Posted on 2026-11-12 18:10:13
TSMC says there is no evidence its internal systems were hacked after information belonging to some current and former employees appeared on an external website without authorization.
The company says the exposed information matches data held by a cloud service provider and does not include manufacturing or information related to customers.
The statement follows media reports that a hacker was offering employee information for sale on an underground forum, claiming to have obtained 46-thousand records totaling 6.9 gigabytes.
The seller reportedly demanded three Bitcoin and threatened to release all the information if no buyer came forward within a week.
TSMC says it's notifying affected employees and working with the cloud service provider, investigators and cybersecurity specialists to determine what happened.
