Seems like it affected several versions of the sensor (see the link I posted). There was no software update involved. It was in the channel file updates. I also don't admin Crowdstrike myself, so I don't know if that could have been prevented. 

 I'm not familiar with it either, just from what I read earlier. I now admin all RedHat Linux systems, with Oracle middleware running ERP systems and all of the infrastructure with those.
