Lukasz found that the light that is gloriously eminating from a monitor can be picked up by the ambient light sensors in a mobile device. If an end user takes a leisurely stroll to a malicious domain, an attacker can determine their browser history.

These sites produce small variations in light that are detected by the ambient light sensors. This attack method can also steal a precise QR code.
