🧠 Tabnabbing Attack: When a Fake Tab Tricks You
Ever switch tabs in your browser and come back to a site that looks just like your email login? Be careful — you might be the victim of a Tabnabbing Attack, a clever trick used by cybercriminals to steal your credentials.
🕵️ What Is Tabnabbing?
Tabnabbing is a type of phishing attack where an inactive browser tab silently changes its content to mimic a login page (like Gmail, Facebook, or a bank).
When you return to that tab, you think your session expired — so you re-enter your username and password… right into the attacker’s hands.
⚙️ How It Works
- You open a legitimate-looking site in a new tab
- You switch to another tab and stay away for a while
- The inactive tab automatically reloads to show a fake login page
- You come back, see the login form, and enter your credentials
- The data is sent to the attacker
🧪 Why It’s Dangerous
- Looks completely normal to the average user
- Doesn’t require malware — just JavaScript and patience
- Can target any popular service (Google, Facebook, banks)
- Works on most modern browsers
🛡️ How to Protect Yourself
- 🔐 Use a password manager — it won’t fill forms on fake pages
- 🔎 Double-check the URL before logging in
- ⚠️ Be suspicious of login forms in tabs you didn’t open
- 🚫 Don’t stay logged in on sensitive sites for long periods
- 🔄 Close unused tabs, especially after logging into secure accounts
🧠 Final Thoughts
Tabnabbing is simple, silent, and easy to fall for — especially when you're multitasking.
In the world of cybersecurity, awareness is your first defense.
Think before you type. Not every login screen is what it seems.
