OpenAI Acknowledges Ongoing Prompt Injection Risk in Atlas Browser
OpenAI has publicly recognized that prompt injection attacks remain a persistent threat to its Atlas AI browser. The company says the risk is unlikely to be fully eliminated and is investing in continuous defenses, including a reinforcement‑learning‑based automated attacker that simulates malicious inputs. OpenAI’s updates aim to detect and flag suspicious prompts, while it also advises users to limit agent autonomy and access. The UK National Cyber Security Centre echoed the concern, noting that prompt‑injection attacks may never be completely mitigated. Other AI firms such as Anthropic and Google are taking similar defensive approaches.
