The rise of AI-powered web browsers, including OpenAI's ChatGPT Atlas and Perplexity's Comet, is challenging traditional browsers like Google Chrome. These new tools promise to enhance user productivity by automating tasks, but they come with serious privacy risks. Cybersecurity experts warn that these AI agents require broad access to personal data, including emails and calendars, which can lead to vulnerabilities such as prompt injection attacks. These attacks can manipulate the AI's decision-making, potentially exposing sensitive user information or enabling malicious actions. While companies like OpenAI and Perplexity are implementing safeguards, experts emphasize that these measures may not fully protect users. As more consumers adopt these AI browsers, the associated security risks could escalate, prompting calls for better user education and protective measures.
