Researchers at Indiana University have warned of the increased opportunity for hackers resulting from the spread of Wi-Fi. The researchers were specifically talking about the new breed of city-wide Wi-Fi networks where thousands can be logged on simultaneously, but the principle can also be applied to smaller-scale public hotspots.
What’s more, the researchers think such a threat could piggyback across multiple Wi-Fi networks too, taking over thousands of networks in one fell swoop. The researchers think such an attack would easily spread by guessing admin passwords that simply haven’t been changed. In fact, they estimate that 36 per cent of passwords could be guessed.
