260K+ CHROME USERS DUPED BY FAKE AI BROWSER EXTENSIONS

Summary from the TLDR InfoSec newsletter

More than 30 lookalike Chrome extensions posing as AI assistants have siphoned email, browser data, and sensitive inputs from over 260,000 users, including corporate environments. Attackers embed a full-screen iframe that proxies real LLM APIs while exfiltrating content and API keys, evading Chrome Web Store review due to minimal local permissions and off-platform malicious logic.
