Cybersecurity Threats and Responses
Gartner urges enterprises to block AI browsers
Computer World reports that Gartner analysts Dennis Xu, Evgeny Mirolyubov, and John Watts recommend blocking all AI browsers such as ChatGPT Atlas and Perplexity Comet because of “unmitigable cybersecurity risks,” including prompt‑injection attacks and loss of sensitive data to cloud‑based AI services. The advisory follows early‑stage adoption spikes, with 27.7 % of firms already hosting at least one user of Atlas.

New vulnerabilities expose AI browsers to credential theft
Researchers at Teamwin uncovered that ChatGPT Atlas stores OAuth tokens unencrypted on macOS, creating a pathway for unauthorized account access, while LayerX Security disclosed the “CometJacking” flaw in Perplexity’s Comet that could exfiltrate user data to attacker‑controlled servers. Both findings underscore the immaturity of AI‑browser security controls.
