The problem is : many time, the default user who is created is : admin, then you can try to crack the password, to stop that, you can use image confirmation or a limit for the connection (for example, only 5 tests). 
 
To know if "admin" is the default user, you can try to go to the login page : http://site.com/wp-login.php and you try ; login : admin, pass : test (or anything else). 
 
if "Wrong password" is printed on the page, the default user is admin, but if there is : "Wrong Username" then it's not the default password ;)
