Correlates the MiniJunk V2 persistence task with the execution of the renamed SoftwareLicencing.exe. This rule detects the creation of a scheduled task named "Synchronize OS" via schtasks.exe, and then correlates it with the execution of a file named "SoftwareLicencing.exe" on the same device. This behavior is indicative of the MiniJunk V2 malware used by the Screening Serpens APT group.

Detects the creation of scheduled tasks using `schtasks.exe` that include encoded PowerShell commands or base64 strings in their actions. This rule specifically looks for the use of `-EncodedCommand`, `-enc`, `-e`, `powershell`, `FromBase64String`, `IEX`, `Invoke-Expression`, and paths like `AppData`, `Temp`, or `ProgramData` within the command line, which are indicators of the PRISMEX implant used by APT28 for persistence.

This rule detects the creation or modification of a Windows scheduled task that includes 'deno' in its command line. This activity is suspicious as it can indicate malware establishing persistence on a system, especially on typical office PCs where Deno is not commonly used. Further investigation is recommended to determine if the activity is legitimate or malicious.
