A malicious Chrome extension named "Safery: Ethereum Wallet" reached fourth place in Chrome Web Store search results for "Ethereum wallet" in November, according to Socket, a security firm specializing in open-source software supply chain analysis.

Market participants view the development as a potential signal for institutional access, though regulatory clearance remains pending.
