Set DNS server to 9.9.9.9, and (known) malware and phishes won’t be able to phone home.
The Global Cyber Alliance (GCA)—an organization founded by law enforcement and research organizations to help reduce cyber-crime—has partnered with IBM and Packet Clearing House to launch a free public Domain Name Service system. That system is intended to block domains associated with botnets, phishing attacks, and other malicious Internet hosts—primarily targeted at organizations that don’t run their own DNS blacklisting and whitelisting services. Called Quad9(after the 9.9.9.9 Internet Protocol address the service has obtained), the service works like any other public DNS server (such as Google’s), except that it won’t return name resolutions for sites that are identified via threat feeds the service aggregates daily.
