The website was hacked multiple times. While I was trying to prevent it
happen again :
- I did upgrade to latest version
- changed passwords
- made fresh wordpress install, imported RSS feed of old instance
and disabled all plugins I don't use.
..and it was hacked again.
I did now checked access.logs files with grep and all what I could find
suspicious is :
access.log:69.163.128.12 - - [31/Oct/2010:03:05:04 -0700] "POST
/wp-cron.php?doing_wp_cron HTTP/1.0" 200 184 "-" "WordPress/3.0.1; "
access.log.2010-10-29:64.0.55.44 - - [29/Oct/2010:13:39:27 -0700] "POST
/wp-admin/includes/planb.php HTTP/1.1" 200 8194 "
http://blog.numbeo.com/wp-admin/includes/planb.php" "Mozilla/5.0 (Windows;

This planb.php looks fishy with it's content :
<?PHP

$login = "";
$pass = "";
$md5_pass = "";

I did remove it. I did add security at wordpress.org to this thread.
Comments appreciated.
