Autostart Technique

This Coinminer registers itself as a system service to ensure its automatic execution at every system startup by adding the following registry entries:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\
services\PAExec
ImagePath = "%SystemRoot%\PaExec.exe -service"

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\
Services\player
ImagePath = "%All Users Profile%\playersclub\LaunchServ.exe"

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\
Services\PAExec
ImagePath = "%SystemRoot%\PaExec.exe -service"

It drops the following file(s) in the Windows User Startup folder to enable its automatic execution at every system startup:

  • %User Startup%\run.bat.lnk

(Note: %User Startup% is the current user's Startup folder, which is usually C:\Windows\Profiles\{user name}\Start Menu\Programs\Startup on Windows 98 and ME, C:\WINNT\Profiles\{user name}\Start Menu\Programs\Startup on Windows NT, C:\Documents and Settings\{User name}\Start Menu\Programs\Startup on Windows 2003(32-bit), XP and 2000(32-bit), or C:\Users\{user name}\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Startup on Windows Vista, 7, 8, 8.1, 2008(64-bit), 2012(64-bit), 10(64-bit).)
