Chapter 7 - The file and the chat authenticity

  • Excel, photo and video files are editable

  • What is hash code and image file and why they don't prove authenticity

  • A copy without the original source value nothing

  • What about the metadata?

  • No results of official digital analysis from NFS of the file

  • How the informant and Bang managed to detect the crimes?

  • Where is the database?

  • Lots of data is missing from the file

  • When is the last day of the chat?

  • Bang admits that the file is not capable evidence without the phone and without the original forensic file

​

Now let me explain in detail everything about the USB, the file and the chat. Why the file is so doubtful, and it can't be credible evidence. Why, all of its "protections" are all lies. Why it's not extracted by a forensic expert and how, most probably, this file was downloaded. 

The biggest problem of the USB that Bang received from the whistleblower and submitted to ACRC is that everything there is editable! The file that contains the chat is an EXCEL file. Everyone, even a child, could edit it! It doesn't need any special skills to open, type whatever you wish and give it "save". 

The other content of the USB are photos and videos that are also easy for manipulation, and they need a profound analysis to prove their authenticity. Of course for high quality editing/manipulation of the photos and videos one needs very special skills and experience, so I do not claim that they were really manipulated but just that it is possible. The existence of such option itself makes them not credible evidence. 

Taking in consideration that in the case was, obviously, involved media like SBS (+ TV Chosun and YTN) and all kind of experts in photoshop, video editing, etc. works there, everything is possible. Not to forget that in the case is involved a person who is an IT expert with all the skills and tools to create not just a simple photoshop but probably even high quality "deep fake" that only profound digital analysis could detect! I mean the guy from the forensic company, but I'll explain about him in the next chapter.

In the next chapter I'll also tell you how such manipulated by JTBC (another Korean TV channel) photo, was turned into key evidence that overthrew the former government and put in jail the ex-president and her aides. The manipulation that was so simple that doesn't need special skills and that was later easily proved to be false, but yet it was used in court as evidence! Just like in our case!
