XQL to detect the ScreenConnect Client in response to CVE-2024-1709 and CVE-2024-1708

On February 19th ConnectWise released a security bulletin and update for their ScreenConnect software.  https://www.connectwise.com/company/trust/security-bulletins/connectwise-screenconnect-23.9.8
On February 20th ConnectWise announced that exploitation had been seen in the wild.  At least one proof of concept was available at 6:27 AM UTC Feb 21 https://twitter.com/watchtowrcyber/status/1760189490067390581 

The exploit complexity was incredibly low.  A demo can be found here https://www.youtube.com/watch?v=ud5FP-wHOcs

The following XQL will show hosts that have the Windows ScreenConnect client on them.  

config case_sensitive = true | preset = xdr_image_load | filter actor_process_image_name =  "ScreenConnect.WindowsClient.exe" | dedup agent_hostname
