Dear 404: Are free Wi-Fi networks dangerous?
A curious character in the shape of a brain

Dear 404,

Are free Wi-Fi networks actually dangerous, or is that just a myth?

— Myth-or-Maybe

Dear Myth-or-Maybe,

Ah yes — free Wi-Fi. The holy grail of airports, cafés, and “I refuse to use roaming data” moments.

So… is it dangerous?

Short answer: Not automatically — but it can be.

Let’s break it down.

What’s the actual risk?

Public Wi-Fi networks (coffee shops, airports, hotels) are shared spaces. That means:

  • Other people are on the same network as you.
  • The network may not be encrypted properly.
  • You don’t actually know who set it up.

That creates a few potential problems:

Snooping: On poorly secured networks, attackers can intercept unencrypted traffic. If a website doesn’t use HTTPS (most reputable ones do now), someone could potentially see what you’re sending.

Fake Wi-Fi Networks: Sometimes attackers set up networks with names like:

  • “Airport_Free_WiFi”
  • “Starbucks_Guest”
  • “Hotel Lobby WiFi”

You connect. They watch. Not ideal.

Man-in-the-Middle Attacks: This is when someone positions themselves between you and the website you’re visiting, quietly capturing or altering traffic.

Sounds dramatic. Sometimes it is.

So… should you panic?

No

How to use free Wi-Fi safely (without giving it up forever)

Dear 404 recommends:

  • University community (staff, faculty students): Before you connect to university systems or data, make sure you’re on UTORvpn. Always. (Yes, even if you’re “just checking one thing.”)
  • Stick to HTTPS websites when browsing (look for the lock icon in your browser).
  • Avoid sensitive transactions (banking, payroll systems, admin portals, or any system where your access the personal information of others) unless you’re on a trusted network.
  • Turn off automatic Wi-Fi connections so your device doesn’t join random networks.
  • Confirm the network name with staff before connecting.
  • Use MFA everywhere. If someone somehow grabs your password, they still can’t get in.

  • Keep your device updated. Patches matter.

If you’re especially cautious, using your phone’s hotspot for sensitive tasks is a safer move than public Wi-Fi.

The bottom line

Free Wi-Fi isn’t evil — but it is unpredictable.

Think of it like crossing a busy street. Most of the time, nothing happens. But you still look both ways.

Use it with awareness. Browse, check email, do light work if you need to. But when it comes to banking, payroll, university systems, or anything sensitive — wait until you’re on a network you trust.

You don’t have to fear it. Just don’t get too comfortable.

Be cautious. That’s the sweet spot.

Sincerely,
