<p>Detects registration of new or modified network provider DLLs via registry changes, anomalous file creation of DLLs in system directories, and suspicious process activity (mpnotify.exe interacting with non-standard DLLs). Multi-event correlation ties registry modification events to subsequent DLL loads during user logon activity.</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=4657 | DC0063 Windows Registry Key Modification |
| WinEventLog:Sysmon | EventCode=11 | DC0039 File Creation |
| WinEventLog:Sysmon | EventCode=10 | DC0035 Process Access |
| 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 |
|---|---|
MonitoredRegistryKeys | Specific registry keys to monitor for DLL registration (e.g., NetworkProvider Order). |
SuspiciousDLLPaths | Directories or file name patterns outside of normal system DLL locations. |
TimeWindow | Window correlating registry modification, DLL creation, and subsequent logon activity. |
