I saw it today, i was impressed about this but when i started to introduce myself in why ethereum has been hacked today i realized that it has been hacked a lot of times in the past, and a lot of ico's lost a lot of money because of ethereum insecurity. It is not fair, not even for the ethereum's holders and for those ico's who had balance on those multisignature wallets.
I hope that ethereum is not going to be hacked again.. but it seems like if it is one of the less-secure altcoins at the moment.
