Airport Railway Stations free WI-FI unsafe: Government agency Indian Computer Emergency Response Team (CERT-in) has warned that browsing on free WIFI at airports and railway stations may make you a victim of Cyber attack. “Successful exploitation of these vulnerabilities allows an attacker to obtain sensitive information such as credit card numbers, passwords, chat messages, emails etc,” CERT-in said. The nodal agency for responding to computer security incidents in India has rated the vulnerability quotient of public WI-FI in the country at ‘high’.The Indian agency has given instructions that users should avoid public Wi-Fi at all costs and instead use VPN (virtual private network) and wired networks. The note follows an international research that highlighted the vulnerability in WPA or WPA2 encryption that is most commonly used to connect to wireless networks. Researchers led by Mathy Vanhoef found that devices based on Android, iOS, Linux, macOS and Windows were among those vulnerable. They called this type of attack a key reinstallation attack, or KRACK.
