The cryptocurrency exchange Altilly (https://altilly.com/) is notifying users they noticed suspicious activities and then lost control of their systems when they migrated to a new hosting provider.

Altilly is unsure if the customer's assets are lost. 

Sounds like there may be some lawsuits if people don’t get their crypto assets back!

“We are investigating what is going on and what has been saved so far.
We are not sure yet if funds are lost.
We are still waiting for final analysis from the current hosting provider.
We will keep you posted.”
