Browser extensions have become as common as mobile apps. People tend to download many and use few. There are over 176,000 browser extensions available on Google Chrome alone. These extensions offer users extra functionalities and customisation options.
While browser extensions enhance the browsing experience, they also pose a danger which can mean significant risks to online security and privacy.
In this article, we unravel the dangers associated with browser extensions. We’ll shed light on the potential threats they pose as well as provide insights into safeguarding your online presence.
The Allure and Perils of Browser Extensions
Browser extensions are often hailed for their convenience and versatility. They are modules that users can add to their web browsers. They extend functionality and add customisable elements.
From ad blockers and password managers to productivity tools, the variety is vast. But the ease with which users can install these extensions is a weakness because it also introduces inherent security risks.
Next, we’ll delve into the hazards associated with browser extensions. It is imperative to strike a balance between the benefits and dangers.
Key Risks Posed by Browser Extensions
Privacy Intrusions
Many browser extensions request broad permissions. If abused, they can compromise user privacy. Some of these include accessing browsing history and monitoring keystrokes. Certain extensions may overstep their intended functionality. This can lead to the unauthorised collection of sensitive information.
Users often grant permissions without thoroughly reviewing them. This causes them to unintentionally expose personal data to potential misuse.
Malicious Intent
There are many extensions developed with genuine intentions. But some extensions harbour malicious code. This code can exploit users for financial gain or other malicious purposes. These rogue extensions may inject unwanted ads. As well as track user activities or even deliver malware.
These extensions often use deceptive practices. They make it challenging for users to distinguish between legitimate and malicious software.
Outdated or Abandoned Extensions
Phishing and Social Engineering
Some malicious extensions engage in phishing attacks as well as social engineering tactics. These attacks can trick users into divulging sensitive information.
This can include creating fake login pages or mimicking popular websites. These tactics lead unsuspecting users to unknowingly provide data. Sensitive data, like usernames, passwords, or other confidential details.
