How has Coinbase handled issues around SMS spoofing? What's to prevent an attacker from impersonating my mobile number and transmit every last bitcoin to themselves?

So in order for someone to drain your account, they would need to spoof an SMS message to Coinbase, intercept a voice call from Coinbase, and know your 6-digit pin. We do this if you try to send, buy, or sell bitcoins.
