The files parsed by this application may be found on any Windows system, if they exist, under [root]\ProgramData\Microsoft\Windows Defender\Scans\History\Service\DetectionHistory\[numbered folder]\[File GUID]
The file header should be of the form: b’0800000008′, or else it is not a valid DetectionHistory file.
Immediately following the file header and before the first mention of “Magic Version”, the GUID of the file is given in Big-Endian(?) representation, capped off by a b’24’ at the end, signaling the end of the GUID and beginning of the DetectionHistory data.
ThreatTrackingStartTime and all other timestamps are in FILETIME structure (UTC)
Most hex numbers in this file are stored with a swapped endianness.
