AN1633 Analytic 1633
Windows · attack.mitre.org · ATT&CK Enterprise v19.2
<p>Detects exploitation attempts targeting defensive security software or OS services. Defender observation includes abnormal process behavior (e.g., AV or EDR crashing unexpectedly), unsigned/untrusted modules loaded into defensive processes, or privilege escalation from security agent services. Multi-event correlation ties exploitation attempts to subsequent evasive behavior like service termination or missing logs.</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=7 | DC0016 Module Load |
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 |
|---|---|
DefensiveProcessList | List of defensive services/processes (e.g., AV, EDR) monitored in the environment. |
AllowedModulePaths | Whitelisted DLL/module paths normally loaded by defensive tools. |
CrashThreshold | Number of abnormal terminations of defensive processes tolerated before triggering an alert. |
