To enable easier list maintenance, the format of the Heuristic Security DNS Blocklist has changed to now include “https://“ as a prefix to all entries. This list will continue to be updated monthly or as I received updates.
If you are importing this list into a blacklist enabled firewall such as pfSense, this should not make any difference, but if it does, you can manually edit this prefix out for your firewall.
