When first run, Troj/Banker-EX will drop two files named IESPRT.SYS and LSD_F3.DLL into the Window system folder. These files are detected as Troj/Banker-EX.
Under Windows 9x systems, Troj/Banker-EX will set the following registry entries in order to run automatically on system startup:
HKLM\System\CurrentControlSet\Control\MPRServices\TestService
DllName
lsd_f3.dll
HKLM\System\CurrentControlSet\Control\MPRServices\TestService
EntryPoint
LSD_F3
Under Windows NT based systems (NT, 2000, XP etc.), Troj/Banker-EX will register LSD_F3.DLL under Winlogon Notify and IESPRT.SYS as a driver in order to run them automatically on system startup.
LSD_F3.DLL will have the following settings under Winlogon Notify:
name = f3dsl
path = lsd_f3.dll
notifyfunction = LSD_F3
IESPRT.SYS will have the following driver settings:
drivername = iesprt
displayname = KeIE
imagepath = \??\C:\WINDOWS\System32\iesprt.sys
As a result, the following registry entries will be set:
HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon\Notify\f3dsl
DllName
lsd_f3.dll
HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon\Notify\f3dsl
