Downloader serves as a downloading/ updating component for other malicious files. Generally it makes internet connections without user's knowledge.

Downloader-AYB is installed via a specifically crafted Microsoft PowerPoint document that exploited a Microsoft Office vulnerability. This document was heuristically detected as the Exploit-MS06-012 trojan.

Upon execution, the trojan spawns a hidden Internet Explorer (iexplore.exe) process and executes as a thread of this process. It then attempts to download one or more file(s) from the following website(s):

  • www.the(hidden)st.com.tw
  • 61.218.(hidden)

The URLs attempted by Downloader-AYB were unavailable at the time of writing.

 

Unexpected connections from iexplorer.exe to the following website(s):
