It can be described as a retrospective cyber case study.
Within the scope of this study, although there is no source or intelligence to start the research process, a search process for an undetected cyber event is carried out by scanning and threat hunting specifically for the assets in the corporate environment.
If a case is detected, the process continues with the determination of how deep the case goes and how wide it is.
At the end of the study, detailed reporting of the institution's exposure to an active cyber attack has been answered, but if there is a case in the past, the details are revealed.
