When using public Wi-Fi networks, it is important to be aware of potential cyber threats such as phishing scams and malware attacks. Phishing scams involve cybercriminals posing as legitimate entities to obtain personal information, while malware attacks involve cybercriminals planting malicious software on a device to gain access to sensitive information. These threats can be particularly prevalent on public Wi-Fi networks, as they are often unsecured and easily accessible to hackers. To protect against these threats, it is recommended to use a virtual private network (VPN) and avoid accessing sensitive information or making online purchases on public Wi-Fi networks. Additionally, investing in an encrypted flash drive can help protect personal data from potential cyber threats.
