More Than 46,000 TSMC Employees' Personal Records Offered for Sale Online
Hacker Claims to Have Obtained Emergency Contact Details Along with Other Personal Information
TSMC Acknowledges Personal Data Leak
Personal information belonging to more than 46,000 current and former employees of Taiwan's TSMC, the world's largest foundry, has been leaked.
According to local media, including the United Daily News, a post recently appeared on the hacking forums DarkForums and BreachForums offering 6.9 gigabytes (GB) of TSMC employee data for three bitcoins, worth about KRW 280 million.
The hacker claimed to have information in 19 categories, including employees' names, dates of birth, job titles, nationalities, identification numbers, addresses, mobile phone numbers, email addresses and banking information, as well as emergency contact details. The hacker said all the data would be released if no buyer came forward within a week.
The authenticity of the more than 46,000 records has not yet been verified. However, TSMC said on November 12 that it had confirmed some current and former employees' information was posted on an external website without authorization.
TSMC said, "There is currently no evidence that our information systems were hacked," adding that "the leaked information matches data in the systems of a cloud service provider."
TSMC is working with the cloud service provider and cybersecurity agencies to investigate the cause, scale and route of the leak and take follow-up measures.
