Today afternoon, I tried to sign in my site as usual, but I cant sign in. So I tried many times, reset my pass, finally I was able to sign in. it's quite strange and i think one possibility is my site has been hacked by some hackers. i received my friend's message just now telling me his site got stolen by a team of hacker with many accounts stolen too, the hackers even are selling his domain. now i can sign in, but i fear i can't sign in again, but when i checked the database, there're quite a lot of data i don't know if they have been moved by hackers or not. my questions are: how i can protect my website? it's a wordpress blog, and has a lot of datas, the domain is in godaddy. How i can protect my website now? my domain, my server, my account? I dont want to lose my website in future. i never thrown so much enegy into one website. Please help me, give me any suggestions!
