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:Sysmon | EventCode=2 | DC0061 File Modification |
| WinEventLog:Security | EventCode=4688 | DC0032 Process 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 |
|---|---|
TargetProcessList | Monitored browsers (e.g., chrome.exe, firefox.exe) |
AccessToolList | Suspicious tools used for injection or memory access (e.g., mimikatz, procdump) |
TargetCookiePaths | Locations of cookie stores like `AppData\Local\Google\Chrome\User Data\Default\Cookies` |
