Close your server.

With some brute force attack is possible break passwords and your server will be fucked

I recommend you set strong password, database permissions properly and will be fine

Don't use "root" as username and maybe not "1234" as password..

And besides that forbid remote mysql database usage..

[Micr0]

change you User name on mysql a program mysql brute need only ip / user name to decode you password you use default user name "Root" and verry easy to decode you password "Don't Use >Root< User Name"

Limit network access to database server, to be allowed only by your homepage server and your home PC. You can do that within MySQL table "user" (database mysql). Additionally add firewall rules to block all incomming connections on port 3306 (except for connections from your home page server IP, game/login server IP, and eg. your home PC IP). Also check your homepage code for eg. mysql injection vulnerability (thats probably most likely the source of "hacks")

Personally I wouldn't graduate the most guys that high as the most guys try the simplest things ever and that is bruteforcing.

[Szponiasty]

Bruteforcing is of no use, when server actively rejects network connections from IP's out of "allowed" list

Agreed, but Starter meant that "15yo hackers" try the simplest way, like bruteforce
