Details

This PR has 2 detections aiming at LOLBAS usage from unusual locations or when renamed. Some false positives are expected based on testing in a production environment, however they are low enough to be easily filtered.

Updated LOLBAS File Path lookup (which was unused in other content) with current data from LOLBAS project. Also corrected a number of erroneous entries in the data to prevent excessive false positives. Added wildcard file path matching on lookup definition to enable detections above.

Pending splunk/attack_data#893
