This is nothing new. Most are aware of the general issues with crypto currency security. Interesting comment from network code maintainer..

We maintain the blockchain, which facilitates the transactions, nothing more... If we had to revert your funds, we would have to convince the entire ecosystem to roll back the blockchain, to prior the block that moved your funds, and every transaction made since along with it... Not only that, it would then be a matter of fight between you and the thief of who got the first transaction out of your wallet...
