Arrival Details

This Trojan arrives on a system as a file dropped by other malware or as a file downloaded unknowingly by users when visiting malicious sites.

Installation

This Trojan drops the following files:

  • %Application Data%\Microsoft\Windows\Recent\CustomDestinations\{Random}.temp
  • %Application Data%\Microsoft\Windows\Recent\CustomDestinations\{Random}.customDestinations-ms~{Random}.TMP
  • %Application Data%\Kollegiebyggerier.Pau
  • % Internet Files%\Content.IE5\{Random}\json[1].gp
  • %Application Data%\lamourtesy.dat

(Note: %Application Data% is the current user's Application Data folder, which is usually C:\Documents and Settings\{user name}\Application Data on Windows 2000(32-bit), XP, and Server 2003(32-bit), or C:\Users\{user name}\AppData\Roaming on Windows Vista, 7, 8, 8.1, 2008(64-bit), 2012(64-bit) and 10(64-bit).)

It adds the following processes:

  • powershell.exe -windowstyle hidden {Obfuscated Powershell Command}
  • %System%\msiexec.exe
  • %System%\cmd.exe /c REG ADD "HKCU\Software\Microsoft\Windows\CurrentVersion\Run" /f /v "Counterreplying83" /t REG_EXPAND_SZ /d "%Lunaria% -windowstyle 1 $Trykkammerets=(gi 'HKCU:\Software\Komprimeringerne\').GetValue('Missionshotellet');%Lunaria% ($Trykkammerets)"

(Note: %System% is the Windows system folder, where it usually is C:\Windows\System32 on all Windows operating system versions.)

Autostart Technique

This Trojan adds the following registry entries to enable its automatic execution at every system startup:

HKEY_CURRENT_USER\Software\Microsoft\
Windows\CurrentVersion\Run
Counterreplying83 = %Lunaria% -windowstyle 1 $Trykkammerets=(gi 'HKEY_CURRENT_USER:\Software\Komprimeringerne\').GetValue('Missionshotellet');%Lunaria% ($Trykkammerets)
