Statement Regarding the Unauthorized Access of Employee Personal Data
TSMC has found that some of our current and former employee data was made available on an external website without authorization. Currently, we have found no evidence that TSMC’s systems have been compromised. This information has been verified to match data stored in the system services of a cloud service provider, but is unrelated to the company’s operations or customer-related data. We have been informing impacted personnel and are providing them with necessary support. TSMC has engaged with both the cloud service vendor, the relevant investigating authorities, and a third-party cybersecurity agency to jointly ascertain the facts and take necessary actions. We remain firmly committed to protecting employee privacy and safeguarding data security.
