GoKawiilChrome Web Store's 'Featured' Poper Blocker Extension Found Stealing User Data
Researchers at Bay Area Labs say the Chrome extension Poper Blocker, which has over 2 million users and Google's 'Featured' and 'Established Publisher' badges, secretly collects browsing histories, screenshots and AI chatbot interactions. The extension uses code obfuscation and sandbox detection to avoid discovery, and the researchers say two other apps from the same developer, flagged as spyware nearly a decade ago, remain featured on the store. Bay Area Labs reported Poper Blocker to Google in May 2026 but says no action has been taken.
