Effects 

XPCSpy is a PUP (Potentially Unwanted Program) that carries out the following actions:

• It logs the keystrokes typed by the user.
• This way, it can obtain the passwords that have been entered in the computer.
• It captures screenshots.
• It can record these actions:
  - the accessed websites.
  - the opened windows.
  - the email messages, chat conversations and instant messages.
  - the programs that have been run.
• It has rootkit functionalities in order to hide its processes and make its detection more difficult.

Infection strategy 

XPCSpy creates and hides the subfolder XSOFT in the Program Files directory with the following files:

• SMSS.EXE, which is the main component.
• AMON.DLL, IMON.DLL and KEYMON.DLL.
• SYSRTS.EXE.
• RSRSYS.SYS, which belongs to the rootkit it uses to hide its own processes.
  All these files are created in the subfolder XWORKING located in the subfolder XSOFT of the Program Files directory.
• RX.EXE. This file is also copied as XLD.EXE.

XPCSpy creates the following entries in the Windows Registry:

• HKEY_LOCAL_MACHINE\ SYSTEM\ ControlSet001\ Services\ SystemLoginService
  ImagePath = C:\Program Files\XSoft\xworking\sysrts.exe
• HKEY_LOCAL_MACHINE\ SYSTEM\ CurrentControlSet\ Services\ SystemLoginService
  ImagePath = C:\Program Files\XSoft\xworking\sysrts.exe
  By creating these entries, XPCSpy registers itself as a system service.
• HKEY_CLASSES_ROOT\ CLSID\ {3A9DB4A6-E29C-4AE8-9C44-B058941EB5D0}\ InprocServer32
  (Default) = C:\Program Files\XSoft\xworking\IMon.dll
• HKEY_CLASSES_ROOT\ CLSID\ {67C4682D-5AED-48DB-83CB-2B53270E9BCB}\ InprocServer32
  (Default) = C:\Program Files\XSoft\xworking\AMon.dll
  By creating these entries, XPCSpy loads the files IMON.DLL and AMON.DLL, so that they can carry out their actions.

  (Default) = {67C4682D-5AED-48DB-83CB-2B53270E9BCB}
