- Windows Task Manager (Taskmgr)
- Registry Editor (RegEdit)
blocks the following features:
- System Restore (SR)
Creates and executes the following:
- '%APPDATA%\Microsoft\Credentials\Breaker_World.exe'
- '%APPDATA%\Microsoft\Credentials\wincom.exe'
Executes the following:
- '<SYSTEM32>\reg.exe' export HKLM\SOFTWARE\Microsoft\Windows" "NT\CurrentVersion\SystemRestore <SYSTEM32>\wbem\srestor.exe
- '<SYSTEM32>\reg.exe' delete HKLM\SOFTWARE\Microsoft\Windows" "NT\CurrentVersion\SystemRestore /f
- '%WINDIR%\explorer.exe' <Current directory>
Modifies settings of Windows Explorer:
- [<HKCU>\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer] 'DisallowRun' = '00000001'
