Hi Mops21,

This look like false positives.
Could you please make an archive containing these files and attach it with your next reply ?

Regards.

Hi Mops21,

No, the archive contained all the files we need.
However, it may take time until this is fixed. Please ignore these detections for the time being.

Regards.

The powershell script that calls rogue killer via my MSP gets killed by rogue killer. As a result code after the portion that runs roguekiller does not run.
The powershell script in the log will change with each run.

Thank you for your time.

Hi techknowledge,

Thanks for your feedback.
Could you please zip the detected powershell script and attach it with your next reply ?

Regards.

Unfortunately I will not be able to provide the script. However the script itself is not important in this situation. There are many scripts that I run through my MSP. They all run from that folder.

I fully understand not being able to white list a folder.
I was thinking more along the lines of providing a whitelist command line argument. If n argument already exists, could I get documentation on how to use it?

As it stands I have been forced to omit RougueKiller from my cleanup process.

Thank you again for your time, I do appreciate it.

Hi techknowledge,

There does not exist such a switch at the moment.
Maybe, you could share the script with sensitive information removed ? Which parameters are passed to Powershell binary along the script ?


Regards.

I understand now.
$args = @"
-scan "-reportformat txt -reportpath $ThisApplicationLogFile -portable-license $roguekillerlicense" -autodelete -no_interact
"@
Start-Process -FilePath $roguekillerexe -ArgumentList $args -Wait -RedirectStandardError $stdErrLog -NoNewWindow

Would it be change out -autodelete with something? I get the log sent every time it runs. If there is anything found in the log it goes direct to a tech rather than the general logging email address.

Could we create a follow up script that uses the log file to delete things previous found? That way we would avoid a second scan.

So indeed yes we detect when a powershell script is beeing executed.
However since it's a process only it won't be deleted, just stopped.

The easy fix for us would be to whitelist the file with a pattern, is that ok ?
Can you tell me what rule you file name follows ?
