Dynamic DNS resolution: Fast flux (5a99f82a-48c8-5f89-836f-78901e764677)
Dynamic DNS resolution: Fast flux (as obfuscation technique) - Adversaries may use Fast Flux DNS to hide a command and control channel behind an array of rapidly changing IP addresses linked to a single domain resolution. This technique uses a fully qualified domain name with multiple IP addresses assigned to it which are swapped with high frequency using a combination of round robin IP addressing and short Time-To-Live (TTL) for a DNS resource record.
