🚨 Over 6 million Chrome users may have unknowingly installed extensions with hidden tracking code — some with spyware-like behavior.

Researcher John Tuckner from Secure Annex discovered 57 extensions, some of them public, others hidden and only accessible via direct URL. These extensions pose serious security and privacy risks.

Here’s what these extensions can do:
- Access cookies, including sensitive headers like 'Authorization'
- Monitor browsing behavior and collect top-visited sites
- Modify search engines and results
- Inject remote scripts into webpages via iframes
- Execute commands remotely, including opening/closing tabs
- Activate tracking features on demand

Some extensions claim to be security or privacy tools — including names like “Fire Shield Extension Protection,” “Securify,” and “Browser Checkup” — but contain heavily obfuscated code and suspicious external callbacks to domains like "unknow (dot) com".

📛 These extensions are:
- Not searchable on the Chrome Web Store
- Actively pushed via ads and shady websites
- Operating under broad permissions without clear purpose
- Still live in some cases, despite partial takedowns

Here are some of the most-downloaded suspicious extensions:
- Cuponomia – Coupon and Cashback (700,000 users)
- Fire Shield Extension Protection (300,000 users)
- Browser WatchDog for Chrome (200,000 users)
- Securify for Chrome™ (200,000 users)
- Total Safety for Chrome™ (300,000 users)

If you use Chrome:
- Review your installed extensions
- Remove any of the above immediately
- Reset passwords for accounts you’ve accessed recently
- Avoid installing browser tools from unverified sources

🔐 At @Efani we believe privacy tools shouldn’t come with surveillance built in. Always check extension permissions — and if it asks for too much, it’s probably taking more than it gives.

I am going to keep @ChromeVoiceActions and my other extensions on MV2 and test them on older Chromebooks for as long as Google lets me, and when Chrome tries to disable them, you can go to chrome://extensions and manually re-enable them. I hope this explanation helps; thank you for understanding! (4/4)

A panel in Chrome extension settings says, These extensions were turned off because they're no longer supported.  Chrome recommends that you remove them.  Learn more about supported extensions.  The list includes Touch-Friendliness for Discord, Voice Actions for Chrome, and XKCD Hover Text.  Select More actions → Keep for now.A confirmation dialog says, Keep Voice Actions for Chrome?  This extension is no longer supported.  Chrome recommends that you remove it instead.  Select Keep.

🐱 Looks like Google's playing cat and mouse with extension developers! After 7 years of "improvements," devs are still chasing their tails with MV3 platform issues. Even Privacy Badger can't properly catch those sneaky tracking redirects anymore. Sometimes the mouse wins! 🐭 #ChromeExtensions #Privacy
