DNS Hijacking Explained: How Hackers Redirect You to Fake Sites

Описание: You type your bank's URL. You see your bank's login page. But you're not on your bank's website.

That's DNS hijacking — and it's been working for over 40 years because the internet's "phonebook" was never designed to check who it was talking to.

In this breakdown we cover how DNS actually works, why it was built to trust strangers, the four main ways attackers hijack it (rogue routers, malware, cache poisoning, and registrar breaches), the real 2019 Sea Turtle campaign that rerouted 40+ organizations without breaking encryption, the red flags to watch for, and the four habits that actually protect you.

🛡️ QUICK PROTECTION CHECKLIST
• Turn on DNS-over-HTTPS in your browser (Chrome, Edge, Firefox, Safari)
• Enable registrar lock AND multi-factor authentication on every domain
• Always verify HTTPS and a valid certificate before logging in
• Update your router's firmware at least twice a year
• Don't trust public Wi-Fi DNS — use a trusted resolver or a VPN

Have you ever seen a "your connection is not private" warning — and clicked through anyway? Tell us about it below. That warning is often the only thing standing between you and a hijacked DNS response.
