Editorial Analysis
Even patched, this class of prompt-injection attack signals that enterprises integrating LLM-powered assistants need continuous red-teaming, not just vendor patch reliance.
Inventory all Copilot and LLM-assistant integrations, confirm the patch is applied, and add prompt-injection scenarios to your next AI red-team exercise.
A patched but instructive Copilot exploit demonstrates that enterprise AI assistants introduce a new, testable attack surface requiring dedicated governance.
