Can you make a DNSBL that contains drones, trojans and other hostile bots?
We could, but we will not, for reasons detailed in the previous question. DNS-based blacklists are very dangerous things. The organization running the list is giving its guarantee that all of the hosts it contains are “bad” in whatever way. It is of utmost importance that the criteria for being listed are well defined. It is preferable if the list is maintained in an automatic fashion to avoid any accusations of people being added or removed for personal reasons. All of that is quite easy with something as clear-cut as insecure proxies. Either a host has an insecure proxy on it, or it does not. If it does then logs of the proxy being (ab)used can be kept to justify the listing. If the host can be shown to no longer have an insecure proxy, the host can be removed. No such procedures can be followed when it comes to trojans, drones, “bad people” and so on. Listings would often be completely arbitrary, and down to the personal judgement of someone.
