예전에 L0phtcrack 이라는 제품은 윈도우의 패스워드 크랙툴 중 단연 압권의 성능을 가진 제품이었습니다.
취약한 패스워드는 물론 null 패스워드 탐지 , 사전 대입 공격 , 무차별 대입 공격 등을 수행할 수 있는 제품이었습니다.
예전에는 주로 atstake.com 에서 다운 받았는데 , 시만텍에 넘어간 뒤에는 관심이 떨어지고 , 무엇보다 Cain & Abel 같은 녀석이 나오면서 관심에서 사라졌었습니다.
근데 , 인터넷 서핑중에 간만에 발견했는데 버전이 6 더군요.
MD5 Hash: 7ad7197832f670f5b0d9494a4efdb066
SHA1 Hash: 21d568dd2f8200860d41716f843fb052b17c5e21
당연히 공개버전이며 컨설팅용 버전은 구매하셔야 합니다.
전체적으로 보니 UI 가 매우 좋아 졌네요.
