I've found two issue in this app:
The ransomwaredomainblocklist lookup is not correctly populated due to an issue in the python script.
The script ransomwaredomainblocklist.py is removing the first character from each entry due to the below rex in the # rm whitespace block. Looks like it's been re-used from the http list maybe.
ransomwaretrackerdomainorig.write(re.sub(r'^[^h]', '', line))
Replace with the below.
ransomwaretrackerdomainorig.write(re.sub(r'^[^0-9a-zA-Z]', '', line))
List malc0dednsblacklist.csv does not download due to blocking of non standard browsers. My lookup shows the below which comes from cloudflare.
