Uncover the ShadyPanda Scheme: How Millions of Users Were Tracked via Chrome and Edge Extensions (2026)

A shocking revelation has come to light, exposing a massive malware scheme that affected millions of unsuspecting users. The story of ShadyPanda and their malicious extensions is a cautionary tale of online privacy and security.

It all began in 2018 when a user, ShadyPanda, started uploading seemingly harmless browser extensions to the Chrome and Edge stores. These extensions appeared to be standard tools, and over seven years, they gained the trust of millions of users. But here's where it gets controversial: once the install base reached a critical mass, ShadyPanda unleashed a malicious update, transforming these extensions into powerful spyware.

Koi Security, while analyzing extension behavior, uncovered this sinister activity. Their report revealed the true scale of the incident, with one extension, WeTab, and several others from the same publisher, reaching over 3 million installs across Edge and Chrome. This is a stark reminder of the potential dangers lurking in our browsers.

While the threat has been removed from the stores, users must still take action. The malicious update allowed the extensions to capture a vast amount of browsing data, including every URL visited, the full browsing history, and even search queries. It logged mouse clicks, collected detailed browser fingerprints, and tracked user movements between sites. This level of surveillance is a serious invasion of privacy.

Google and Microsoft have confirmed the removal of these malicious extensions from their respective stores, but that's not enough. Users should review their browsers and remove any extensions published by Starlab Technology or linked to WeTab. It's also wise to uninstall any unrecognized or unused extensions.

Updating Chrome or Edge is another crucial step. The latest versions of these browsers implement enhanced security checks and built-in blocklists, which can disable any malicious extensions. A fresh update ensures that no old, cached extensions remain active.

But the story doesn't end there. The malware also stored persistent identifiers in chrome.storage.sync, which can follow users across devices. Even after reinstalling the browser, your profile might still be trackable. To fully remove these identifiers, users must clear their sync data after uninstalling the affected extensions.

This incident serves as a stark reminder of the importance of online security and privacy. It's a call to action for all users to be vigilant and take control of their digital footprint. And this is the part most people miss: online security is an ongoing process, and staying informed is key.
