1. The user had 1,400 BTC in an old wallet using this software
2. An old version of the software was vulnerable to phishing
3. The user attempted to use the software, and was phished
4. Massive payday for the scammers
Really unfortunate - and goes to show with software you manage yourself you need to be diligent about making sure it's updated. For all the shit coinbase gets, it's difficult to lose your coins in this manner.
