Can someone beam an invisible laser into a room from many kilometres away and snoop on conversations taking place inside? As dramatic as it may sound, China has warned government departments and other entities about this new form of laser-based eavesdropping allegedly conducted by foreign spies.&nbsp;According to China's Ministry of State Security, the technology relies on detecting vibrations in glass windows caused by sound waves inside a room.

Can someone beam an invisible laser into a room from many kilometres away and snoop on conversations taking place inside? As dramatic as it may sound, China has warned government departments and other entities about this new form of laser-based eavesdropping allegedly conducted by foreign spies. According to China's Ministry of State Security, the technology relies on detecting vibrations in glass windows caused by sound waves inside a room. It claimed that a spy could potentially reconstruct speech from inside a room by directing an invisible laser beam at a window. Amid heightened fears of foreign espionage and data leaks, the market for counter-surveillance equipment in China is growing. According to the South China Morning Post (SCMP), one of the key devices in demand is a monitoring system capable of detecting and issuing alerts about incoming laser beams, as well as identifying the direction from which the laser originated. Other products include specialised curtains made from electromagnetic-shielding fabric that can block electronic signals, along with devices that can block unidentified Bluetooth and Wi-Fi signals. There is also particular demand for equipment that searches for signals emitted by foreign-made devices. This assumes significance as some Chinese ministries and agencies have banned the use of iPhones at workplaces since 2023 on national security grounds. Since August that year, China has repeatedly warned officials, students and tourists against foreign intelligence operatives. In April 2023, China also amended its counter-espionage law, banning the transfer of documents, data and items related to national security and interests. The sweeping nature of the law is evident from the fact that it does not define what constitutes China's “national security and interests”.
