Hi Piggie,

the powershell was spawned via WMI. You can try to check the WMI settings via autoruns https://docs.microsoft.com/en-us/sysinternals/downloads/autoruns.

The fileless malware means that the code for the powershell is on it's commandline. There isn't anything in the chest because there isn't any file to be stored there.

Regards,
PDI

Hi,

it's different type of the detection. The fileless malware may drop files during the execution and it's removed during a malware removal. If any file is deleted the detection is visible in the chest.
