<p>Detection of anomalous RDP or remote service session activity where a logon session is hijacked rather than newly created. Indicators include mismatched user credentials vs. active session tokens, service session takeovers without corresponding successful logon events, or RDP shadowing activity without user consent.</p>

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:Security | EventCode=4624, 4648 | DC0067 Logon Session Creation |
| WinEventLog:Sysmon | EventCode=1 | DC0032 Process Creation |
| 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 |
|---|---|
ExpectedUserSessionMap | Mapping of users to hosts they are expected to access; deviations indicate possible hijacking. |
TimeWindow | Threshold for detecting rapid pivoting via hijacked sessions. |
