THE article discusses a newly discovered prompt injection attack, termed "Cryptographic Context Injection," which exploits AI assistants like Grok and Gemini. This attack involves hiding malicious instructions within encrypted data, tricking the AI into decrypting and executing those instructions as if they were legitimate. Researchers demonstrated that in Grok, simple commands could lead to unauthorized access to personal user data, while Gemini could bypass safety controls. To mitigate these risks, users are advised to be cautious with AI data handling, limit access permissions, and maintain updated security measures.
