DNS hijacking is a serious cybersecurity threat that targets your internet activity by manipulating how your device connects to websites.
In Kenya, more people are experiencing strange redirects and slow connections—often without realizing they’ve fallen victim to this silent attacker.
In this guide, we’ll break down how DNS hijacking works, what signs to look out for, and most importantly, how you can stay safe online.
What is DNS Hijacking?
To understand DNS hijacking, you first need to know what DNS (Domain Name System) does. DNS works like a digital phonebook—it translates website names like google.com into IP addresses your computer can understand.
When DNS is hijacked, hackers intercept or alter this translation process.
As a result, users may be redirected to fake websites, experience unusual pop-ups, or unknowingly give away sensitive information.
This cyberattack is especially dangerous because it operates in the background, without any obvious signs.

Types of DNS Hijacking
There are several methods attackers use to hijack DNS. Understanding these types will help you recognize suspicious activity faster.
| Type of DNS Hijacking | Description |
|---|---|
| Router Hijacking | Hackers compromise your router and change its DNS settings. |
| Man-in-the-Middle Attack | An attacker intercepts your DNS request before it reaches a legitimate server. |
| Rogue DNS Server | Your system is redirected to a malicious DNS server controlled by hackers. |
| ISP-Level Hijacking | Internet Service Providers reroute your requests for data collection or ads. |
Each method poses a unique risk, but they all have one thing in common—they tamper with your internet experience in ways that expose you to fraud or surveillance.
How to Know If You’re a Victim
Staying alert is your first line of defense. Below are some common signs that could indicate DNS hijacking:
- You’re being redirected to suspicious websites
- Your browser displays unusual pop-ups
- Websites take unusually long to load or fail to open
- Security warnings appear frequently on trusted sites
These issues are subtle at first but can escalate quickly. Therefore, checking your router settings and running regular security scans is essential.
How to Stay Safe Online
Now that you understand how DNS hijacking works, here are effective ways to protect yourself:
1. Use a Trusted DNS Service
Instead of relying on default DNS settings, switch to secure options like:
| DNS Provider | Primary DNS | Secondary DNS |
|---|---|---|
| Google Public DNS | 8.8.8.8 | 8.8.4.4 |
| Cloudflare | 1.1.1.1 | 1.0.0.1 |
| OpenDNS | 208.67.222.222 | 208.67.220.220 |
These services offer better security and are less likely to be compromised.
2. Secure Your Router
- Always change the default admin credentials.
- Keep your router’s firmware up to date.
- Disable remote management features unless necessary.
Many Kenyan households use outdated routers that make them easy targets. Taking time to secure your home network is a powerful step toward online safety.
3. Use Antivirus and Anti-Malware Tools
These tools help detect and block suspicious activities. Choose a solution that offers DNS protection features to actively monitor potential threats.
4. Monitor DNS Settings Regularly
You should frequently check if your DNS settings have been changed without your knowledge. If you notice unknown IPs or servers, it’s time to act.
5. Use VPN Services
A reliable VPN encrypts your connection and reduces the risk of man-in-the-middle attacks. It also helps you avoid local ISP interference, which is a concern in some parts of Kenya.
Final Thoughts
DNS hijacking is a silent but dangerous threat facing internet users in Kenya. While it often goes unnoticed, its effects can be devastating—from data theft to privacy breaches. However, by staying informed and implementing smart protective measures, you can drastically reduce your risk.
