압축 파일의 패스워드 찾기

root@bt:~/Desktop# vi unzip.py

import zipfile
zFile = zipfile.ZipFile('evil.zip')            zip된 파일 열기
passFile = open('dictionary.txt')        dictionary 파일 열기
for line in passFile.readlines():
        password = line.strip('\n')
        try:
                zFile.extractall(pwd=password)        사전에서 가지고 온 패스워드를 인자로 전달
                print '[+] Password = ' + password + '\n'
                exit(0)
        except Exception, e:
                pass

root@bt:~/Desktop# python unzip.py
[+] Password = secret

함수를 가지고 모듈화 해보기

import zipfile
zFile = zipfile.ZipFile('evil.zip')
passFile = open('dictionary.txt')
for line in passFile.readlines():
        password = line.strip('\n')
        try:
                zFile.extractall(pwd=password)
                print '[+] Password = ' + password + '\n'
                exit(0)
        except Exception, e:
                pass

쓰레드 사용해 보기

import zipfile
from threading import Thread

def extractFile(zFile, password):
        try:
                zFile.extractall(pwd=password)
                print '[+] Found password ' + password +'\n'
        except:
                pass
def main():
        zFile = zipfile.ZipFile('evil.zip')
        passFile = open('dictionary.txt')
        for line in passFile.readlines():
                password = line.strip('\n')
                t = Thread(target=extractFile, args=(zFile, password))
                t.start()

if __name__ == '__main__':
        main()

크랙할 압축 파일의 이름과 크랙에 사용할 딕셔너리 파일의 이름을 사용자가 직접 정의한다.

optparse 라이브러리를 임포드한다.

        try:
                zFile.extractall(pwd=password)
                print '[+] Found password ' + password + '\n'
        except:
                pass
def main():
        parser = optparse.OptionParser('usage%prog '+\
        '-f <zipfile> -d <dictionary>')
        parser.add_option('-f', dest='zname', type='string',\
        help='specify zip file')
        parser.add_option('-d', dest='dname', type='string',\
        help='specify dictionary file')
        (options, args) = parser.parse_args()
        if(options.zname == None) | (options.dname == None):
                print parser.usage
                exit(0)
        else:
