Chrome Automatically Downloads Multi-Gigabyte Gemini Nano AI Model on May 9, Sparks Crypto Community Security Concerns

According to BlockBeats, on May 9, Chrome automatically downloaded a multi-gigabyte AI model file (Gemini Nano) to users' devices without explicit consent for local fraud detection, webpage summarization, and AI features.

While Google stated that local AI execution enhances privacy and security, crypto users raised concerns about the lack of transparency and explicit authorization. As browsers increasingly serve as core entry points for crypto wallets, on-chain transactions, and DApps, the move has heightened industry concerns about expanded attack surfaces, including malicious extensions, forged transaction pages, and wallet hijacking risks.
