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=10 | DC0035 Process Access |
| WinEventLog:Security | EventCode=4624, 4648 | DC0067 Logon Session Creation |
| WinEventLog:Sysmon | EventCode=13, 14 | DC0063 Windows Registry Key Modification |
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 |
|---|---|
AccessMask | Tunable based on what memory-level access the keylogger uses (e.g., 0x10 for read) |
ProcessNameExclusions | Legitimate accessibility tools may use similar API calls (e.g., Magnifier.exe) |
TimeWindow | Define how quickly access + registry mod + smart card use must co-occur |
