85.95.236.114
• Install a security solution capable of detecting these threats such as Kaspersky Internet Security 2013 and scan all
  emails and received documents
• Be wary of opening suspicious documents on your systems; instead, use another computer without an Internet
  connection, a VM, or upload the document to Google Docs for viewing
  In addition, infected PDFs contain the following string, which can be used as a quick way to find them:
  “@34fZ7E*p\”

Very handy being a mac user. No Java installed at all. No Adobe reader as Preview can view PDF's.

Though I have little snitched installed and so will need to look at blocking those sites and links.

Very handy being a Windows 8 user, no Acrobat Reader installed here...

Don't be too cocky, there have been several aimed attacks at Macs in the last couple of weeks.

Very handy being a Linux User - no Acrobat installed here ...

...

I don't know enough about other PDF readers to know if they are safe or not. I guess it largely depends whether they support Javascript.

I've heard some very bad things about Foxit and there have been real attacks on it. For example:

I am fully aware of that. It is always best to be fully prepared.
