The trojan serves as a backdoor. It can be controlled remotely. The trojan may perform DoS/DDoS attacks.

Installation

When executed, the trojan copies itself into the following location:

  • %appdata%\­%variable%.exe

A string with variable content is used instead of %variable% .


The file is then executed.


In order to be executed on every system start, the trojan sets the following Registry entries:

  • [HKEY_CURRENT_USER\­Software\­Microsoft\­Windows\­CurrentVersion\­Run]
    • "%variable%" = "%appdata%\­%variable%.exe"
  • [HKEY_CURRENT_USER\­Software\­Microsoft\­Windows\­CurrentVersion\­Policies\­Explorer\­Run]
    • "%variable%" = "%appdata%\­%variable%.exe"
  • [HKEY_CURRENT_USER\­Software\­Microsoft\­Windows NT\­CurrentVersion\­Winlogon\­Shell]
    • "Shell" = "Explorer.exe,%appdata%\­%variable%.exe"

The following Registry entries are created:

  • [HKEY_LOCAL_MACHINE\­SYSTEM\­CurrentControlSet\­Services\­SharedAccess\­Parameters\­FirewallPolicy\­StandardProfile\­AuthorizedApplications\­List]
    • "%variable%" = "%appdata%\­%variable%.exe:*:%variable%"
  • [HKEY_LOCAL_MACHINE\­SYSTEM\­ControlSet001\­Services\­SharedAccess\­Parameters\­FirewallPolicy\­StandardProfile\­AuthorizedApplications\­List]
    • "%variable%" = "%appdata%\­%variable%.exe:*:%variable%"
