No team, small wallpaper, doesn't look legit.
Unfortunately many scammers are jumping on the DeFi train nowadays, and offer projects which are a direct copy of the current successful projects.
DYOR but to me this looks shady as hell
That's correct. However, does the size of the whitepaper really matter?
I think the major point of any project should be in delivering and fufiling whatever it is that was promised in their whitepaper and not whether the WP is long or small.
