A senior engineer at Nanya Technology has been indicted in Taiwan for allegedly copying 32 files containing information about the company's DRAM manufacturing process, reports Freedom Times . The engineer was reportedly in talks with Chinese recruitment agencies and allegedly planned to pass Nanya's trade secrets to its next employer in the People's Republic in exchange for higher compensation.
Yeh Yen-wei, a senior engineer in the Advanced Process Development Division at Nanya, joined the company in 2022 and began to communicate with Chinese recruiters in 2025 to explore employment opportunities in the People's Republic. Sometime in mid-February 2026, he submitted his resignation. However, before leaving the company in mid-April, on March 28, April 4, and April 5 — during weekends and either late at night or early in the morning — he visited the company's restricted office areas with his Insta360 X4 Air action camera hidden among snacks to get it past security checks.
Once inside, Yeh used his legitimate account credentials to access Nanya's virtual machines and opened various internal research and development documents. He then used the camera to capture photographs and video of information associated with Nanya's DRAM process technologies and production methods. It goes without saying that he retained the information when he officially resigned from Nanya in mid-April.
However, his actions did not go unnoticed. Nanya's IT security team detected 'abnormal' wireless signals inside the company's restricted facilities (i.e., identified the device using its Bluetooth and/or Wi-Fi signals) and tied them to the employee's access records and activity logs. Eventually, Nanya reported the suspected theft to Taiwanese authorities, which led to an indictment.
