Overview

• Perplexity removed the waitlist and made its Chromium-based Comet browser free for global desktop users after months in a paid beta.
• LayerX detailed a 'CometJacking' attack that uses a malicious URL to hijack the assistant and exfiltrate emails, calendar entries and other data from connected services.
• Brave’s security team reported similar risks where page-embedded prompts could trick Comet into accessing data from other tabs.
• Perplexity told LayerX in August it could not identify any security impact and marked the disclosure as not applicable under its reporting system.
• CEO Aravind Srinivas promoted Comet as a personal assistant that could reduce the need for additional hires and said the browser will track user activity to enable hyper‑personalized ads.
