In a statement issued to TechCrunch, a spokesperson for TSMC – who sent emails from a joint press email account and repeatedly declined to give their names – confirmed that a “cybersecurity incident ” at one of the company’s IT hardware suppliers, named Kinmax Technology, resulted in the leak of “information regarding the server’s initial setup and configuration.”

“After review, this incident did not affect TSMC’s business, nor did it compromise any TSMC customer information,” the spokesperson added. “Following the incident, TSMC immediately terminated data exchange with this relevant supplier in accordance with the Company’s standard operating procedures and security protocols.”

TSMC shared a copy of the communication it received from Kinmax Technology, an IT consulting and services organization specializing in networking, cloud computing, storage, security, and database management .

“The morning of June 29, 2023, the Company discovered that our specific internal test environment was hacked and some information was leaked,” Kinmax said in its announcement. “The leaked content mainly consisted of the process of preparing the system installation, which the Company provided to our customers as the default configuration.”

Kinmax added that it “would like to express its sincere apologies to the affected customers,” indicating that TSMC is not the only one of its partners affected by the incident.

Eric Huang, vice president of Kinmax Technology, declined to say how many of its customers were affected.
