Side effects:
   • Drops a file
   • Registry modification
   • Makes use of software vulnerability
   • Steals information

 Files It copies itself to the following location:
   • %WINDIR%\mde.exe



The following file is created:

– %SYSDIR%\drivers\oreans32.sys Furthermore it gets executed after it was fully created.

 Registry The following registry keys are added in order to load the service after reboot:

– [HKLM\SYSTEM\CurrentControlSet\Services\oreans32\Security]
   • "Security"=%hex values%

– [HKLM\SYSTEM\CurrentControlSet\Services\oreans32]
   • "Type"=dword:00000001
     "Start"=dword:00000001
     "ErrorControl"=dword:00000001
     "ImagePath"=\??\%SYSDIR%\drivers\oreans32.sys
     "DisplayName"="oreans32"

– [HKLM\SYSTEM\CurrentControlSet\Services\oreans32\Enum]
   • "0"="Root\\LEGACY_OREANS32\\0000"
     "Count"=dword:00000001
     "NextInstance"=dword:00000001



The following registry keys are added:

– [HKLM\SYSTEM\CurrentControlSet\Enum\Root\LEGACY_OREANS32]
   • "NextInstance"=dword:00000001

– [HKLM\SYSTEM\CurrentControlSet\Enum\Root\LEGACY_OREANS32\0000]

It makes use of the following Exploits:
– MS04-007 (ASN.1 Vulnerability)
– MS05-039 (Vulnerability in Plug and Play)
