make sure you change your mysql root passwords!
you do not want to end up like these idiots
Code:
[16:15] <[00|FRA|XP|SP1]-0480> Cracked MYSQL - IP: [196.206.15.57]->[adsl196-57-15-206-196.adsl196-1.iam.net.ma] [USER]: root [PASS]: <null>
[16:22] <[00|FRA|XP|SP1]-0480> Cracked MYSQL - IP: [196.206.20.237]->[adsl196-237-20-206-196.adsl196-1.iam.net.ma] [USER]: root [PASS]: <null>
[16:26] <[00|ESP|2K|SP4]-0151> Cracked MYSQL - IP: [192.168.1.8]->[NO_HOST] [USER]: root [PASS]: <null>

make sure it is not obvious either because i have rooted over 200 linux servers by scanning insecure mysql boxes
