What happened
TSMC says the exposed employee records were tied to an unnamed cloud service provider, not its own infrastructure, and that affected staff have been notified. Sellers on DarkForums and BreachForums asked for 3 BTC for roughly 46,000 records, with a one-week deadline before public release; Business Next reported samples containing names, national ID numbers and bank account details. The incident sits alongside Bithumb's October intrusion into an internal tool, Daishin Securities' leak of 38,000+ customer records, a Mirae Asset Global Investment case, and Coinbase's exposure via Amplitude; South Korea's Financial Supervisory Service is investigating and has sent an on-site team to Daishin. Watch whether the one-week deadline passes with publication and whether the provider is named.
