Why Public Wi-Fi Is Dangerous: Real Attack Scenarios and 5-Minute Protection<\/h1>\n

Airport, three hours before your flight. Your phone picks up a network called Free_Airport_WiFi<\/code>, even though you did not choose it \u2014 it connects automatically because you joined something similar once and your phone remembered it. You open your email, then your bank, then a work chat.<\/p>\n

At this point, by the rules of the genre, I should tell you how all your money was stolen. I won’t. Usually nothing happens: you fly home, nobody hacks you, and articles that claim otherwise often just want to sell something. But \u201cusually nothing happens\u201d is a poor basis for security decisions, especially when the risks are cheap to eliminate. I spent those five minutes once, and since then I only think about open networks when I write articles like this.<\/p>\n

Open network and unsafe network are not the same thing<\/h2>\n

Let’s start with what has changed: half the scary stories about public Wi-Fi are outdated, and, as far as I can tell, they are repeated by people who last checked the fundamentals ten years ago.<\/p>\n

Things really were bad before. Traffic used to travel over HTTP in plain text, and anyone on the same network could read it like a newspaper over a neighbor’s shoulder. There were browser extensions that exposed other people’s social-media sessions with one click \u2014 entertainment for a bored student, and I remember when it actually worked. Then HTTPS became standard, and that era ended. Today almost the entire web is encrypted. An email password cannot simply be intercepted: it is encrypted from your device to the server, and the hotspot owner sees meaningless bytes. So is public Wi-Fi safe? Let’s put it this way: the fact that the network is open is no longer the main problem. The problem is that you do not know who operates it, and HTTPS cannot solve that.<\/p>\n

Now, four scenarios that still work.<\/p>\n

Scenario one: a fake access point<\/h2>\n

Evil Twin, the malicious twin. The prettiest attack in the list and, in my opinion, one of the most underestimated.<\/p>\n

An attacker sets up their own hotspot with the same name as the real one: Coffee_Guest<\/code> next to Coffee_Guest<\/code>. Your phone sees two identical SSIDs and may choose the one with the stronger signal \u2014 and that signal is stronger because the attacker is sitting at the next table with a small device in a backpack. Your traffic now passes through their equipment. The annoying part is the price: an Evil Twin hotspot can be built with hardware about the size of a pack of cigarettes for a few thousand rubles, legally sold with ready-made firmware and tutorials online. No advanced hacking skills are required, and honestly, that bothers me more than anything else on this list.<\/p>\n

The owner of such a hotspot cannot read your HTTPS traffic; encryption still protects it. But they can redirect you to their own page, show a fake login form, or return a forged DNS response. How do you spot it? Honestly, reliably \u2014 almost impossible, and that is the unpleasant part. There are only indirect signs: a network that required a password yesterday but is open today; two identical names in the list; a signal that is unusually strong. If you see any of these, do not connect. Switch to mobile data \u2014 that is what I do.<\/p>\n

Scenario two: DNS spoofing<\/h2>\n

Less dramatic, but more common. And quite often there is no malicious intent: the network owner simply decided to filter something.<\/p>\n

DNS is the internet’s directory service: you name a site and it returns an address. Traditionally, DNS queries travel without encryption and without authentication, so whoever controls the network can answer them. Want the correct answer? Give it. Want to send the user somewhere else? Do that instead. HTTPS helps a lot: if you are redirected to an impostor server, the browser will not receive a valid certificate and will warn you about an unsafe connection. Never ignore that warning. I have never seen \u201ccontinue anyway\u201d on an unfamiliar network turn out to be a good idea. Encrypted DNS (DoH or DoT) partly helps in a browser. A tunnel protects it more completely by carrying DNS requests inside the encrypted connection.<\/p>\n

Scenario three: the login page<\/h2>\n

A captive portal is the page that opens automatically and asks you to accept terms, enter a phone number, or sign in through a social account. It has to intercept traffic to appear in the first place. Users are used to it: a form pops up, so it must be legitimate. That makes it excellent phishing territory.<\/p>\n

The rules are simple. Do not enter anything except a phone number if it is genuinely required. Do not sign in with a social account \u2014 the portal has no reason to need it. Do not install a \u201ccertificate for network access\u201d or configuration profiles. A foreign certificate can undermine HTTPS protection, turning the security described above into something you disabled yourself. I hate this part: the user can damage their own security voluntarily.<\/p>\n

And do not download applications from the portal. Any applications.<\/p>\n

Scenario four: metadata<\/h2>\n

This is underestimated because it is not about hacking. It is about what happens all the time \u2014 on a legitimate network, with HTTPS, even when you did everything correctly. It matters to me more than the other three.<\/p>\n

The content is encrypted. But the Wi-Fi owner can still see:<\/p>\n
