Hacker Offers TSMC Employee Data for 3 Bitcoin; Company Confirms Partial Data Leak

November 12 — According to Jiemian News, a hacker has been openly hawking what appears to be personal data of TSMC employees on an underground forum, claiming to hold as many as 46,000 records totaling 6.9GB, asking 3 bitcoin, and even threatening to fully disclose the data if no one buys it within a week. In response, TSMC confirmed that data of some current and former employees was disclosed without authorization. Preliminary findings indicate the data matches information in the systems and services of a certain cloud service provider, but there is currently no evidence that TSMC's own data systems were breached.

TSMC stressed that the data is unrelated to the company's production and customer information. The company has been notifying affected individuals in stages and providing necessary assistance, while working closely with the relevant cloud service provider, investigative authorities and third-party cybersecurity firms to speed up clarification of the cause of the incident and take necessary measures.
