I was scammed

I downloaded this extension, bcs i had problem with the Phantom extension, so I was trying to see if it might be problem of the platform. After I opened the extension, it prompted my secret phrase to connect to my account. I did that, everything went well, money was in place. After 15 minutes, I went to check my wallet again, but all my money was gone. The transaction instructions on solscan says withdrawFromNonce, which means that my account address has granted a different address to make transactions on my behalf (I dont even know how to permit this action). The transaction left from solflare, as there is history about the transaction and the history isnt in my phantom account...

Solflare is an open-source app, which means, that anyone can modify the source code and the person approving the updated code can miss something. I checked in my browser history and was always interacting with official site of solflare. You guys do you but I wouldnt recommend it to anybody. 5.5 sol + gone ... cheers guys
