In light of the reports from our users on the 3rd of June, we immediately changed access to all our servers and switched our internal processes to 'under attack mode'. In addition, we are working on a security app update to reduce the chances of potential future attacks. We strongly encourage all our users to keep their wallet apps updated to the latest versions.
Giving lame excuses and what's more, encouraging the users to keep using the same closed source wallet.
If they cared so much about the people, they would have announced that they would be moving towards open source, but not to be.
Anyone who will still trust them is responsible for their loss if the same hack happens again.
