※ 상세 설명

네트워크 공유 폴더와, 윈도우 보안패치 헛점등을 이용해서 전파및 설치된다. Backdoor 가 실행 되면, 일반적으로 윈도우 시스템 폴더 (win9x: C:\Windows\system, win XP: C:\Windows\system32, win2000, NT : C:\WinNT\system32) 에 smss.pif(184,832 Bytes) 파일이 설치된다. 이때 해당 파일이 동작하게 되면 자신을 다음과 같이 레지스트리에 등록되어 다음 부팅시 실행되도록 조작 한다. HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run 항목에 Microsoftf smss Control = smss.pif HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\RunServices 항목에 Microsoftf smss Control = smss.pif HKEY_CURRENT_USER\Software\Microsoft\OLE 항목에 Microsoftf smss Control = smss.pif 을 생성한다. 그리고 다음 처럼 레지스트리를 수정 한다. HKEY_LOCAL_MACHINE\Software\Microsoft\OLE 항목에 EnableDCOM = N ("Y"가 정상) HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\LSA Restrictanonymous = dword:00000001 다음과 같은 정보를 이용하여 시스템 권한 얻기를 시도 한다.
