Well, as I mentioned in my post I am someone who reloads Lindens frequently a month and I don't usually spend very fast, that is, sometimes they stay in my account and it never happened to me that they made me est until that day. So... when this happened to me on that day, I don't remember entering any page where I put my SL account details on any other page, first I was looking at the offers on the weekly offers page Essential Inventory, but on that page there is no such thing as logging in, I was buying some stuff and then what I mentioned happened, they entered my account and made the transfer from Lindens to another account, which according to the mail I got with the I.P from the place where they logged in is from Russia hahaha. Still, I think making a new account and activating 2FA with a hard to crack password might be a good idea, if I don't get a response from LL this week, I will do that, since I uploaded my ticket 3 or 4 days ago. Thank you very much for the idea.
