TSMC confirmed that data concerning certain current and former employees was disclosed without authorization. A hacker claims to hold more than 46,000 records and threatens to publish them unless paid 3 BTC, or approximately $214,700, within one week. TSMC said there is no evidence that its own security systems were compromised, adding that the data matches records held by a cloud service provider and is unrelated to clients or production. The company is working with cloud service providers and cybersecurity agencies to investigate the incident and prevent similar disclosures. This was not a traditional ransomware attack because no malware was used and TSMC’s systems were not locked out.
