Using public Wi-Fi can be risky because it often lacks proper security measures, making it easier for cybercriminals to intercept your data. Here are some common risks:

1. Man-in-the-Middle Attacks: Hackers can intercept data transmitted between your device and the Wi-Fi network, potentially stealing sensitive information like login credentials or credit card numbers.
2. Unencrypted Connections: Many public Wi-Fi networks don’t use encryption, meaning data sent over the network can be easily read by anyone with the right tools.
3. Malware Distribution: Cybercriminals can use public Wi-Fi to distribute malware, which can infect your device and compromise your data.
4. Rogue Hotspots: Fake Wi-Fi networks set up by hackers can trick users into connecting, allowing them to steal information or launch attacks.

To stay safe when using public Wi-Fi, consider these tips:

1. Use a VPN: A Virtual Private Network encrypts your internet traffic, making it much harder for anyone to intercept your data.
2. Enable HTTPS: Ensure websites you visit use HTTPS, which encrypts data between your browser and the website.
3. Avoid Sensitive Transactions: Refrain from accessing sensitive accounts or conducting financial transactions over public Wi-Fi.
4. Turn Off Sharing: Disable file and printer sharing on your device to prevent unauthorized access.
5. Keep Software Updated: Ensure your operating system and applications are up to date with the latest security patches.

By taking these precautions, you can reduce the risks associated with using public Wi-Fi.
