如何根据目标WiFi的用户信息,用Python生成一份独特的WPA2密码表?

随着无线网络的不断发展,几乎所有场合都会覆盖WIFI信号,无论是公共地点还是家庭之中。众所周知,目前WIFI普遍的认证方式为wpa2,这种认证方式安全性相当不错,但由于人们设置密码时的随意性和固有思维,使得我们可以利用字典暴力破解。普通的字典大多是全覆盖的、总结性的,针对部分弱口令或许有用,不过1g的字典就算跑也要跑几个小时。那么如何利用已知目标wifi用户的信息生成一个不错的字典呢?

寻找wifi及具体信息

首先,生成字典的目的是为了破解密码,而想要破解密码,得先寻找一个wifi,假设找到了你邻居的wifi,那么接下来要做的就是收集信息。譬如:邻居的名字,生日,工作,老婆叫什么,儿子叫什么,生日是哪天。我们获得的信息越多,生成的密码字典就越丰富,破解可能性就越大。

填写信息文件

收集信息后,要做的是创建一个文件。

根据目标用户信息,Python生成WPA2密码字典

如图,首先创建一个名为information的文件,无后缀。格式如下,以“:”为分界线(英文冒号),左侧为信息名称,右侧为信息的具体内容,内容不清楚则填no,由于代码关系,不要少于20行。

生成字典

信息文件创建完毕后,便可以生成字典。这里我使用python来完成这一工作。生成的算法策略如下。

1.  大于8位的直接保留,小于8位的舍弃。

2.  信息相互组合,小于8位舍弃。

3.  生日提取年份、日月与其他信息组合,小于8位舍弃。

4.  所有小于8位的信息与短数字(0-9的全排列)进行组合,生成8位密码。

5.  所有信息与的9位以内短数字进行组合如(1233456789,000000000)。

6.  所有组合与特殊符号相结合,如“#”、“%”等。特殊字符的位置可以是开头中间和结尾。

接下来,使用python根据以上策略对信息进行结合处理。首先将信息存入一个list中。

  f = open('information','r')    lines = f.read().split('/r')    name = lines[0].split(':')[1]    list.append(name)      simple_name = lines[1].split(':')[1]    list.append(simple_name)      family_name = lines[2].split(':')[1]    list.append(family_name)      phone_number = lines[3].split(':')[1]    list.append(phone_number)      study_number = lines[4].split(':')[1]    list.append(study_number)      birthday = lines[5].split(':')[1]    list.append(birthday)      if birthday!='no' and birthday!= 'NO':     birthday_month_day = birthday[4:]     birthday_year = birthday[0:4]     list.append(birthday_month_day)     list.append(birthday_year)    else:     birthday_month_day = 'no'     birthday_year = 'no'     list.append(birthday_month_day)     list.append(birthday_year)      idol_name = lines[6].split(':')[1]    list.append(idol_name)      idol_simple_name = lines[7].split(':')[1]    list.append(idol_simple_name)      father_name = lines[8].split(':')[1]    list.append(family_name)      father_simple_name = lines[9].split(':')[1]    list.append(father_simple_name)      mather_name = lines[10].split(':')[1]    list.append(mather_name)      mather_simple_name = lines[11].split(':')[1]    list.append(mather_simple_name)      son_name = lines[12].split(':')[1]    list.append(son_name)      son_simple_name = lines[13].split(':')[1]    list.append(son_simple_name)      father_birthday = lines[14].split(':')[1]    list.append(father_birthday)      if father_birthday!='no' and father_birthday!= 'NO':     father_birthday_month_day = father_birthday[4:]     father_birthday_year = father_birthday[0:4]     list.append(father_birthday_month_day)     list.append(father_birthday_year)    else:     father_birthday_month_day = 'no'     father_birthday_year = 'no'     list.append(father_birthday_month_day)     list.append(father_birthday_year)      mather_birthday = lines[15].split(':')[1]    list.append(mather_birthday)      if mather_birthday!='no' and mather_birthday!= 'NO':     mather_birthday_month_day = mather_birthday[4:]     mather_birthday_year = mather_birthday[0:4]     list.append(mather_birthday_month_day)     list.append(mather_birthday_year)    else:     mather_birthday_month_day = 'no'     mather_birthday_year = 'no'     list.append(mather_birthday_month_day)     list.append(mather_birthday_year)      son_birthday = lines[16].split(':')[1]    list.append(son_birthday)      if son_birthday !='no' and son_birthday != 'NO':     son_birthday_month_day = son_birthday[4:]     son_birthday_year = son_birthday[0:4]     list.append(son_birthday_month_day)     list.append(son_birthday_year)    else:     son_birthday_month_day = 'no'     son_birthday_year = 'no'     list.append(son_birthday_month_day)     list.append(son_birthday_year)      address = lines[17].split(':')[1]    list.append(address)      university_name = lines[18].split(':')[1]    list.append(university_name)      university_simple_name = lines[19].split(':')[1]    list.append(university_simple_name)          for i in range(20,len(lines)):     list.append(lines[i].split(':')[1])    f.close()

为了阅读方便,information文件中前20个信息写的很具体。最后三行则是对20行之后的补充。

随后,将短数字与特殊符号放入其他两个list中,代码见最后。并根据策略进行相互组合。最后生成符合我们心意的字典。最后附上代码~
