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:Sysmon | EventCode=15 | DC0059 File Metadata |
| WinEventLog:Sysmon | EventCode=3, 22 | DC0082 Network Connection 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 |
|---|---|
ParentProcessName | Can be tuned to focus on common launcher processes like explorer.exe or winword.exe. |
DestinationIP | Filtered to exclude known good domains and internal IPs to reduce false positives. |
TimeWindow | Time between LNK execution and subsequent suspicious activity may vary based on adversary delay. |
FileExtension | Could be used to focus on .lnk files only or track associated dropped payloads like .dat, .exe, etc. |
