- Your home’s online gadgets could be hacked by ultrasound. From New Scientist. This may have happened to you. You idly browse a pair of shoes online one morning, and for the rest of the week, those shoes follow you across the Internet, appearing in adverts across the websites you visit.
But what if those ads could pop out of your browser and hound you across different devices? This is the power of ultrasound technology, says Vasilios Mavroudis at University College London – and it offers a whole new way in for hacking attacks and privacy invasions. He and his colleagues will spell out their concerns at next week’s Black Hat cybersecurity conference in London.
