Smart speakers can be hijacked this way from up to 350 (~107m) feet away. On the other hand, this method can only be done on smartphones from a shorter distance of up to 65 feet (~10m). As for devices, the researchers were able to hijack the iPhone XR, iPad 6, Samsung Galaxy S9, and a slew of smart speakers like the Google Nest. Granted, it takes a lot of setting up, so it’s unlikely someone will go out of their way to hack your device using this method. This may be the silver lining on the entire detail, as this vulnerability is hardware-based, and as such cannot be fixed with any software update. (Source: Light Commands via Engadget)
