Hi,

Good day!

Can you please tell me if we have a chance to check the application and websites which we have used in the recent time in the endpoint using the cortex XDR console?

Hi @DineshkumarA

Thank you for writing to Live Community. Regarding your query to check the application used in the recent time in endpoint, using XQL you can search for Process/application running and for website part you may check the dns query made by those associated process.

For reference please find below 2 XQL query's as example. In both query I have assumed endpoint name as "storm" for which we are gathering this details i.e. process name/application and corresponding domain name queried in the DNS request. If in case you would like to see only domain name for browser specific process then you may bolt your query with additional filter i.e. filter actor_process_image_name in {"chrome.exe","msedge.exe"}

dataset = xdr_data
| filter agent_hostname = "storm"
| fields agent_hostname, actor_process_image_name, dns_query_name, dns_resolutions, actor_effective_username
| filter dns_query_name != NULL

config case_sensitive = false
| preset = network_story
| filter agent_hostname = "storm"
| filter (dns_resolutions != null)
| fields agent_hostname, actor_process_image_name, dns_query_name , dns_query_type, dns_resolutions, actor_effective_username

Hope this helps!.

Please mark the response as "Accept as Solution" if it answers your query.

Thanks
