The Null Device

Someone is sending pro-Tibet groups documents infected with keylogging malware, configured to send back keystrokes to a server in China. The documents are sent from addresses forged to resemble human rights groups, and purport to be details of Chinese massacres in Tibet and similar information.

The exploit silently drops and runs a file called C:\Program Files\Update\winkey.exe. This is a keylogger that collects and sends everything typed on the affected machine to a server running at xsz.8800.org. And 8800.org is a Chinese DNS-bouncer system that, while not rogue by itself, has been used over and over again in various targeted attacks.

The exploit inside the PDF file was crafted to evade detection by most antivirus products at the time it was sent.

Somebody is trying to use pro-Tibet themed emails to infect computers of the members of pro-Tibet groups to spy on their actions.
