00:00 - Introduction
01:00 - Going over the Unit42 Research that was posted to GitHub
02:30 - Downloading Chainsaw which is what we will use to parse the eventlog
03:20 - Running the hunt operation with chainsaw and default sigma rules to see some suspicious events quickly
05:45 - Using the search functionality to show us events with the process guid to show us what the suspicious file did
12:55 - Question 1: How many event ID 11's are there, counting each Event ID
