Lessons learned:
2FA using SMS is badly compromised.
You can't outsource your computer/cryptocurrency security to a 3rd party like your phone carrier. It's a recipe for disaster.
Hackers are targeting prominent bitcoiners - but it's only a matter of time for the rest of us.
Thieves are impersonating prominent bitcoiners, asking friends for "loans" of BTC (etc) - which just means more victims.
It's not just bitcoins - bank accounts and everything else are vulnerable. (And you can't fix those with a Trezor or paper wallet.)

What else?

That is a serious problem which bitcoiners are facing. I have many friends whose validated wallets have been penetrated by hackers and withdrawn all of their balance to other wallet address. The only solution for the meantime was to make dummy accounts. Multiple dummy accounts increases your protection from hacking while your official validated wallet must not have zero balance always and must only be used during cashout.
