I found this on reddit https://www.reddit.com/r/Ripple/comments/bwn09t/gatehub_hacked/ and here as well https://www.xrpchat.com/topic/31759-a-few-user-reported-their-gatehub-wallet-been-hacked-and-xrp-sent-to-r9do2ar8k64nxgld6ojoywaxqhus57ck8k/

So it's not only you, or you wrote this two threads too?

And most repellent part is they don't even give a f*ck for this, there's no single update on their official social media accounts related to this issue.
