Indian government agency Computer Emergency Response Team (CERT-in) has warned that the Public Wi-Fi hotspot or wireless internet networks installed at airports and railway stations are at risk of cyber attack. The researchers found Users of Android, iOS, Linux, macOS and Windows devices were most vulnerable to cyber attacks.
CERT-in said “Successful exploitation of these vulnerabilities allows an attacker to obtain sensitive information such as credit card numbers, passwords, messages, emails etc.”
CERT-in said that the vulnerability quotient of public Wi-Fi in India is at ‘high’ and advised people to avoid public Wi-Fi at all costs and to use virtual private networks and wired networks.
The warning has been issued after an international research that highlighted the vulnerability in WPA or WPA2 encryption that is most commonly used to connect to wireless networks. The researchers suggested using LAN till the vulnerability is addressed.
Here are few steps to secure your data:
- Always check to make sure there’s a green lock icon in the address bar of your browser.
- Use a virtual private network, which adds another layer of encryption to the data transferred from your device.
- Check firmware updates for your devices and install them
On Wednesday Microsoft has issued an update to address the vulnerabilities in Wi-Fi.
