TSMC staff data goes on sale for 3 BTC for as Taiwan’s supply-chain breaches pile up

The personal data of about 46,000 Taiwan Semiconductor Manufacturing Company (TSMC) staff members has been put up for sale by hackers at auction for around 3 BTC. TSMC clarified that its systems were not compromised in its Thursday confirmation of the data breach. The chipmaker blamed the incident on an outside supplier. Almost 7GB worth of 46,000 TSMC employees’ personal data were put up for sale on the DarkForums and BreachForums underground forums by a seller demanding about NT$7.4 million ($220,000) from interested buyers. The seller opened bidding for one week. If the deadline passes without a deal for the set, they threatened to dump it for free. How did hackers access TSMC staff data?
