• [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Active Setup\Installed Components\{5460C4DF-B266-909E-CB58-E32B79832EB2}]
• StubPath = "%Windir%\InstallDir\Server.exe"

so that Server.exe runs every time Windows starts

• [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run]
• HKLM = "%Windir%\InstallDir\Server.exe"

so that Server.exe runs every time Windows starts

• [HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run]
• HKCU = "%Windir%\InstallDir\Server.exe"

so that Server.exe runs every time Windows starts

• [HKEY_CURRENT_USER\Software\--((Mutex))--]
• ServerStarted = "18/09/2012 19:49:19"
• [HKEY_CURRENT_USER\Software\XtremeRAT]

Other details

• To mark the presence in the system, the following Mutex objects were created:
• --((Mutex))--
• --((Mutex))--PERSIST
• DDrawWindowListMutex
