Dangers about Using Public Wi-FI | Generated by AI
Using public Wi-Fi or hotel Wi-Fi can be risky because these networks are often insecure or poorly configured, making them easy targets for attackers. Here are the main dangers:
🔓 1. No Encryption (or Weak Encryption)
- Many public networks use no encryption or WEP, which can be cracked easily.
- This means attackers can see your traffic in plaintext—like login credentials or emails.
🕵️♂️ 2. Man-in-the-Middle (MitM) Attacks
- An attacker on the same network can intercept your data or even alter it in transit.
- They can pose as the Wi-Fi access point (e.g., set up a fake “FreeHotelWiFi”).
📥 3. Malware Distribution
- Some compromised hotspots may inject malicious code into HTTP websites.
- Malware can be automatically downloaded to your device.
🧑💻 4. Session Hijacking
- Attackers can steal cookies from sites you visit, letting them impersonate you (e.g., Facebook, Gmail).
- This works especially on websites without full HTTPS protection.
🌐 5. Evil Twin Attacks
- A rogue hotspot with the same name as the legitimate network can trick you into connecting.
- Once connected, attackers can log or manipulate everything you send or receive.
🔐 6. Credential Theft
- Logging into apps or websites over public Wi-Fi can expose your usernames and passwords—especially if the site isn’t using HTTPS correctly.
⚠️ 7. Data Snooping by Network Providers
- Hotels or cafés may log your traffic for tracking, monetization, or surveillance.
🔒 How to Stay Safe on Public Wi-Fi
- ✅ Use a VPN – encrypts all your traffic.
- 🔐 Use HTTPS – look for the padlock in the browser.
- 📵 Avoid sensitive tasks – like online banking or private work.
- 🛑 Turn off sharing – file/printer sharing, AirDrop, etc.
- 🚫 Forget the network after use – to avoid auto-reconnect.
- 📲 Use mobile data/hotspot instead – more secure for sensitive stuff.
