Security researchers at NeuralTrust have identified a serious vulnerability in OpenAI’s Atlas browser, allowing attackers to deceive the system into executing harmful commands disguised as web addresses. This flaw stems from the browser’s omnibox, which processes user inputs without sufficient security checks. Attackers manipulate URL formats, creating strings that appear legitimate but contain intentional errors. When users paste these strings into the omnibox, Atlas incorrectly interprets them as trusted commands, bypassing safety features. The potential risks include redirects to phishing sites and execution of destructive commands, such as unauthorized file deletions from Google Drive. NeuralTrust recommends developers enhance URL parsing, treat omnibox inputs as untrusted by default, and implement user confirmation for cross-site actions to mitigate these risks. As agentic browsers face increasing security challenges, adopting these defensive measures is crucial to protect users from prompt injection attacks.
