It's a BGP hijack, whereas I tend to think of a DNS hijack as being a
domain registration hijack. Really, "hijack" is not specific enough that
you can use it by itself and expect people to understand exactly what you
are talking about.
"Spoof" is also way too vague to be meaningful by itself. In this case you
could maybe argue that you're spoofing a BGP route advertisement, but you
don't need to use packet spoofing techniques to generate the malicious DNS
