Firstly, I apologize in advance if this is not the proper forum to ask this question or if the question itself is too basic. However, I am conducting research and want to find hard statistics around the growth in prevalence of nation-state sponsored cyberattacks YoY. I am quite confident that they are increasing in frequency, however finding hard statistics of year-over-year growth in occurrences is proving very difficult. I have been able to find extensive lists of significant cyber events for each year, but it would require me to count hundreds of events manually for each year – was wondering if there is something more broad available. Once again, this must be specifically nation-state sponsored events, however whether the targets were public or private are not of concern.
