Windows · attack.mitre.org · ATT&CK Enterprise v19.2
<p>Monitor for suspicious use of Windows API calls such as IsDebuggerPresent() and NtQueryInformationProcess(), or processes manually checking the BeingDebugged flag in the Process Environment Block (PEB). Detect sequences of OutputDebugStringW() calls in short intervals that may indicate debugger flooding attempts.</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:Sysmon | EventCode=1 | DC0032 Process Creation |
| etw:Microsoft-Windows-Kernel-Process | NtQueryInformationProcess | DC0021 OS API Execution |
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 |
|---|---|
ApiCallFrequencyThreshold | Number of repeated debug-related API calls allowed before raising an alert |
ProcessAllowList | Legitimate debuggers or developer tools that may trigger similar behaviors |
