As strange as this may sound, military attacks are no longer simply about soldiers and tanks and planes and bombs. Needless to say, there is nothing simple about war, but thanks to state sponsored hacking and the connected nature of critical infrastructure, cyber warfare has become a new front for every new military conflict. The conflict brewing in Ukraine is no different.
Threat levels have been raised by numerous national and international cybersecurity organizations, and malicious cyber activity is already being monitored related to this current conflict. Please remember that the types of attacks associated with these nation state conflicts are not perfectly crafted and restricted to only military targets. They can overflow into civilian networks that can quickly spread around the world in a matter of hours. NotPetya is a wonderful example of targeted cyber warfare run amuck.
Take the time to prepare your environments and make sure all your controls are in place and up to date. The Internet is staged to see quite a bit of malicious cyber activity in the days and weeks to come.
