<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 sourceChannelData component
WinEventLog:SecurityEventCode=4672DC0088 Logon Session Metadata

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.

FieldDescription
TimeWindowCorrelate registry change and process execution within a specific user logon session (e.g., 5–10 minutes)
ParentProcessNameExpected parent processes for Active Setup launched binaries (e.g., explorer.exe). Deviations may indicate abuse.
StubPathValueEntropyDegree of randomness/uncommonness in StubPath values. High entropy may indicate obfuscation.
SignedBinaryStatusFlag if launched binary in StubPath is unsigned or uncommon for baseline
RegistryKeyOwnerCheck which user/context added the Active Setup key to detect privilege abuse
