A global cybersecurity firm has urged Filipinos to take extra precautions when connecting to public Wi-Fi networks, warning that unsecured connections may expose users to data theft, credential harvesting, and malware attacks.
Choon Hong Chee, head of Consumer Channel for APAC at cybersecurity company Kaspersky, said free public Wi-Fi may offer convenience but can also carry serious cybersecurity risks.
He said many public networks require little or no authentication, allowing cybercriminals to monitor online activity, intercept personal information, and access sensitive data without the user’s knowledge.
The warning comes after the Department of Information and Communications Technology (DICT) issued an advisory reminding the public to practice safe browsing habits when using public Wi-Fi.
The DICT warned that unsecured networks may leave users vulnerable to cyberattacks. It advised the public to avoid using banking apps while connected to public Wi-Fi, verify the legitimacy of the network, disable auto-connect settings, and log out of accounts after use.
Chee said the government’s advisory is aligned with Kaspersky’s threat research, which shows that unsecured public networks can expose passwords, banking details, and private messages to anyone monitoring the connection.
To reduce the risk, Kaspersky advised users to avoid conducting sensitive transactions such as online banking when using public Wi-Fi. Users should also confirm the network name and details with the establishment providing the connection.
The cybersecurity firm also encouraged users to protect their data by using a reliable virtual private network and keeping their device firewall active to help block unauthorized access.
The company further recommended using strong and unique passwords, enabling two-factor authentication, and managing sensitive information through a trusted password manager instead of saving passwords or recovery phrases in a phone gallery or notes app.
Cybersecurity experts also advised users to install reliable security software, scan devices regularly, and keep operating systems, apps, and antivirus programs updated against emerging threats.
To prevent unauthorized access to files, users were reminded to disable file sharing and AirDrop when not in use.
Kaspersky added that travelers may also consider using an eSIM before going abroad to avoid relying heavily on public Wi-Fi networks for internet access.
