TSMC confirmed that a personal data leak affected current and former employees of the Taiwanese semiconductor manufacturer. Anonymous sellers on DarkForums and BreachForums offered around 46,000 records for 3 bitcoin and threatened to publish the data if no buyer came forward within a week. Samples contained names, national identification numbers and bank account details, but TSMC said customer information and production-related data were not affected. According to the company, the exposed records were linked to a cloud service provider, which it did not identify, and no breach of its own systems had been established. Affected individuals were notified, and TSMC is investigating the origin of the leak with the provider, cybersecurity firms and law enforcement.
