In part 1 of this hunter’s den post we took a look at the adversary tactic of internal reconnaissance, including what kinds of artifacts might be left behind when internal reconnaissance has occurred on your network. In this post we’ll take a look at the types of data and the various hunting techniques that you can use to hunt for the various kinds of internal reconnaissance.
Datasets to explore
Data is a critical component of hunting, and many different kinds of datasets can be useful depending on the type of hunt that you are carrying out. For internal reconnaissance, there are two major data types that are useful to a hunt, process execution metadata and network connection metadata.
