description: The following analytic identifies the execution of qwinsta.exe executable in Windows Operating System.
|
|
This Windows executable file can display information about sessions on a remote desktop session host server. The information
|
|
includes servername, sessionname, username and many more. This tool is being abused of Qakbot malware
|
|
to gather information to the targeted or compromised host that will be send back to its Command and control server.
|
|
search: '| tstats `security_content_summariesonly` count min(_time) as firstTime max(_time) as lastTime from datamodel=Endpoint.Processes
|
|
where Processes.process_name = "qwinsta.exe" OR Processes.original_file_name = "qwinsta.exe"
|
|
by Processes.parent_process Processes.parent_process_name Processes.process_name Processes.process_id Processes.process_guid Processes.process Processes.user Processes.dest Processes.parent_process_id Processes.original_file_name
|

|
|
|`security_content_ctime(lastTime)`

|
| `windows_system_discovery_using_qwinsta_filter`'
|
|
how_to_implement: To successfully implement this search you need to be ingesting information
|
|
on process that include the name of the process responsible for the changes from
|
|
your endpoints into the `Endpoint` datamodel in the `Processes` node. In addition,
|
|
confirm the latest CIM App 4.20 or higher is installed and the latest TA for the
|
|
endpoint product.
|
|
known_false_positives: Administrator may execute this commandline tool for auditing purposes. Filter as needed.
