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 |
|---|---|---|
| macos:unifiedlog | process: at, job runner | DC0064 Command Execution |
| fs:fsusage | file access to /usr/lib/cron/at and job execution path | DC0061 File Modification |
| macos:osquery | process_events | 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 |
|---|---|
AtPermissions | Whether `at.allow` and `at.deny` are properly configured. |
ExecutionCommand | Target binary executed via the at job. |
RunUser | Detection of root user scheduling job with unusual command. |
