Why using Wi-Fi at airport or railway station is 'risky'

CERT-in warned public against using public Wi-Fi and suggested VPN (virtual private network) and wired networks instead

When you visit an airport or railway station next time remember that browsing internet using the public Wi-Fi hotspot or wireless internet networks may leave you vulnerable for cyber attacks. 

The government agency Indian Computer Emergency Response Team (CERT-in) has rated the vulnerability quotient of public Wi-Fi in the country at 'high'. It warned public against using public Wi-Fi and suggested VPN (virtual private network) and wired networks instead.

The agency's statement comes after Mathy Vanhoef,
