A Study on Malicious Browser Extensions in 2025

Browser extensions are additional tools developed by third parties that integrate with web browsers to extend their functionality beyond standard capabilities. However, the browser extension platform is increasingly being ex-ploited by hackers to launch sophisticated cyber threats.

These threats encompass a wide range of malicious activities, including but not limited to phishing, spying,Distributed Denial of Service (DDoS) attacks, email spamming, affil-iate fraud, malvertising, and payment fraud. This paper examines the evolving threat landscape of malicious browser extensions in 2025, focusing on Mozilla Firefox and Chrome.

Our research successfully bypassed security mechanisms of Firefox and Chrome, demonstrating that malicious exten-sions can still be developed, published, and executed within the Mozilla Add-ons Store and Chrome Web Store. These findings highlight the persisting weaknesses in browser’s vet-ting process and security framework.

"Browser Fingerprinting Using WebAssembly", 2025.

Abstract—Web client fingerprinting has become a widely used technique for uniquely identifying users, browsers, operating systems, and devices with high accuracy. While it is beneficial for applications such as fraud detection and personalized expe- riences, it also raises privacy concerns by enabling persistent
tracking and detailed user profiling. This paper introduces an advanced fingerprinting method using WebAssembly (Wasm)—a low-level programming language that offers near-native execution speed in modern web browsers. With broad support across major browsers and growing adoption, WebAssembly provides a strong foundation for developing more effective fingerprinting methods. In this work, we present a new approach that leverages WebAssembly’s computational capabilities to identify return- ing devices—such as smartphones, tablets, laptops, and desk- tops—across different browsing sessions.

Our method uses subtle differences in the WebAssembly JavaScript API implementation to distinguish between Chromium-based browsers like Google Chrome and Microsoft Edge, even when identifiers such as the User-Agent are completely spoofed, achieving a false-positive rate of less than 1%. The fingerprint is generated using a combination of CPU-bound operations, memory tasks, and I/O activities to capture unique browser behaviors. We validate
this approach on a variety of platforms, including Intel, AMD,
and ARM CPUs, operating systems such as Windows, macOS,
Android, and iOS, and in environments like VMWare, KVM, and VirtualBox.

Extensive evaluation shows that WebAssembly-based fingerprinting significantly improves identification accuracy. We also propose mitigation strategies to reduce the privacy risks
associated with this method, which could be integrated into future browser designs to better protect user privacy.
