Wi-Fi signals turn phones into spying devices
Recent reports reveal that Wi-Fi signals are no longer used solely for internet connectivity; they have become potential tools for covert surveillance and user tracking. When a phone connects to the network, it emits signals containing precise data that can be used to create a "wireless fingerprint," enabling the differentiation of devices and linking them to specific behaviors and locations—especially in crowded places like airports and markets. The danger lies in the fact that such surveillance does not require access to message or call content; merely data about the presence of devices is enough to build a comprehensive behavioral profile, underscoring the need to establish legal and ethical regulations to protect digital privacy.
