What does the following output tell us?

 The output shows the top 10 hosts with the most malware in the last 30 days, based on the Cortex XDR data. The output is sorted by the number of incidents, with the host with the most incidents at the top. The output also shows the number of alerts, the number of endpoints, and the percentage of endpoints for each host. The output is generated by using the ACC (Application Command Center) feature of Cortex XDR, which provides a graphical representation of the network activity and threat landscape. The ACC allows you to view and analyze various widgets, such as the Top 10 hosts with the most malware, the Top 10 applications by bandwidth, the Top 10 threats by count, and more .
