Please check your account’s password for various web services.

Dear all,

The e-mail address has been used by ID for various web services. As you know, the password leak incident had sometimes been being occurred  by some reasons, such as a service’s security vulnerability, an user’s poor password, an user’s miss operation (including a fishing),  and so on. Especially, if you use same password on some web services, all of their services might be hacked by the password leak.

Fortunately, Mozilla provided “Firefox Monitor” tools for checking password leaked web services out an e-mail address on 25th September, 2018.

Therefore, PLEASE check all your e-mail addresses by this tool.

If the password leak is discovered, please carry out the following operations.

  1. Change the password on the service.
  2. If possible, enable 2-step verification for the account.
  3. Check same password on the important services.
