I made quantum-dns available in my github.
Its simple to use (non-recursive) DNS server for
IPv4 and IPv6 and also works without having an
IP address assigned to the interface (i.e. it can
answer any DNS query).
Similar to my writeup on QUANTUMINSERT it also contains
a demo FoxAcid script for HTTP. Theoretically it'd also quite easy to make STARTTLS disappear with quantum-dns if its not
enforced on the sender side. While with QUANTUMINSERT
you need to see the TCP sequence# and port, with DNS you
need the XID and port, so it makes entirely sense to
have good passive capabilities for e.g. 3G/4G.
A monitor port on a large peering point is enough capability though.
Thats a sample run from my lab (please forgive me :)
And yes thats trivially to implement, but so is
QUANTUMINSERT which is so easy that I never considered it
an attacking scenario either. It was fun to code though
to get hands on DNS again. For DNSSEC support, you need
to purchase special license. :)
