Near the end of Hermione’s unveiling of her plans for the Goldstein and Ivanova memorial, there is a flash of light. The aurors assigned to guard Hermione manage to protect her from the curse.

His wand is aimed at her, and it is Hermione who manages to return his curse, even as an auror shields her body with his own.
