简介

Hashcat 自称是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 hash，MD4，MD5，SHA 系列，Unix 加密格式，MySQL 和 Cisco PIX 等。

基本使用

安装

mkdir /pentest && cd $_
wget https://hashcat.net/files/hashcat-6.1.1.7z
7z x hashcat-6.1.1.7z && rm -rf hashcat-6.1.1.7z
cd hashcat-6.1.1 && chmod +x hashcat.bin && cp hashcat.bin hashcat
ln -s /pentest/hashcat-6.1.1/hashcat /usr/sbin/hashcat

• 在使用 GPU 模式进行破解时，可以使用 -O 参数自动进行优化

• 所有的 hash 破解结果都在 hashcat.potfile 文件中

常见参数

-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

攻击模式

以下略

掩码设置

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

掩码案例

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!@-+，就需要用到自定义字符集,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。

--custom-charset1 abcd123456!@-+。  然后就可以用"?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”

更多实验

阿里云按量-抢占式实例-NVIDIA T4-跑 Hashcat

注意点

• 抢占式实例一次只能买1小时,切记1小时

• 实例创建完后需要装对应的 NVIDIA 驱动

• -f 测试的跑分速度很完美,但实际跑的时候速度是达不到的

优点

• 相对便宜,实际用起来一小时不到2元,感觉像在用 vultr

• 性能强

过程

• 付费模式选择 抢占式实例

• 实例类型选择 异构计算 GPU/FPGA/NPU

• 分类选择 GPU 计算型

CPU和内存可以不用考虑,主要是选个好的 GPU,这里可以看到有 NVIDIA T4 和 NVIDIA P4 两种选择

这里选择 T4 便宜一点

镜像选择 Alibaba Cloud Linux 这个兼容 centos,用起来没啥问题

下一步网络选择

建议使用按固定带宽收费,你跑 hashcat 其实用不了多少流量, 带宽峰值 直接拉到 100M

创建完实例后,SSH连接,这里略

安装 hashcat,如果嫌速度慢,可以自己通过 lrzsz 的方式传上去

mkdir /pentest && cd $_
wget https://hashcat.net/files/hashcat-6.1.1.7z
7z x hashcat-6.1.1.7z && rm -rf hashcat-6.1.1.7z
cd hashcat-6.1.1 && chmod +x hashcat.bin && cp hashcat.bin hashcat
ln -s /pentest/hashcat-6.1.1/hashcat /usr/sbin/hashcat

安装显卡驱动

去 NVDIA driver search page 查看支持显卡的驱动最新版本及下载，下载之后是 .run 后缀

安装时一路回车即可,装完之后输入 nvidia-smi

wget https://cn.download.nvidia.com/tesla/450.80.02/NVIDIA-Linux-x86_64-450.80.02.run
sh NVIDIA-Linux-x86_64-450.80.02.run  -no-x-check -no-nouveau-check -no-opengl-files
nvidia-smi

然后就可以愉快的跑 hashcat 了

hashcat -b --force
