DRAM is the working memory inside every phone and PC. A Nanya Technology engineer was indicted for trying to photograph that process know how, and the case was cracked by his camera's wireless signal.
The 360-degree camera made it past the snack pile. The Bluetooth and Wi-Fi radios inside the bag did not.
Nanya Technology, a Taiwan-based DRAM maker, says a senior engineer in its Advanced Process Development Division used an Insta360 X4 Air action camera tucked into a snack pile to pass security into restricted office areas on three weekends this spring. On March 28, April 4, and April 5, 2026, late at night, he used his own credentials to log into company virtual machines and filmed 32 files tied to DRAM process know-how, according to the New Taipei District Prosecutors Office indictment reported by Focus Taiwan.
Nanya's IT security team flagged the abnormal wireless signals inside the restricted area, correlated them with badge access logs, and traced both back to Yeh Yen-wei. The same-day cluster from Liberty Times and CNA carries the same sequence.
Yeh joined Nanya in 2022, began talking to Chinese recruitment agencies in 2025, and resigned in mid-February 2026, prosecutors say. He is charged under Taiwan's Trade Secrets Act for unauthorized reproduction of trade secrets intended for use in mainland China, which carries up to 10 years, and for breach of trust under the Criminal Code. The indictment is not a conviction; proceedings continue.
The recruitment pattern Yeh fits is documented enough to be routine rather than novel. What is new is the detection mechanism: a consumer camera's default-on radios, not a pat-down, is what gave the engineer away.
