User Enumeration
The first two user ID’s were tested to determine if user enumeration is possible.

Username Name
ID: 1 admin
ID: 2 romashka
It is recommended to rename the admin user account to reduce the chance of brute force attacks occurring. As this will reduce the chance of automated password attackers gaining access. Take note that if the author archives are enabled it is usually possible to enumerate all users within a WordPress installation.
