Malicious Perplexity Chrome Extension Compromises User Data
In June 2026, Microsoft identified a malicious Chrome extension named "Search for perplexity ai" that impersonated the AI search engine Perplexity. This extension intercepted users' search queries and address bar inputs, routing them through an attacker-controlled server before redirecting to legitimate search results. The extension set itself as the default search engine upon installation, capturing every character typed into the address bar and transmitting this data, along with browser headers, IP addresses, and user agents, to the attacker's server. Microsoft reported the extension to Google, leading to its removal from the Chrome Web Store.

Similar campaigns have targeted users by masquerading as AI assistants, leading to significant data breaches. Organizations must remain vigilant, implementing strict policies on browser extensions and educating users about the risks associated with unverified add-ons.
