Security experts have raised alarms over potential vulnerabilities in OpenAI’s new AI-powered browser, ChatGPT Atlas.
Risks include prompt injection, data tracking, and memory-based behavior profiling.
OpenAI claims built-in safeguards but faces scrutiny from privacy advocates and cybersecurity professionals.
OpenAI's latest innovation, ChatGPT Atlas, has quickly taken the world by storm as the AI-integrated web service blends automation intelligence with real-time browsing. In an effort to create a more user-friendly and engaging web experience, Atlas will enable users to leverage ChatGPT’s features to navigate, search, and summarize data. October 21, 2025, marks the beginning of a new era of AI-assisted browsing.
The release is getting a lot of attention, making it one of the year's most talked-about tech releases. Cybersecurity professionals, however, have been warning against possible dangers. New Atlas functionalities, such as "prompt handling" and "browser memories," may enable more sophisticated attacks. The growing debate over its security risks versus innovation potential has been a driving force in the discussions around ChatGPT Atlas.
Soon after its release, security researchers began uncovering potential risks in ChatGPT Atlas. According to a Perplexity security report, several “significant vulnerabilities” appeared within just a day of testing. The following are notable threats.
The most concerning issue is prompt injection, in which hackers hide malicious commands within webpages or URLs. Since Atlas interprets text like natural language, these prompts can trick it into revealing data or performing unsafe actions. This makes AI-powered browsers more vulnerable than traditional ones, as they can be manipulated through ordinary content.
Atlas's browser memory captures web pages, user reading, and user behavior for personalization. However, it also poses the risk of profiling behavior and of misusing data if it is not adequately safeguarded. Privacy experts, including Proton, have cautioned that constant monitoring might make it difficult to distinguish between assistance and surveillance.
In AI agent mode, Atlas can perform automated tasks, such as submitting forms or visiting websites. If not monitored, these activities can contribute to phishing attacks or lead users to counterfeit websites, thus disclosing their personal data or passwords. Such automation has made browsers more vulnerable to attacks.
The multi-step automation from Atlas can be exploited to gather large amounts of data or distribute malicious links on a large scale. If the collective machine intelligence is compromised, automated tasks could cause harmful actions across multiple websites. Security experts also recommend limiting access to the activities necessary for the AI to perform. Risky operations should also be conducted in a sandbox or in an isolated manner to minimize threats.
OpenAI’s Chief Information Security Officer has acknowledged that prompt injection in ChatGPT Atlas remains a serious and ongoing threat. He stated that OpenAI has conducted “extensive red-teaming” and introduced new training techniques to reward the model for ignoring malicious instructions.
He further pointed out that the ultimate aim is to turn the AI agent into a trustworthy and reliable assistant. Stuckey still cautioned that prompt injection, even with the safeguards, “remains a frontier, unsolved security problem,” and the attackers would continue to look for ways to make it work for them.
OpenAI stated that the ChatGPT Atlas is designed with numerous safety layers to address increasing cybersecurity concerns, providing users with a safer, more transparent browsing experience while protecting them from AI-related risks.
Logged-Out Mode: Enables the AI to operate without accessing personal accounts or credentials, reducing exposure to attacks.
Scoped Permissions: Limits the logged-in mode to trusted sites and specific user actions to prevent misuse.
Memory Controls: Let users view, edit, or delete stored browsing data, ensuring transparency and privacy.
Prompt-Injection Protection: Detects and filters malicious embedded prompts in web content.
Continuous Security Updates: Regular audits and patches help fix vulnerabilities quickly.
With the launch of ChatGPT Atlas, the combination of artificial intelligence and everyday browsing has advanced significantly. While intelligent automation and real-time support are very convenient and accessible, they highlight a fine line separating innovation and insecurity in a more digitally evolving world.
As OpenAI continues to improve Atlas with new features and security fixes, the browser’s future will depend on user trust and robust security practices. Security measures such as logged-out mode and memory control are considered improvements over previous AI-integrated applications.
If effectively secured, Atlas could be a step towards responsible AI use, an area where intelligent technology helps people without compromising their privacy or security.
