While highly unlikely, that's of course possible. That's the
bootstrapping problem. In order to ensure that you have a legitimate
install disk, you would need to create/receive it from a safe source
(e.g. if your computer is compromise, you might not even be downloading
it from the actual site!)
You could buy a new computer that came with Debian preinstalled
(assuming you trust the manufacturer and seller), or you could ask a
local user group to provide an installer for you (if you trust them to
give you a safe medium)... you will need to trust someone/something.

Once you have a trusted host, it can be used for ensuring further
updates can be trusted.
