Nanya engineer caught stealing DRAM trade secrets via hidden camera detected by its wireless signals
↗
A senior Nanya Technology engineer was indicted for attempting to steal DRAM process technology using a 360-degree camera hidden in snacks, but was caught when IT security detected the device's wireless emissions and correlated them with his access logs.
This case demonstrates that wireless signal monitoring in restricted areas can catch insider threats even when physical concealment bypasses visual inspections. It also highlights the ongoing risk of trade secret exfiltration in semiconductor manufacturing, where employees with legitimate access can copy sensitive data before departing for rival firms.

Yeh Yen-wei used an Insta360 X4 Air camera concealed in snacks to photograph 32 files containing DRAM process information during off-hours visits to restricted areas.
Nanya's IT security team detected the camera through its Bluetooth and/or Wi-Fi signals and tied the device to Yeh by correlating those emissions with his access records and activity logs.
Yeh was indicted under Taiwan's Trade Secrets Act and faces up to 10 years in prison, though forensic examination found no evidence the stolen data was successfully transmitted outside the company.
