Square Enix has warned Final Fantasy 14 players of a hacking attempt and suggests everyone with an account change their passwords.
According to the company, it is currently experiencing an attack by a third party attempting to gain access to the Square Enix Account Management System. They are doing this by using a combination of email addresses and passwords possibly obtained from “online services of other companies.”
Square advises against using the same email address and password combination for your Square Enix account as you do for other online services, as it increases the possibility of a third party gaining unauthorized access to your account. That said, you are still at a high risk of your account being accessed should your password contain an easy pattern, sequences of characters, or your DOB.
