As technology has grown, the need for digital connectivity has increased. This has led to the rise of public Wi-Fi, which can be accessed in cafes, airports, hotels, and other public places. However, using public Wi-Fi while traveling can be risky. Below are some of the risks associated with using public Wi-Fi while roaming.
1. Security Concerns
Public Wi-Fi is more vulnerable to attacks, and hackers can easily intercept the data transmitted through these networks. For this reason, a user’s login credentials, bank account information, and private messages are vulnerable to theft. Hence, it is advisable to avoid using public Wi-Fi for browsing sensitive information like banking and personal data. Instead, use a virtual private network (VPN) to encrypt your online traffic.
2. Identity Theft
When using public Wi-Fi, hackers can impersonate the user’s device and gain access to their smart devices or laptops. They can then use the user’s private information for identity theft purposes. Once they gain access, they can install malware that steals the user’s details, including bank account information, social security number, and login passwords. Always be cautious and do not engage in activities that could compromise your identity.
3. Wi-Fi Sniffing
This refers to a technique used by hackers to intercept Wi-Fi traffic and collect data. The attacker sets up fake Wi-Fi networks with convincing names to lure unsuspecting users into connecting to it. The user’s device connects to the rogue Wi-Fi network, and the attacker can intercept personal data. Avoid using public Wi-Fi with unique names.
4. Malware Attacks
Hackers can place malicious software on a public Wi-Fi network, frequently distributed through downloads, on users’ devices. Attackers can infect unsuspecting users’ devices with viruses, spyware, and ransomware. They can then use the malware to steal personal data, damage devices, and lock users out of their devices.
Conclusion
While using public Wi-Fi, users need to be cautious and ensure that they protect their data. They can do this by avoiding public Wi-Fi for sensitive tasks, using VPNs, avoiding rogue Wi-Fi networks, and regularly updating their devices with the latest anti-virus. Protecting personal data is a shared responsibility, so always be vigilant and stay safe when using public Wi-Fi while roaming.
