TSMC confirms hacker obtained employee data and demanded 3 BTC
The breach, involving a 6.9 GB database of 46,000 staff records, is linked to a third‑party cloud provider rather than TSMC’s own network, and the chipmaker says production and customer data are unaffected.
Key takeaways
- 1Hacker posted a 6.9 GB file containing 46,000 employee records on an underground forum
- 2TSMC demanded 3 BTC (approximately $120,000) for the stolen data
- 3Preliminary investigation links the leak to a third‑party cloud service, not TSMC’s own systems
TSMC said on 12 November 2026 that a hacker had obtained a database of employee information and was seeking 3 BTC in exchange for it. The demand was posted on an underground forum that specialises in illicit data sales.
The leaked file totals 6.9 GB and contains personal details of roughly 46,000 current and former employees, according to the chipmaker’s statement. TSMC said the hacker’s offer was made publicly on the forum, where the data was described as an employee database.
TSMC stressed that its internal IT infrastructure was not breached. The company said production lines and customer designs remain fully operational and no client data has been accessed. It added that the incident does not affect the supply of chips to its customers.
The firm is notifying all affected staff and is working with the cloud service provider that hosted the compromised data, law‑enforcement agencies and external cybersecurity firms to investigate the breach. TSMC said it will take remedial steps with the vendor to prevent further exposure.
Data breaches in the semiconductor sector have risen as attackers target high‑value intellectual property and employee information. While the exposure does not threaten TSMC’s manufacturing output, it raises concerns about personal‑data security for a large workforce.
