Fake AdBlock Plus Extensions: Chrome Risks

Yes, Chrome users have been targeted by fake AdBlock Plus extensions. These malicious add-ons impersonate the legitimate AdBlock Plus to steal data, inject ads, or hijack browser settings. This article explains how these fakes operate, how to spot them, and how to stay safe.

Background: The Real AdBlock Plus vs. Fakes

AdBlock Plus (ABP) is one of the most popular browser extensions, with millions of users worldwide. Its success makes it a prime target for scammers. Fake versions appear in third-party download sites, phishing emails, or even as “cracked” or “premium” versions. Unlike the genuine extension, which is free and open-source, fakes often ask for excessive permissions or bundle malware.

How Fake AdBlock Plus Extensions Work

Fake extensions typically use one of several tactics:

Permission abuse: They request access to “read and change all data on all websites,” which allows them to see everything you type, including passwords and credit card numbers.
Ad injection: Instead of blocking ads, they inject their own ads into pages, generating revenue for the attacker.
Data theft: They collect browsing history, search queries, and form data, sending it to a remote server.
Browser hijacking: They change your homepage, default search engine, or redirect you to malicious sites.

How to Choose a Safe Ad Blocker

To avoid fakes, follow these guidelines:

Only use the official Chrome Web Store. Google reviews extensions, though not perfectly, so it’s the safest source.
Check the developer name. The genuine AdBlock Plus is published by “eyeo GmbH.” Look for that exact name.
Read reviews and ratings. Fakes often have few reviews or a sudden spike of positive reviews.
Check the install date. A legitimate extension that’s been around for years will show an older “Updated” date.
Look for the “Verified” badge. Google now verifies some publishers, though not all legitimate ones have it.

Common Problems with Fake Extensions

Users who install a fake AdBlock Plus often report:

Ads still appear, or new pop-ups appear.
Browser becomes slow or crashes.
Homepage or search engine changes without permission.
Unwanted toolbars or other extensions appear.
Bank or email accounts show suspicious activity.

How to Remove a Fake Extension

If you suspect you have a fake extension, remove it immediately:

Open Chrome and click the three-dot menu (⋮) in the top right.
Go to Extensions → Manage Extensions.
Find the suspicious extension and click Remove.
If you can’t remove it, reset Chrome settings: In Settings, search for “Reset” and choose “Restore settings to their original defaults.” This disables all extensions.
Run a full antivirus scan on your computer.
Change your passwords, especially for email and banking, from a clean device.

Comparison: Fake vs. Real AdBlock Plus

Here’s a quick comparison:

Feature	Real AdBlock Plus	Fake Extension
Source	Chrome Web Store	Third-party sites, phishing links
Developer	eyeo GmbH	Unknown or impersonated
Permissions	Minimal, necessary for ad blocking	Excessive, “all data on all websites”
Behavior	Blocks ads, no pop-ups	Injects ads, pop-ups, redirects
Cost	Free	May ask for payment or “donation”

Safety and Prevention Tips

Beyond choosing carefully, practice good security hygiene:

Keep Chrome and your operating system updated.
Use a reputable antivirus and enable real-time protection.
Be wary of any extension that asks for payment or personal information.
Regularly review your installed extensions and remove any you don’t use.
Use Chrome’s built-in Safe Browsing (it’s on by default) and avoid downloading from pop-ups.

Frequently Asked Questions

How can I tell if my AdBlock Plus is fake?

Check the extension’s details in Chrome: the developer should be “eyeo GmbH.” If it’s anything else, or if you see ads appearing, it’s likely fake. Also, the real ABP never asks for payment or personal data.

Can a fake extension steal my passwords?

Yes. If the extension has permission to read all data on all websites, it can capture keystrokes and form submissions, including passwords and credit card numbers. Change your passwords immediately if you suspect a fake.

What should I do if I already installed a fake?

Remove it immediately, reset Chrome settings, run an antivirus scan, and change your passwords from a secure device. Monitor your accounts for any unauthorized activity.

Are all ad blockers risky?

No. The most popular ones (AdBlock Plus, uBlock Origin, etc.) are safe when downloaded from official sources. The risk comes from unofficial sources or look-alike extensions.

Does AdBlock Plus cost money?

No, the genuine AdBlock Plus is free. If you see a version asking for payment, it’s a scam. Some legitimate ad blockers offer premium features, but ABP itself is free.
