DET0553 Detection Strategy for Obfuscated Files or Information: Binary Padding

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=4688DC0032 Process Creation
WinEventLog:SecurityEventCode=4663, 4670, 4656DC0055 File Access
WinEventLog:SysmonEventCode=11DC0039 File Creation

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
FileSizeThresholdMBThreshold size in MB to determine suspicious padding
TimeWindowCorrelation time window between file creation and execution
UserContextScope the detection to suspicious or non-standard user accounts
