• Rogue access points: Unauthorized Wi-Fi access points can be set up to lure users into connecting, facilitating data theft and malware installation.
• Unencrypted networks: Many public Wi-Fi networks lack encryption, making data transmitted over them vulnerable to interception.
• Ad hoc networks: Devices may connect directly to each other without proper security measures, increasing the risk of data breaches.
• Shoulder surfing: In public spaces, attackers may physically observe users entering sensitive information, such as passwords or PINs.

Being aware of these threats is the first step towards enhancing public Wi-Fi safety. Implementing protective measures can significantly reduce the risk of falling victim to cyberattacks.

Evil twin hotspots are fraudulent Wi-Fi networks set up by cybercriminals to mimic legitimate public Wi-Fi connections. These malicious networks often use names similar to trusted establishments, such as "Free Café Wi-Fi" or "Airport_Public," to deceive users into connecting.

Once a user connects to an evil twin hotspot, the attacker can monitor and intercept all data transmitted over the network. This includes sensitive information like login credentials, personal messages, and financial details. In some cases, attackers may redirect users to phishing websites designed to capture additional personal information.

Setting up an evil twin hotspot is relatively simple and requires minimal technical expertise. Attackers use readily available hardware and software to create these rogue networks, making them a prevalent threat in public spaces.

In India, where public Wi-Fi usage is on the rise, the risk of encountering evil twin hotspots is significant. Users must exercise caution and verify the authenticity of Wi-Fi networks before connecting. Employing security measures such as Virtual Private Networks (VPNs) and avoiding the transmission of sensitive information over public networks can help mitigate these risks.

Ensuring public Wi-Fi safety requires proactive measures to safeguard personal information and devices. Here are some practical tips:

• Use a VPN: A Virtual Private Network encrypts your internet connection, protecting data from potential eavesdroppers.
• Verify network authenticity: Confirm the exact name of the Wi-Fi network with the establishment to avoid connecting to rogue hotspots.
• Avoid accessing sensitive information: Refrain from logging into banking or other sensitive accounts while on public Wi-Fi.
• Keep software updated: Regularly update your device's operating system and applications to patch security vulnerabilities.
• Disable file sharing: Turn off file sharing options to prevent unauthorized access to your device.
• Use HTTPS websites: Ensure websites use HTTPS, indicating a secure connection, especially when entering personal information.
• Turn off auto-connect: Disable automatic connection to Wi-Fi networks to prevent unintended connections to malicious networks.
• Enable firewall and antivirus protection: Use reputable security software to detect and block potential threats.
• Log out after use: Always log out of accounts after use to prevent unauthorized access.
• Monitor your accounts: Regularly check bank and credit card statements for unauthorized transactions.

By implementing these measures, users can significantly enhance their security when using public Wi-Fi networks.

In India, cybercrimes related to public Wi-Fi usage are addressed under various legal provisions. The Information Technology Act, 2000, and the Indian Penal Code (IPC) provide the legal framework to combat such offenses.

Section 66C of the IT Act deals with identity theft, where individuals fraudulently use others' personal information. Section 66D addresses cheating by personation using computer resources, applicable in cases like evil twin hotspot scams. Violations under these sections can lead to imprisonment of up to three years and fines.

Additionally, Sections 419 and 420 of the IPC pertain to cheating and dishonestly inducing delivery of property, which can be invoked in cases of financial fraud over public Wi-Fi networks. Convictions under these sections can result in imprisonment of up to seven years and fines.

Victims of public Wi-Fi-related cybercrimes can file complaints with the Cyber Crime Cell or report incidents through the National Cyber Crime Reporting Portal (https://cybercrime.gov.in/). Prompt reporting and cooperation with law enforcement agencies are crucial for effective legal recourse.

The proliferation of public Wi-Fi networks has transformed how individuals access financial services and conduct online banking. While offering convenience, these networks also introduce significant security risks.
