This personal page has been hacked. I have restored the last backup but I lost a lot of things. I am trying to recover them one by one. Unfortunately, my latest posts are gone forever :(.
Probably this is the work of a script kiddie that enjoys exploiting a WordPress vulnerability or similar. I really don’t understand the purpose of this. A game for him, a lot of hours lost for me. But not everything is negative, I learnt something: work on your site security, even if it is just a personal page.
There is no perfect security, but I have to make them harder. My fault.
