Notice of Personal Information Breach

We sincerely apologize to WIZnet Maker members.

On September 27, 2026 (KST), we confirmed that member personal information on WIZnet Maker was exposed through unauthorized access. We immediately blocked access to the website, reported the incident to the relevant Korean authorities, and are strengthening our security.

The information involved includes user ID, name (nickname), email address, password, and login and profile information. For some members, former WIZnet Forum password data (encrypted) or contest application details (name, phone number, address) were also involved. We do not hold national ID numbers or payment information.

We recommend changing your password on any other service where you use the same password. When WIZnet Maker reopens, you will be asked to set a new password.

For questions or to report any damage, please contact secure@wiznet.io.

We apologize again for the concern this has caused.
