A list of domains that are known to be used to propagate malware are listed in Bind and Windows zone files. The domains are loaded onto an internal DNS server. When a computer requests a URL or file from one of these domains, a fake reply is sent, thus preventing many malware installs from occuring.
Dead-Hosts is the replacement of the original idea behind funilrys/dead-hosts. Indeed, the idea was to test - with the help of PyFunceble and Travis CI - hosts file, list of domains or even bocklist to have a list of only active domains or IP.
Today, we provide our infrastructure for anybody who want it. Just ask!
PyFunceble is the tool that our infrastructure use to get the status (ACTIVE, INVALID, INACTIVE) of a given domain or IPv4.
