<p>Unexpected modification of the KernelCallbackTable in a process’s PEB followed by invocation of modified callback functions (e.g., fnCOPYDATA) through Windows messages. Defender observes suspicious API call chains such as NtQueryInformationProcess → WriteProcessMemory → abnormal GUI callback execution, often correlating to anomalous process behavior such as network activity or code injection.</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=10 | DC0035 Process Access |
| WinEventLog:Sysmon | EventCode=1 | DC0032 Process Creation |
| etw:Microsoft-Windows-Kernel-Process | WriteProcessMemory: WriteProcessMemory targeting regions containing KernelCallbackTable addresses | 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 |
|---|---|
MonitoredProcesses | GUI applications (e.g., explorer.exe, notepad.exe) where KernelCallbackTable abuse is more likely. |
CallbackFunctions | Specific callback functions (e.g., fnCOPYDATA, fnDWORD) expected to remain stable. |
TimeWindow | Correlation interval between WriteProcessMemory calls and execution of modified callback functions. |
AccessMaskThresholds | Access rights values that should be flagged when targeting GUI processes. |
