I have a zip file and want to know as much as possible about it. Some information is obvious like creation date etc. But what kind of information could be found by a forensic analysis?

    It is hard to tell what you are exactly expecting which makes this question too broad. But, take a look at the zip file format to get a feeling for the kind of information you might get when analyzing a ZIP file. Apr 1, 2017 at 7:41
  • What do you mean by 'forensic analysis'? The term is undefined. Are you asking what are all the ways to analyse a zip file to gain useful information?

  • Perhaps you could mention some specific information you would like to gain from the analysis?

  • I could retrieve some information about the source file system. It states NTFS. So the system packing the zip runs probably under Windows. But how to determin the packer?

You can use 'unzip' from fx. cygwin. unzip -l Archive.zip in a terminal/cmd.exe. While it will list dates of the files archive (CTIME and MTIME, perhaps) these are attributes that can be changed by anyone. The creation date of the zip-file is just the time at which it was downloaded/copied to your PC.
