Sea Turtle DNS Hijack

in which way are you using the BIG-IP DNS (former GTM) when asking this question?

if it is a DNS resolver for your clients then you don't want to be informed of every IP change on every DNS record, because that just happens when a website changes hosting provider or with DNS load balancing or ...

if it is a DNS server, then you should just use strong passwords and make sure admin access is tightly restricted. those attackers did nothing special, just gain admin access to DNS servers to change records.

and look into implementing DNSSEC.
