On November 12, 2026, TSMC confirmed that personal data relating to approximately 46,000 current and former employees was compromised through a third-party cloud system. The hackers are offering the 6.9-gigabyte dataset for a starting price of 3 BTC, worth about $220,000, and threaten to publish it if no buyer steps forward within a week. A sample file containing 499 records includes names, national identification numbers, contact details, banking information and emergency contacts. TSMC says its internal systems, production operations and customer data were not compromised, and the company is notifying affected individuals while working with its cloud vendor, law enforcement and external cybersecurity firms.
