These artifacts come up in just about every windows compromise assessment, consider them core triage skills. There are several events, all of which I will go over in this episode. I will break them down from a DFIR point of view and give you the triage methodology...

This week I talk about career moves for the DFIR professional. The skill set is valuable, but it must be combined with the right additional technical skills to maximize future job opportunities. Of course, there is one skill set that stands out above the rest...
