Chrome Store Hosts 'Poper Blocker' Spyware Downloaded by Millions

A browser extension called 'Poper Blocker' available on the Chrome Web Store operates as spyware, exfiltrating sensitive user data while posing as an ad-blocker. The extension remained available despite researcher notifications to Google about its malicious behavior.

Why it matters: Users who installed this extension face data theft and privacy compromise; security teams should audit deployed extensions and consider restricting unapproved Chrome Web Store installs.
