But is that wise? If this malware ends up sending the DNS query
to a legitimate system DNS function, then such a DNS function
will retry the query a number of times to all the DNS resolvers
configured on the client. So you are actually making the problem

Filtering a DNS query on a recursor is almost never the right solution.
