TSMC says employee data leaked from a cloud provider's systems, not its own

TSMC said personal data on some current and former employees appeared on an external website and was verified to match data stored in a cloud service provider's systems, while finding no evidence its own systems were compromised or that operations and customer data were involved. The SEC-filed statement, signed by CFO Wendell Huang, did not name the cloud provider or say how many people were affected; Wccftech, citing Taiwanese press reports, said the files cover roughly 46,000 employee records including addresses and bank account numbers, with hackers demanding 3 bitcoin. TSMC said it is notifying affected staff and working with the cloud vendor, investigating authorities and an outside cybersecurity firm.
