My wallet Hacked

Hey every one,
I want to tell you via this post that metamask wallet security is very vulnerable, this morning i have lost all my funds ( 7500 dollars ) that have been transferred to an unknown wallet without me knowing anything about it, there have been no security mistakes from my part, that i am sure.
the problem is that there is no way that i can be refund or to block the hacking wallet.
so every one, you should be very careful using Metamask.
