fix: Kerberos Manipulation - Update field to use Status instead of incorrect "FailureCode"
fix: Metasploit SMB Authentication - Remove unnecessary field
fix: Service Installation in Suspicious Folder - Update FP filter
update: Malicious PowerShell Commandlets - ProcessCreation - "Start-Dnscat2"
remove: Dnscat Execution - Deprecated in favour of an integration in the "Malicious PowerShell Cmdlet" type of rules
remove: SAM Dump to AppData
update: Critical Hive In Suspicious Location Access Bits Cleared - Enhance metadata and logic
update: Malicious PowerShell Commandlets - PoshModule - "Start-Dnscat2"
update: Malicious PowerShell Commandlets - ScriptBlock - "Start-Dnscat2"
update: Malicious PowerShell Scripts - FileCreation - Add "dnscat2.ps1"
update: Malicious PowerShell Scripts - PoshModule - Add "dnscat2.ps1"
update: Monitoring For Persistence Via BITS - Use "Image" and "OriginalFileName" fields instead of CLI only
update: New or Renamed User Account with '$' Character - Reduced level to "medium"
update: New Process Created Via Taskmgr.EXE - Added full paths to the filtered binaries to decrease false negatives
update: Potential Dropper Script Execution Via WScript/CScript - Re-wrote the logic by removing the paths "C:\Users" and "C:\ProgramData". As these are very common and will generate high FP rate. Instead switched the paths to a more robust list and extended the list of extension covered. Also reduced the level to "medium"
update: Potential Fake Instance Of Hxtsr.EXE Executed - Remove "C:" prefix from detection logic
update: Prefetch File Deleted - Update selection to remove 'C:' prefix
update: Sensitive File Access Via Volume Shadow Copy Backup - Made the rule more generic by updating the title and removing the IOC from conti. (will be added in a dedicated rule)
update: Shell Process Spawned by Java.EXE - Add "bash.exe"
update: Suspicious PowerShell Download - Powershell Script - Add "DownloadFileAsync" and "DownloadStringAsync" functions
update: Suspicious Processes Spawned by Java.EXE - Remove "bash.exe" as its doesn't fit the logic
update: Sysmon Application Crashed - Add 32bit version of sysmon binary
update: Tap Driver Installation - Security - Reduce level to "low"
update: Write Protect For Storage Disabled - Remove "storagedevicepolicies" as the string "storage" already covers it
