Log sources and channels
Exactly as MITRE states them in x_mitre_log_source_references. Where a channel is vague, it is vague in the source; kevmap does not tidy it.
| Log source | Channel | Data component |
|---|---|---|
| WinEventLog:Sysmon | EventCode=1 | DC0032 Process Creation |
| WinEventLog:PowerShell | EventCode=4103, 4104, 4105, 4106 | DC0064 Command Execution |
| WinEventLog:Sysmon | EventCode=7 | DC0016 Module Load |
| WinEventLog:Sysmon | EventCode=10 | DC0035 Process Access |
Mutable elements
Parameters MITRE marks as environment-specific. These are the knobs you are expected to tune; they are why an analytic is not a rule.
| Field | Description |
|---|---|
CommandLineRegex | Detects embedded PowerShell commands in SyncAppvPublishingServer.vbs invocation, e.g., `{powershell -nop -enc ...}` |
ScriptInterpreter | May vary between `wscript.exe`, `cscript.exe`, or called via `cmd.exe` |
PowerShellObfuscationScore | Used to detect encoding, obfuscation, or entropy level in embedded PowerShell payloads |
TimeWindow | Time delta between VBScript proxy invocation and PowerShell payload execution |
