To ensure autorun and distribution
Sets the following service settings
- [<HKLM>\System\CurrentControlSet\Services\MsRkNrL] 'Start' = '00000002'
- [<HKLM>\System\CurrentControlSet\Services\MsRkNrL] 'ImagePath' = '<SYSTEM32>\wscript.exe //B "C:\autoexec.vbs"'
Creates the following services
- 'MsRkNrL' <SYSTEM32>\wscript.exe //B "C:\autoexec.vbs"
Malicious functions
Creates and executes the following (exploit)
- '<SYSTEM32>\wscript.exe' //B "%TEMP%\rknrl.vbs"
Executes the following
- '<SYSTEM32>\taskkill.exe' /f /im miner.exe
- '<SYSTEM32>\taskkill.exe' /f /im myminer.exe
- '<SYSTEM32>\taskkill.exe' /f /im myminera.exe
