Yes I directly copied from the official coinbase app...I have an iphone. I went into coinbase and selected the account I named "Cash Out Account" top right of screen there is a button you hit which pulls up a screen saying only send BTC to this address...
Is it this app:
https://itunes.apple.com/us/app/coinbase-bitcoin-wallet/id886427730 ?
Please verify whether you are using the official application.
As far as I am concerned the 12ngg is from coinbase? As the first transaction made it successfully into my coinbase account
Unfortunately not. The transaction
from 12ngg.. to 36ii5.. made it successfully to coinbase.
This seems to be very odd..
Besides a malicious application which displays attackers addresses (and forwards them if the amount is too low), i can't think of what happened here.
