This is not new scam though, we have seen a lot of impersonations before, from Elon Musk and other well known crypto personalities. The thing is that probably with that advancement of AI, many are fallen for this trick.
Not saying that the blame should be on the victims here, but how come someone will just trust a supposedly Coinbase staff and give partial of their seed phrase?
Just makes me wonder as we all know that we shouldn't trust, but to verify first? So again, we can't stressed this enough, do not trust anyone even if they say that they are from Coinbase or any other exchanges and asked you for your partial seed phrase.
