SAD DNS is a new form of the DNS cache poisoning attack, a DNS threat neutralized in 2008. SAD DNS leverages novel network side channels that exist in all modern operating systems. The attack opens to an off-path attacker to inject a malicious DNS record into a DNS cache (e.g., in BIND, Unbound, dnsmasq), allowing eavesdropping and tampering of the communication.

The attack was presented for the first time at ACM Conference on Computer and Communications Security (CCS’20) in November 2020 and described in a paper titled "DNS Cache Poisoning Attack Reloaded: Revolutions with Side Channels".
