I've been experiencing little odd situations regarding security. Sometimes suddenly the password start not working so I have to reissue it again. Also, when I access to a WP-Stattraq index page, somehow the option link does not appear, looking like somebody changed the setting to that anybody can access to it.
Just for now I put a .htaccess on the wp-admin and the WP-StartTraq plugin directries and set a password.
It still makes me feel insecure in a way, considering that somebody can possiblly know how to login to the admin areas. Is there any ways to detect/prevent from that somebody else besides me is accessing to the areas?
