Details
This is a generic password spray detection that can be used across all CIM compliant authentication sources.
Works based on a failure to success ratios common with malicious password guessing and can be run at longer durations to catch subtle password guessing attempts. (low/slow)
Sample data provided in splunk/attack_data#851 as an internal test case, but also works well against external facing authentication data sources (VPNs, webportals, etc)
