Hunt a Living-off-the-Land Execution at Scale

No alert fired, but intelligence says an actor executes payloads via living-off-the-land binaries your rules don't cover. Your hypothesis: an Office app should never spawn a scripting host. You have millions of process-creation events aggregated by parent-child pair. Hunt the gap.

What you will be able to do

  • Name the scale technique that surfaces rare outliers without a signature.
  • Identify the long-tail suspicious execution and map its technique.
  • Close the loop into a detection and value a negative hunt.
