AWS MySQL RDS huge CPU spike and rapid storage loss - possible attack?

As you can see from the screenshot attached, we have experienced sudden cpu spike and storage loss. We have nearly lost all storage and had to increase it manually.

When we check database size, it still has the size before this occured, so it seems its not database related. We have checked a lot of stuff (slow logs etc.) but couldn't find the problem.

Is it possible there has been an attack, or any other ideas why this happened and how to recover our free storage?

Thank you.enter image description here
