A hacker is selling TSMC employee data on an underground forum for 3 Bitcoin.

The seller claims to have 46,000 employee records totaling 6.9 GB, and has threatened to release everything publicly if no one buys it within a week.

Tonight, Bitcoin is worth about $72,860 each, making 3 Bitcoin worth around $219,000.

That’s about NT$7.19 million, or roughly NT$156 per record on average.

TSMC responded today, confirming that data belonging to some current and former employees had been posted on an external website. However, there is currently no evidence that the company’s systems were breached.

TSMC said the data matches information in the systems of a cloud service provider, and is unrelated to production or customer data.

The company has notified affected employees and is working with the cloud provider, investigative authorities, and external cybersecurity organizations to investigate.

It has not yet been confirmed how many of the 46,000 records contain valid data.

If you are a current or former TSMC employee and receive a message claiming to be from the company, a colleague, or a vendor asking you to provide your account details, password, or verification code, please verify the sender’s identity through official company channels first.

TSMC’s response did not identify the cloud service provider or specify what fields were included in the leaked data.
