Why would the "victim" care (or even find out about) this "attack"? My understanding is that because eth is fungible, it would poison an existing wallet with funds in it. I.e. if you have $5 in coins, and I give you $5 more in stolen coins, your entire coinpurse is essentially tainted. Your example would just be giving somebody a tainted wallet. Worst case scenario, you cycle your keys.
