This rule detects legitimate applications writing any type of file to uncommon or anomalous locations that are not typical for application data storage or execution. Adversaries may abuse legitimate applications (Living off the Land Binaries - LOLBins) to drop or download hostile files to uncommon locations on the system to evade detection by security solutions.
