Hackers have posted claims on two dark-web forums about having access to internal TSMC data. The compromised files are 6.9GB in size, and they cover roughly 46,000 employee records. The hackers demand three Bitcoins ($206,000) as ransom for not releasing the details publicly. To prove their claim, they posted a file titled "tsmc.txt" with details about 499 TSMC employees. These details include addresses, bank account numbers and emergency contact details of employees.

Based on the leaked data posted, it looks like a third-party cloud provider was hacked, not TSMC itself.
