How easy is eavesdropping on network traffic between two computers? Would it be enough to simply cut and split the network cable? Wiretapping is a way to connect to a network cable and start eavesdropping. During eavesdropping, the original communication is "copied" to the attacker's eavesdropping device. The transmitted data is not modified in any way.
And what about the security of home IoT devices? Is the level of their security still as bad? Are the manufacturers spying on their users? We have tested the smart wireless socket Sonoff S26 Wi-Fi for you, which is popular also in Czech online shops.
