Detects the degradation of the system firewall security by the creation or re-enabling of per-application
exceptions via registry writes to the AuthorizedApplications\List keys under FirewallPolicy, which grants
the targeted executable network access and can be abused by malware to bypass network restrictions.

Detects a system shell interpreter being spawned directly by a Celery worker process.
This behavior indicates a Python background task execution framework is evaluating raw string input through a shell execution context,
which is highly indicative of successful command or prompt injection exploitation against an LLM agent task.

Detects alternate PowerShell hosts potentially bypassing detections looking for powershell.exe
Detects usage of "Reflection.Assembly" load functions to dynamically load assemblies in memory
Detects command line activity that tries to clear or disable any ETW trace log which could be a sign of logging evasion.
Detects suspicious powershell download cradle using nslookup. This cradle uses nslookup to extract payloads from DNS records
Detect adversaries enumerate sensitive files
Detects a process other than XBootMgr.exe spawned by XBootMgrSleep.exe.
XBootMgrSleep.exe is a Microsoft-signed Windows Performance Toolkit binary that can execute an arbitrary executable after a delay.

Detects obfuscated PowerShell scripts that enumerate Microsoft.PowerShell.Utility exported commands
and invoke cmdlets indirectly by array index. This can be used to evade detections
that look for explicit strings such as Invoke-RestMethod or Invoke-Expression.

Detects potentially highly relevant antivirus events in the application log based on known virus signature names and malware keywords.
