⚠️ The Hidden Dangers of Using Public Wi-Fi: What You Need to Know

Public Wi-Fi is everywhere — in cafes, airports, malls, and hotels. It’s convenient, fast, and free. But behind the ease lies a serious cybersecurity risk that most people don’t even think about.

🔐 What’s the Real Risk?

When you connect to a public Wi-Fi network, your data is exposed. Hackers often set up fake networks (called “Evil Twins”) that look legitimate. Once you're connected, they can:

Intercept your traffic (Man-in-the-Middle attacks)

Steal your login credentials

Inject malware into your device

Spy on your browsing habits

Hijack your online sessions (session hijacking)

🧠 Real-World Scenarios

You log into your bank while sipping coffee. A hacker nearby captures your credentials.

You use public Wi-Fi at an airport. Malware silently installs on your phone.

You connect to "Free_WiFi" in a mall — but it’s not real. It’s controlled by an attacker who sees everything you do.

🛡️ How to Protect Yourself

  1. Never log in to sensitive accounts (banking, email, work) on public Wi-Fi.

  2. Use a VPN – It encrypts your data, making it unreadable to attackers.

  3. Disable auto-connect to Wi-Fi networks.

  4. Use HTTPS websites only.

  5. Turn off sharing options on your device.

  6. Keep your OS and antivirus updated

💡 Final Thoughts

Public Wi-Fi is a trap for the unaware. A few seconds of careless browsing can cost you your identity, your data, or even your bank account. Always assume that everything on public Wi-Fi is being watched — and act accordingly.

Stay smart. Stay encrypted.
