Virtual assistants like Siri and Alexa 🤖 make life super convenient, but they could also expose us to sneaky hacks! 😮🔐 Researchers from the University of Michigan and University of Electro-Communications, Tokyo found that a security flaw in device microphones allows hackers to send commands via laser beams! 🔦✨
Here’s the wild part: virtual assistants respond to light waves the same way they do to sound waves! 😱💡 By aiming a laser at the microphone, hackers can trick the device into “hearing” commands—even though human ears pick up nothing. 🎙️🔒 Cybersecurity expert Randy Pargman explains it’s like “speaking over a light beam” that only the mic can detect.
After 7 months of testing, the researchers showed that devices like Google Home, Alexa, and Siri could be manipulated from hundreds of feet away using tools as simple as $14 laser pointers or flashlights. 🕵️♂️💻 A little reminder to stay vigilant in this high-tech world! 🌐✨ factsfun fact

In an astonishing discovery, researchers have figured out how to transform plastic bottles into vanilla flavoring using genetically modified bacteria, as revealed in a 2021 study in Green Chemistry 🧪🔬.
