<p>Detection focuses on monitoring registry modifications under HKLM\SOFTWARE\Microsoft\Netsh that indicate the addition of helper DLLs, followed by anomalous child process activity or module load behavior initiated by netsh.exe. These behaviors are rarely legitimate and may represent an adversary establishing persistence.</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 sourceChannelData component
WinEventLog:SecurityEventCode=4657DC0063 Windows Registry Key Modification
WinEventLog:SysmonEventCode=1DC0032 Process Creation
WinEventLog:SysmonEventCode=7DC0016 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.

FieldDescription
TimeWindowDefines the time window in which correlated registry and execution events are considered suspicious (e.g., within 10 minutes)
NetshChildProcessWhitelistList of expected or approved child processes spawned by netsh.exe in the enterprise environment
DLLLoadPathDirectory or filename heuristics to distinguish benign DLLs from malicious helper DLLs
