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 | open or read to browser cookie storage | DC0055 File Access |
| auditd:SYSCALL | ptrace syscall or access to /proc/*/mem | DC0035 Process Access |
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 |
|---|---|
CookieFilePatterns | Regex paths to known browser cookie locations |
TimeWindow | Correlated time range between cookie read and web upload or process injection |
BrowserProcPatterns | Expected names for browser processes being accessed |
