Those examples tunnel traffic over DNS. They do not specifically break large files up into small chunks and exfiltrate them off of a secure network with simple DNS queries.
- cypherpunks01 13y agoSure, yes. All those examples (ozyman, iodine, etc.) tunnel arbitrary traffic over DNS, whereas yours is more traffic-efficient in essentially being a static file server via DNS, I suppose?
- amckenna 13y agoTunneling traffic over DNS is breaking up files (data) into chunks (packets) and exfiltrating off of a network through DNS. Don't get me wrong, it's nice to see a simple example like yours, but projects like http://code.kryo.se/iodine/ http://code.kryo.se/iodine/ do essentially (from an abstract perspective) the same thing.
