Yes and...

If you have a really insecure DDNS update mechanism on your master RPZ 
zone, then I can see how RPZ might lower the bar *a little*, but I have 
to stretch my imagination quite a bit for that to happen.

If your ISP doesn't use RPZ (regardless of whether the code is present 
in BIND), then the bad guy has to hack the box, set up an RPZ 
configuration, and then pollute it with bad data.  Much easier to just 
install a bunch of fake zones.

RPZ is a red herring here.
