A new cybersecurity threat targeting AI-assisted browsers has been identified by Brave researchers. Attackers can embed malicious instructions within innocuous screenshots or web pages, using invisible text that AI interprets as user commands. This exploit leverages optical character recognition (OCR) to process hidden instructions, enabling unauthorized actions like credential retrieval or navigation to sensitive sites without user consent.
Traditional web security measures, such as Same-Origin Policy and content-security-policy, overlook this vulnerability, allowing malicious commands to slip through unnoticed. To mitigate risks, organizations must enhance detection strategies to monitor AI actions and ensure the context of commands is secure. Recommended defenses include limiting AI features to trusted sessions, monitoring unusual assistant activities, and delaying the rollout of AI features until prompt-injection risks are addressed. As AI integration in browsers escalates, vigilance is crucial, treating every AI invocation as a potential high-risk action.
