Beware of ’Evil Twin’ attacks when using public Wi-Fi networks

Colombo, October 29 (Daily Mirror) - The Sri Lanka Computer Emergency Readiness Team (SLCERT) is urging the public to exercise caution when using public Wi-Fi networks due to the risk of 'Evil Twin' attacks.

These attacks involve hackers setting up fake networks that mimic legitimate ones, potentially compromising users' sensitive information.

Cybersecurity experts are warning about these "evil twin" attacks, a type of Man-in-the-Middle (MitM) threat in which hackers create fake Wi-Fi networks to steal data or gain access to devices. These rogue networks, designed to resemble legitimate free Wi-Fi, often lure unsuspecting users in popular public locations such as airports, cafes and parks.

Hackers can deploy these networks almost anywhere, making it easier to intercept private information from connected devices. Security professionals advise users to be cautious when connecting to unfamiliar Wi-Fi networks, especially in public spaces, to avoid falling victim to these deceptive tactics.

These fake networks, often set up alongside legitimate Wi-Fi services, enable cybercriminals to intercept sensitive data, such as passwords and personal account information.

SLCERT advises the public to avoid accessing personal accounts, emails, or performing any financial transactions when connected to public Wi-Fi networks to minimise security risks.
