Chipmaking giant TSMC discovers major employee data leak—reports say info was up for sale for three bitcoin on shady forums

TSMC says unauthorised data containing records of current and former employees was posted on an external website. The chipmaker says it has found no evidence that its own systems were compromised, and says the incident did not involve company operations or customer information.

Seeking Alpha reports that the leak involves more than 46,000 employee records. Taiwanese media reports that hackers offered 6.9 GB of data for three bitcoin, with a sample said to include national ID numbers, addresses and banking details. TSMC says it has notified affected employees and is investigating with its cloud service provider, authorities and a cybersecurity firm.
