New Azvhan Bot Family Revealed

A new bot family was found in the wild around April this year. This family was named "Avzhan." Avzhan malware, detected by Trend Micro as Mal_Scar-1, mostly affected Asia where most of the affected users resided.

Avzhan bots install themselves onto the Windows system directory using the file name {six random lower-case letters}.exe. After installation, it deletes its original copy then executes the copy it installed. It registers itself as a service to run at every system startup, as shown by the service named Q MUSCIC below

This malware tries to connect to the following domains to receive instructions from botnet herders:avzhan1.{BLOCKED}2.org

  • ei0813.{BLOCKED}2.org
  • wanmei8013.{BLOCKED}2.org
  • xhsb.{BLOCKED}2.org
