Authors’ note:
A lot has happened in the last 5 days since Russia started its invasion of Ukraine on the 24th February 2022. In my bulletin I aim to conclude and share the information what I have gathered either through the support of the European Cyber Community or through my discussions with current and former members of armed forces in Europe. As my main profession – raising cyber resilience for organizations and nations to resist large scale cyber and hybrid incidents – requires me to holistically analyze the impact of multiple events happening parallel, I will not only focus on the cyber space aspect, but overall. For the strictly military movement timeline and events or ongoing fights there are many trustworthy resources out there, hence I will not put focus on that. This is not a study, I will not provide links and references. Many of the information you can simply search for, some or relying on personal discussions with subject matter experts.
Finally, everything written here is reflecting my own personal view.
