Connected devices are ubiquitous in our era of wireless chips heavily relying on streaming data to someone elseβs servers. This sentence might already start to sound dodgy, and it doesnβt get better when you think about todayβs smart glasses, like the ones built by Meta (aka Facebook).
[sh4d0wm45k] doesnβt shy away from fighting fire with fire, and shows you how to build a wireless device detecting Metaβs smart glasses β or any other companyβs Bluetooth devices, really, as long as you can match them by the beginning of the Bluetooth MAC address.
[sh4d0wm45k]βs device is a mini light-up sign saying βGLASSHOLEβ, that turns bright white as soon as a pair of Meta glasses is detected in the vicinity. Under the hood, a commonly found ESP32 devboard suffices for the task, coupled to two lines of white LEDs on a custom PCB. The code is super simple, sifting through packets flying through the air, and lets you easily contribute with your own OUIs (Organizationally Unique Identifier, first three bytes of a MAC address). It wouldnβt be hard to add such a feature to any device of your own with Arduino code under its hood, or to rewrite it to fit a platform of your choice.
Weβve been talking about smart glasses ever since Google Glass, but recently, with Metaβs offerings, the smart glasses debate has reignited. Due to inherent anti-social aspects of the technology, we can see whatβd motivate one to build such a hack. Perhaps, the next thing weβll see is some sort of spoofed packets shutting off the glasses, making them temporarily inoperable in your presence in a similar way weβve seen with spamming proximity pairing packets onto iPhones.
