> The sellers claim to have about 46,000 records and threatened to publish them if no buyer emerged within a week.

Taiwan Semiconductor Manufacturing Co. (TSMC) confirmed that personal information belonging to current and former employees appeared online, while forum sellers claiming to hold about 46,000 records offered them for 3 Bitcoin (BTC).

The sellers threatened to release the material publicly if they did not find a buyer within a week. Their listings appeared on underground forums including DarkForums and BreachForums.

Samples shown with the offer contained names, national ID numbers and bank account details. These details expose highly sensitive personal and financial information.

TSMC linked the exposed records to an unnamed cloud service provider but did not describe the service. It said it found no evidence that its own systems had been compromised.

Customer information was not affected, the company said. TSMC has notified people whose information was exposed and is investigating with the cloud provider, cybersecurity firms and law enforcement.

The Taiwan-based company is a major chipmaker; it said production-related information was outside the exposure.
