what if evil guys hack my mom ISP DNS servers and use RPZ to redirect traffic from mom_bank.com to evil.com?

How can she detect this?

Thankfully mom_bank.com is not valid, as underscores aren't valid in dns names :)

Additionally, SSL certificates combined with DNSSEC/DANE can provide some protection.  Some of this technology may 
not be available today, but is worth tracking if you are interested in this topic.
