Grok Bot now detects hidden prompt injections, warns users and refuses to follow them

XFreeze · x · 2026-11-11

According to XFreeze on X, Grok Bot now surfaces a warning when a page or message tries to inject hidden text into your chat, and refuses to follow those instructions.

Example: ask about a store's return policy and if the page sneaks in commands aimed at agents, Grok Bot answers your actual question while flagging what it found. The poster frames it as a simple but important security habit built directly into the product.
