A new report indicates that Nintendo appears to have been the victim of a cyberattack. The security breach reportedly targeted TINYpulse systems, which are "associated with employee engagement and workplace feedback functions."

According to the report, the hacker known by the pseudonym SHADOWBYT3$ allegedly retrieved approximately 859 MB of data as of June 13, 2026. This private information reportedly pertains solely to Nintendo employees. It is said to include names, email addresses, employee surveys, bank statements, forms, reports, and comments regarding the workplace.

The breach combines "sensitive personal and financial details, such as bank statements and W-9 tax forms, with internal workplace analytics".

It should be noted that the hack has yet to be verified.
