Windows · attack.mitre.org · ATT&CK Enterprise v19.2
<p>An adversary running with SYSTEM-level privileges executes commands or accesses registry keys to dump the SAM hive or directly reads sensitive local files from the config directory. This behavior often involves sequential access to HKLM\SAM, HKLM\SYSTEM, and creation of .save or .dmp files, enabling offline hash extraction.</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=4688 | DC0032 Process Creation |
| WinEventLog:Sysmon | EventCode=13, 14 | DC0063 Windows Registry Key Modification |
| WinEventLog:Sysmon | EventCode=11 | DC0039 File Creation |
| WinEventLog:Sysmon | EventCode=2 | DC0061 File Modification |
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 |
|---|---|
CommandLinePattern | Detectable variations include `reg save`, `reg.exe save`, or PowerShell equivalents for dumping SAM/SYSTEM hives. |
TargetFilePath | Defenders can tune based on dump file path patterns (e.g., `%TEMP%\sam.save`, `C:\Users\Public\*.dmp`). |
RegistryPath | Tune for HKLM\SAM, HKLM\SYSTEM or access via direct \Device\Harddisk paths. |
TimeWindow | Temporal gap between SAM and SYSTEM hive dumping can be tuned (e.g., 3 minutes). |
ParentProcessName | Useful for suppressing known-good access (e.g., backup tools). |
