- Browser extensions can pose significant security and privacy risks.
- The Mellowtel library allows developers to monetize their extensions by using users' bandwidth.
- Digital minimalism and regular auditing of extensions and apps are crucial for online safety.
Intro
The video introduces a concerning issue where browser extensions are turning nearly one million browsers into website scraping bots. The presenter aims to explain the problem, its implications, and what users can do to protect themselves, while also raising ethical questions about browser extension monetization.
Which extensions were impacted?
The presenter lists several extensions affected by this issue, ranging from seemingly harmless tools like Netflix 1080p to privacy-oriented extensions like User Agent Switcher. The variety of extensions on the list suggests that many users may be affected, even by extensions they installed years ago for simple functionalities like dark mode or feature enhancements.
Intro to Mellowtel library
The issue stems from the use of Mellowtel, an open-source library that allows developers to monetize their browser plugins. Mellowtel argues that it provides an alternative to advertising and surveillance industries, offering a way for developers to earn revenue.
How Mellowtel Works
Mellowtel functions by having developers implement it into their extensions, which then requests specific permissions to generate incognito windows in the background. Users contribute their unused bandwidth to the extension, which sends device information such as location, bandwidth availability, heartbeats, and status. This process involves loading an iframe, which can be manipulated to steal data or exploit security vulnerabilities, bypassing website security policies like content security policies and x-frame options.
The problems
The presenter expresses concerns about users being unaware that their bandwidth is being used and the implications for consent. There are potential performance impacts and privacy risks due to data transmission. The security risks are significant because the extensions bypass standard web browsing security measures, making users vulnerable to attacks like cross-site scripting. The presenter also notes the sketchiness of the extension owner having multiple extensions that don't appear to be connected.
Sponsor: redact.dev
The video includes a sponsorship message for redact.dev, a tool that helps users automatically find and delete old messages, attachments, and images from social media accounts and other platforms. Redact.dev is highlighted for its trustless nature, as it doesn't store user credentials and operates locally on the user's machine.
Digital Minimalism
The presenter advocates for digital minimalism, advising users to only install essential extensions. They mention using only Ublock Origin, a safe and trusted extension, and a password manager in their browsers.
Rationale behind keeping things minimal
Extensions often lack strong security and privacy measures and have extensive access to user systems, increasing the risk of misuse. Reducing the number of extensions minimizes the potential for data breaches and privacy violations.
Recommended Action Steps!
The presenter recommends several action steps:
- Check if your extensions are on the list of impacted extensions.
- Remove extensions you no longer use.
- Remove a few extra extensions to minimize risk.
- Prioritize extensions from companies with established business models independent of the extension itself (e.g., password managers like Proton Pass or Bitwarden).
- Avoid extensions that are the entire product.
- Seek dedicated solutions instead of relying on extensions (e.g., using browsers with built-in dark mode readers).
Broader Implications and why this matters.
The incident highlights the need for greater scrutiny of extension stores and their responsibility to ensure the safety and transparency of extensions. Browsers are moving towards systems that reduce the permissions extensions can have, which improves security. The presenter emphasizes that these issues extend beyond extensions to apps and programs, urging users to audit their devices and ensure trustworthy solutions are in place.
Important Ethical questions
The presenter raises ethical questions about how developers can sustain themselves without compromising user privacy. While Mellowtel aims to provide an alternative to traditional surveillance systems, it's important to consider whether it's the right approach. The presenter encourages viewers to reflect on the best long-term solutions for supporting developers while protecting users.
Final Words
The presenter urges viewers to share the video, check their extensions, and join the community for more security updates. They thank redact.dev for sponsoring the content and encourage viewers to leave their thoughts and perspectives in the comments.
