Hi Bart,
DNS was developed exactly for this kind of purpose.
Storing non-DNS related information for retrieval? As I understand the
proposition (and the original lecture that this idea was based on),
it's was for hiding information in a very small records area of DNS for
propogating information...I don't think the designers for DNS had
spreading AV signatures (or files or other things that have been
proposed, non-Clam related) in mind at the time.
Please be aware of the fact that I don't think that DNS is the correct tool to
distribute files but for distributing something like a serial number it fits
perfectly.
The actual download of the data has to be done outside of the DNS system.
Okay, this would be where my misunderstanding was entering the picture :-) I was thinking DNS would be the distribution engine, not the notification engine.
Sorry for the confusion!
Abusing the DNS to directly transfer files etc is not appropriate as the DNS
infrastructure is not ready for such kind of "abuse".
Give it time...someone's going to do it.
I'm surprised someone hasn't found a hole in DNS that would allow it to act as a way to distribute viruses via DNS records yet...
