Almost two months have passed since we first learned about the supply chain compromise of SolarWinds, and the community is still struggling to make sense of all of it. Enter MITRE ATT&CK. The speakers from the ATT&CK team will walk through how to use the framework to better organize what we know about the multitude of techniques from SolarWinds and related compromises. They will discuss both techniques that were previously known as well as those they recently added to ATT&CK in order to help attendees understand what actions they can take to better defend their networks.
