+# API Reference: Detecting RDP Brute Force Attacks
+
+## Windows Security Event IDs
+
+| Event ID | Description | Key Fields |
+|----------|-------------|------------|
+| 4625 | Failed logon attempt | TargetUserName, IpAddress, SubStatus, LogonType |
+| 4624 | Successful logon | TargetUserName, IpAddress, LogonType |
+| 4776 | NTLM credential validation | TargetUserName, Workstation, Status |
+| 4771 | Kerberos pre-auth failed | TargetUserName, IpAddress, Status |
+
+## Logon Types for RDP
+
+| Type | Name | Context |
+|------|------|---------|
+| 3 | Network | RDP with NLA enabled (pre-auth) |
+| 10 | RemoteInteractive | RDP session after NLA |
+
+## Failure Sub-Status Codes
+
+| Sub-Status | Meaning |
+|------------|---------|
+| 0xC0000064 | User does not exist |
+| 0xC000006A | Wrong password |
+| 0xC0000234 | Account locked out |
+| 0xC0000072 | Account disabled |
+| 0xC0000193 | Account expired |
+| 0xC0000071 | Password expired |
+
+## python-evtx Library Usage
+
+```python
+import Evtx.Evtx as evtx
+
+with evtx.Evtx("Security.evtx") as log:
+    for record in log.records():
+        xml_str = record.xml()
+```
+
+Install: `pip install python-evtx lxml`
+
+## wevtutil Export Commands
+
+```bash
+# Export Security log to EVTX
+wevtutil epl Security C:\logs\security.evtx
+
+# Query failed RDP logons
+wevtutil qe Security /q:"*[System[(EventID=4625)] and EventData[Data[@Name='LogonType']='10']]" /f:text
+
+# Count recent failed logons
+wevtutil qe Security /q:"*[System[(EventID=4625)]]" /c:100 /rd:true /f:text
+```
+
+## Detection Thresholds
+
+| Pattern | Threshold | Indicator |
+|---------|-----------|-----------|
+| Brute force | >10 failures/IP in 15 min | Single-target credential guessing |
+| Password spray | >5 unique users/IP | Multi-user single-password attack |
+| Compromise | 4625 followed by 4624 from same IP | Successful brute force |
