Morphology

ultrasecret = secret (transparent) = ultra + secret

The meaning is a straightforward intensification of 'secret' by the productive prefix 'ultra-'.

Etymology

The word ultrasecret starts with the part ultra- ('beyond' or 'extreme'), as in ultraviolet, and ends with secret ('hidden' or 'known by only a few'). So ultrasecret means extremely hidden and known by very few people.
