As I read I'm not the first and only one that got robbed on Kraken - the same thing happened to this user also:

***
“On Kraken this morning I had a bunch of emails show up with changes to my 2 factor, and then a series of withdrawals. None of these changes were made by me! I had USD in the account which was used to buy BTC and all the BTC was withdrawn. I did not do any of this. I have opened a ticket with kraken support as soon as I found out but no response yet.

Is anyone else seeing this happen to them??

Posted this on behalf of my brother /u/ds720 since he couldn't post on this subreddit. Expect replies from him.”
