<p>Detection of suspicious use of
tscon.exe or equivalent methods to hijack legitimate RDP sessions. Defenders can observe anomalies such as session reassignments without corresponding authentication, processes spawned in the context of hijacked sessions, or unusual RDP network traffic flows that deviate from expected baselines.</p>- Detects

- Part of
- DET0588 Detection of Remote Service Session Hijacking for RDP.
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 |
| WinEventLog:System | EventCode=7045 | DC0060 Service 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 |
|---|---|
ExpectedRDPHosts | Whitelist of systems and accounts authorized to use RDP; deviations indicate possible hijacking. |
TimeWindow | Time threshold for correlating logon events with session reassignment and process execution. |
SessionIDMapping | Environment-specific mapping of user accounts to session IDs; inconsistencies may reveal hijacking. |
