You Can Now Block Phishing Wi-Fi Networks with a Click of a Button


Free Wi-Fi application Freefi (CEO: Jae-Hong Yoo) announced the debut of phishing-free feature, which detects and blocks access to phishing Wi-Fi networks.

Currently, there are more than 3,000 public and private Wi-Fi networks installed in Seoul. Especially in downtown areas with heavy foot traffic, multiple accessible public Wi-Fi around the area facilitates wireless network connection.

With the increase of public Wi-Fi, there has been a growing number of cybercrime cases abusing the use of such wireless networks. According to the National Police Agency, 907 damage incidents caused by the exploitation of wireless routers usage were reported from last May to October, with the damages amounting to 5.97 billion KRW (5 million USD).

One of the widely used phishing methods is through tweaking a wireless router’s Service Set Identifier (SSID) from an existing SSID. For instance, the Ministry of Science, ICT, and Future Planning’s public Wi-Fi SSID ‘public wifi @free’ is modified into ‘public wifi free’. Similarly, by capitalizing a letter such as ‘Olleh’ or by adding one number such as “T-Wifi Zone-1”, cybercriminals can easily induce users for micropayment transactions, Domain Name Server (DNS) falsification, and malware dissemination – among other cybercrimes.

To that end, Freefi developed the abovementioned phishing-free feature in an effort to prevent further phishing Wi-Fi cybercrime incidents. Through its self-developed algorithms, Freefi will protect users’ mobile phones by only connecting their devices to pre-verified Wi-Fi networks. Users can simply block access to phishing Wi-Fi by running the application.

“Witnessing numerous phishing-induced damage incidents has led us to create this phishing-free function, which effortlessly blocks malicious Wi-Fi networks,” said Jae-Hong Yoo, Pience CEO. “Through FreeFi, we strive to reduce data usage as well as to provide safer Wi-Fi network environment for our users.”

Freefi is an application that facilitates automatic Wi-Fi connections in more than 40,000 Freefi zones located in Seoul and Gyeonggi. By detecting signal intensity, Internet quality, security and safety through its self-developed algorithms, the app connects Wi-Fi networks available for users. In cases where no available Wi-Fi is identified, Freefi automatically converts Internet service to LTE or to 3G.

The company aims to further expand Freefi zones throughout the country based on the existing Freefi zones in Seoul and Gyeonggi, in addition to reducing household communication expenses and attracting diverse contents consumption.
