A news released by fairly reputation Chinese news site 17173 include a bitorrent link to the 'patch.'

Rumors of impending release of TBC 3.05 continues in the CWDG chatroom. A news released by fairly reputation Chinese news site 17173 include a bitorrent link to the 'patch.' http://download.17173.com/121/11/54340/

Very soon after, about 2 hours since I saw the discussion in the chatroom, someone posted an official notice by the9 staffs, saying:

0. 切勿轻信和乱下网上流传的一些3.0补丁文件
目前在网上流传的一些3.0补丁安装文件很可能是不安全有木马的，所以在官方正式放出3.0补丁前，希望大家可以安心的等待，以确保自己帐户的安全。
官方公告..

asking players not to download patch from external sites, in case of trojans. Before the official release, that everyone should wait for their own account's safety.
