<p>Multi-event correlation of Registry creation under Active Setup with anomalous execution of processes at user logon. Behavioral patterns include creation/modification of HKLM Active Setup keys with non-standard StubPath values, followed by process execution from uncommon paths, unsigned binaries, or unusual parent-child lineage post-user login.</p>

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:Security | EventCode=4672 | DC0088 Logon Session Metadata |
| WinEventLog:Security | EventCode=4688 | DC0032 Process Creation |
| WinEventLog:Sysmon | EventCode=13, 14 | DC0063 Windows Registry Key Modification |
| WinEventLog:Sysmon | EventCode=12 | DC0056 Windows Registry Key Creation |
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 |
|---|---|
TimeWindow | Correlate registry change and process execution within a specific user logon session (e.g., 5–10 minutes) |
ParentProcessName | Expected parent processes for Active Setup launched binaries (e.g., explorer.exe). Deviations may indicate abuse. |
StubPathValueEntropy | Degree of randomness/uncommonness in StubPath values. High entropy may indicate obfuscation. |
SignedBinaryStatus | Flag if launched binary in StubPath is unsigned or uncommon for baseline |
RegistryKeyOwner | Check which user/context added the Active Setup key to detect privilege abuse |
