      <description>&lt;P&gt;Hi &lt;a href="https://live.paloaltonetworks.com/t5/user/viewprofilepage/user-id/182936"&gt;@akshayhariRajan&lt;/a&gt;&amp;nbsp;&lt;/P&gt;
&lt;P&gt;No, file hashes that you use to create IOC rules are not automatically blocked.&lt;/P&gt;
&lt;P&gt;To block file hashes you need to use the block lists:&amp;nbsp;&lt;A href="https://docs.paloaltonetworks.com/cortex/cortex-xdr/cortex-xdr-pro-admin/investigation-and-response/investigate-files/manage-file-execution.html" target="_blank"&gt;https://docs.paloaltonetworks.com/cortex/cortex-xdr/cortex-xdr-pro-admin/investigation-and-response/investigate-files/manage-file-execution.html&lt;/A&gt;&lt;/P&gt;</description>
