상세설명

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.
