Windows · attack.mitre.org · ATT&CK Enterprise v19.2
<p>Correlates inbound network access to remote service ports (e.g., SMB/RPC 445/135, RDP 3389, WinRM 5985/5986) with near-time instability in the target service (crash, abnormal restart), suspicious child process creation under the service, and post-access lateral-movement behaviors. The chain indicates likely exploitation rather than normal administration.</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:System | EventCode=1000 | DC0038 Application Log Content |
| WinEventLog:Sysmon | EventCode=1 | DC0032 Process Creation |
| WinEventLog:Sysmon | EventCode=3, 22 | DC0082 Network Connection Creation |
| WinEventLog:Sysmon | EventCode=7 | DC0016 Module Load |
| WinEventLog:Sysmon | EventCode=10 | DC0035 Process Access |
| WinEventLog:Sysmon | EventCode=11 | DC0039 File Creation |
| NSM:Flow | Inbound connections to 445, 3389, 5985-5986 with high error/connection-reset rate, followed by new outbound sessions from the same host to internal assets within short interval. | DC0085 Network Traffic Content |
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 |
|---|---|
ServicePortSet | List of monitored service ports (default: 445,135,3389,5985,5986,1433,3306). |
TimeWindow | Correlation window between inbound access and crash/child-process (default: 10 minutes). |
AllowedAdminCIDRs | Known management networks to suppress benign admin traffic. |
MinConnErrorRate | Percent of failed/aborted connections to treat as anomalous (default: 30%). |
