Real Incident: Business Email Compromised
A Perth business owner's email account was compromised while using hotel WiFi. Hackers gained access, impersonated him, and rerouted client payments.
That's not rare — it's routine.
Why Public WiFi Is Unsafe
Anyone can listen.
Most free WiFi networks are unencrypted, meaning your data travels in the open. Attackers nearby can capture passwords, emails, and banking details.
Fake hotspots fool you.
Hackers create "evil twin" networks like Free_Airport_WiFi or CoffeeShop_Guest to trick users into connecting.
Man-in-the-Middle attacks.
Once connected, attackers can intercept your web traffic and modify what you see — even inject malware.
Session hijacking.
Logging into email or business portals over open WiFi gives attackers a window into your accounts.
Device exposure.
Public networks can allow file-sharing or printer discovery by default — exposing your laptop to others on the same network.
How to Tell If It's Safe
| Red Flag | What It Means | What to Do |
|---|---|---|
| Network is "Open" (no password) | Unencrypted, anyone can snoop | Avoid for anything sensitive |
| Misspelled or duplicate name | "Evil twin" hotspot | Ask staff which SSID is real |
| Login page asks for personal data | Phishing risk | Close it immediately |
| HTTPS sites fail to load | Possible interception | Disconnect |
| Reconnects automatically | Old saved hotspot | Forget it after each use |
How to Protect Yourself
- Use a VPN. Encrypts your data end-to-end.
- Stick to HTTPS sites only. Look for the padlock icon.
- Turn off sharing. Disable file and printer sharing in Windows/macOS settings.
- Use mobile data when possible. Hotspot your phone for secure access.
- Enable Multi-Factor Authentication (MFA). Prevents stolen credentials from being used.
- Never access banking, payroll, or business portals over free WiFi.
- Run managed security software. Keep your antivirus and firewall up-to-date — skip "free" virus apps that steal data.
Bottom Line
Public WiFi isn't "free" — you pay with your security.
If you must connect, treat every open network as hostile.
Use a VPN, verify the network name, and avoid logging into anything that matters.
If you're a business owner, make this part of your employee cybersecurity policy.
