ad blocking

Ad blocking extensions can pose serious security risks beyond blocking advertisements. A recent security report identified two browser ad-blocking extensions, Smart Adblocker and Adblock for Browser, that secretly intercepted AI conversations and account metadata from roughly 90,000 users across platforms like ChatGPT, Claude, Gemini, Copilot, Perplexity, DeepSeek, Grok, and Meta AI. This operation, dubbed PromptSnatcher, highlights how ad blocking tools can be weaponized to steal sensitive data, including AI prompts and metadata. For Windows users, this underscores the importance of vetting browser extensions carefully, as ad blocking software may compromise privacy and security, especially when accessing AI services through browsers.
