TSMC's 2nm leak
In early August 2025, TSMC found itself embroiled in an incident where several of its employees reportedly leaked crucial trade secrets regarding its 2nm process.
The leakers were later connected to TSMC supplier Tokyo Electron (TEL), which sparked discussions about cybersecurity in the current age of geopolitical tensions. Taiwanese prosecutors are also involved in this case, citing TSMC's trade secrets as national security.
