A hacker has offered to sell TSMC employee data for 3 bitcoins, and the company has confirmed that some data was disclosed without authorization.

November 12 - A hacker has publicly offered for sale what appears to be personal data of TSMC employees on an underground forum, claiming to possess up to 46,000 records with a data volume of 6.9GB, and asking for 3 bitcoins, even threatening to fully disclose the relevant data if no one purchases it within a week.

In response, TSMC confirmed today that some current and former employee data has been unauthorizedly disclosed. Preliminary understanding indicates that these data match information from the system services of a certain cloud service provider, but there is currently no evidence showing that TSMC's own data systems have been breached.

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