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 |
|---|---|---|
| auditd:SYSCALL | execve | DC0032 Process Creation |
| NSM:Flow | Outbound connection to mining pool port (3333, 4444, 5555) | DC0078 Network Traffic Flow |
| linux:cron | Scheduled execution of unknown or unusual script/binary | DC0001 Scheduled Job 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 |
|---|---|
CommandLine | The miner's execution path and options may vary by campaign. |
CPUThreshold | Environment-specific definition of anomalous CPU usage. |
