Steganography (/ˌstɛɡəˈnɒɡrəfi/ (listen) STEG-ə- NOG-rə-fee) is the practice of concealing a message within another message or a physical object. In computing/electronic contexts, a computer file, message, image, or video is concealed within another file, message, image, or video. The word steganography comes from Greek steganographia, which combines the words steganós (στεγανός), meaning „covered or concealed”, and -graphia (γραφή) meaning „writing – Wikipedia

What you see is a proof of three government institution
documents hosted on the official servers.
Important aspects:
• Three different people
• Three different years
• The same institution (National Agency…)

If you haven’t noticed anything special in these images
it’s normal. During this analysis you’ll notice some details
that make the difference and will make you wonder
about some things.
These questions appear are covered on this analysis.

I can tell you for sure that I do not know what these documents represent or what their ultimate purpose is. 100% of these government documents have been modified by someone, a threat actor or a system.

However, their existence raises questions from a cyber security perspective.
For now, I can only imagine a few ways in which the documents have reached this state.
• The computer used to edit them is compromised.
• The software used is modified to insert those characters into documents.
• The server of the Government Institution is compromised and someone has made the necessary
changes.

If this seems random or of low severity …
think about what I mentioned earlier (server, computer, software) and the implications of each element’s personal and confidential data that may be compromised and exploited by cyber criminals.
