| Configured for Sysmon 10.2 | |
| Sysmon configuration plays a large part in the amount of events. | |
| I have configured the module to report back for a Sysmon hash configuration of: MD5,SHA1,SHA256. For any other configurations you will need to reconfigure the Propertybag array to report relevant algorythms. | |
| For simplicity I have also included a hashes field commented out. If included, it will show all calculated hashes in one line. | |
| When modifying $PropertyBag, remember to change the final Select-Object to ensure correct feilds are selected in order. | |
| For offline parsing of event logs modify script to remove "-LogName" and add "-Path <PATH_to_Logs>". | |

| Configured for Sysmon 10.2 | |
| Sysmon configuration plays a large part in the amount of events. | |
| I have configured the module to report back for a Sysmon hash configuration of: MD5,SHA1,SHA256. For any other configurations you will need to reconfigure the Propertybag array to report relevant algorythms. | |
| For simplicity I have also included a hashes field commented out. If included, it will show all calculated hashes in one line. | |
| When modifying $PropertyBag, remember to change the final Select-Object to ensure correct feilds are selected in order. | |
| For offline parsing of event logs modify script to remove "-LogName" and add "-Path <PATH_to_Logs>". | |
