Hashcat是自称世界上最快的密码恢复工具。它在2015年之前拥有专有代码库,但现在作为免费软件发布。适用于Linux,OS X和Windows的版本可以使用基于CPU或基于GPU的变体。支持hashcat的散列算法有Microsoft LM哈希,MD4,MD5,SHA系列,Unix加密格式,MySQL和Cisco PIX等。
hashcat支持多种计算核心:
GPU
CPU
APU
DSP
FPGA
Coprocessor
GPU的驱动要求
AMD GPUs on Linux require "RadeonOpenCompute (ROCm)" Software Platform (1.6.180 or later)
AMD GPUs on Windows require "AMD Radeon Software Crimson Edition" (15.12 or later)
Intel CPUs require "OpenCL Runtime for Intel Core and Intel Xeon Processors" (16.1.1 or later)
Intel GPUs on Linux require "OpenCL 2.0 GPU Driver Package for Linux" (2.0 or later)
Intel GPUs on Windows require "OpenCL Driver for Intel Iris and Intel HD Graphics"
NVIDIA GPUs require "NVIDIA Driver" (367.x or later)

下面使常见的参数,想了解更多的参数可以hashcat --help查看
-a 指定要使用的破解模式,其值参考后面对参数。“-a 0”字典攻击,“-a 1” 组合攻击;“-a 3”掩码攻击。
-m 指定要破解的hash类型,如果不指定类型,则默认是MD5
-o 指定破解成功后的hash及所对应的明文密码的存放位置,可以用它把破解成功的hash写到指定的文件中
--force 忽略破解过程中的警告信息,跑单条hash可能需要加上此选项
--show 显示已经破解的hash及该hash所对应的明文
--increment 启用增量破解模式,你可以利用此模式让hashcat在指定的密码长度范围内执行破解过程
--increment-min 密码最小长度,后面直接等于一个整数即可,配置increment模式一起使用
--increment-max 密码最大长度,同上
--outfile-format 指定破解结果的输出格式id,默认是3
--username 忽略hash文件中的指定的用户名,在破解linux系统用户密码hash可能会用到
--remove 删除已被破解成功的hash
-r 使用自定义破解规则

这里列一下常见的掩码字符集
l | abcdefghijklmnopqrstuvwxyz 纯小写字母
u | ABCDEFGHIJKLMNOPQRSTUVWXYZ 纯大写字母
d | 0123456789 纯数字
h | 0123456789abcdef 常见小写子目录和数字
H | 0123456789ABCDEF 常见大写字母和数字
s | !"#$%&'()*+,-./:;<=>?@[\]^_`{|}~ 特殊字符
a | ?l?u?d?s 键盘上所有可见的字符
b | 0x00 - 0xff 可能是用来匹配像空格这种密码的
下面举几个简单的例子来了解一下掩码的设置
八位数字密码:?d?d?d?d?d?d?d?d
八位未知密码:?a?a?a?a?a?a?a?a
前四位为大写字母,后面四位为数字:?u?u?u?u?d?d?d?d
前四位为数字或者是小写字母,后四位为大写字母或者数字:?h?h?h?h?H?H?H?H
前三个字符未知,中间为admin,后三位未知:?a?a?aadmin?a?a?a
6-8位数字密码:--increment --increment-min 6 --increment-max 8 ?l?l?l?l?l?l?l?l
6-8位数字+小写字母密码:--increment --increment-min 6 --increment-max 8 ?h?h?h?h?h?h?h?h
如果我们想设置字符集为:abcd123456!@-+,那该怎么做呢。这就需要用到自定义字符集这个参数了,hashcat支持用户最多定义4组字符集
--custom-charset1 [chars]等价于 -1
--custom-charset2 [chars]等价于 -2
--custom-charset3 [chars]等价于 -3
--custom-charset4 [chars]等价于 -4
在掩码中用?1、?2、?3、?4来表示。
再来举几个例子
--custom-charset1 abcd123456!@-+。然后我们就可以用"?1"去表示这个字符集了
--custom-charset2 ?l?d,这里和?2就等价于?h
-1 ?d?l?u,?1就表示数字+小写字母+大写字母
-3 abcdef -4 123456 那么?3?3?3?3?4?4?4?4就表示为前四位可能是“abcdef”,后四位可能是“123456”

首先先把我们的握手包转化为hccapx格式,现在最新版的hashcat只支持hccapx格式了,以前的hccap格式已经不支持了

1.首先走一遍常用的弱口令字典
2.组合密码,如:zhang1999,用姓氏和出生年组合,当然也可以用其它的组合,这里举个例子而已
3.把常用的掩码组合整理起来放在masks中的.hcmask文件中,然后让它自动加载破解
4.如果实在不行,你可以尝试低位数的所有组合去跑,不过不建议太高位数的组合去破解,因为如果对方设置的密码很复杂的话,到头来你密码没有破解到,却浪费了大量的时间和资源,得不偿失
--gpu-accel 160 可以让GPU发挥最大性能。
--gpu-loops 1024 可以让GPU发挥最大性能。
--segment-size 512 可以提高大字典破解的速度。
