From I Know What You Did Last Month: A New Artifact of Execution on macOS 10.13

Analysts that perform macOS forensics have had few, if any, artifacts of program execution to rely on during investigations — until now. In macOS 10.13 (High Sierra), Apple introduced CoreAnalytics, which is a system diagnostics mechanism that maintains a record of Mach-O programs that have executed on a system over approximately one month. CoreAnalytics can serve a number of valuable analytical purposes for both insider threat investigations and incident response. The artifact can be used to:

  • Determine the extent to which a system was in use, with accuracy up to one day
  • Determine which programs were run on a particular day, whether in the foreground or in the background
  • Determine how long, approximately, a program was running and/or active, as well as provide an approximate number of times the program was launched or brought to the foreground interactively

Howto disable CoreAnalytics permanently? Not just a cronjob deleting the output.
