Some reviewers have questioned the claim stated in the Guccifer 2.0 NGP/VAN Metadata Analysis report that the .rar files analyzed in that study recorded file times in local (relative) time. In short, newer implementations of WinRAR use the “version 5” format and in that format times are recorded as UTC times. However, the .rar files analyzed in this study use the older version 4 format which records times in “local” (relative) format.
Some reviewers have asked about the use of “MB/s” as a measure of transfer speed. In the Guccifer 2.0 NGP/VAN Metadata Analysis report. “MB/s” refers to Mega Bytes per second where “Mega” is one million (1,000,000). Some reviewers have confused this notation with “Mb/s”, or mega bits per second often quoted by ISP’s. Those two measures of transfer can be confused with each other, and there are articles on the Internet that discuss this topic, for example here and here.
A study has been added which analyzes the file metadata in a 7zip archive file, 7dc58-ngp-van.7z, attributed to the Guccifer 2 persona. The analysis is here: Guccifer 2.0 NGP/VAN Metadata Analysis.
