Okay, whole upload dir deleted. Still: to bring a malicious hidden php code in e.g. .jpg extension would mean there has to be code added to wp core files, right? It’s a clean install with changed keys, mysql, wp admin and even ftp wps. Also checked mysql wp_users: just admin. Searched for suspicious code in mysql. No edoced. What happened?
