Last night, Russia invaded Ukraine. The foreign policy and political aspects of the situation will not be discussed.
What will be discussed:
In this day and age, a conventional war is never executed alone. There is likely a cyber war being waged in conjunction with the Russia/Ukraine conventional war. These cyber operations can be devastating. As an example, I recommend you investigate NotPetya attack in 2017. This was a Russian cyber operation against Ukraine that spread across the world, causing billions of dollars in damage to several multinational corporations and a host of others.
Currently, there are reports that Russia’s government websites are down. Although it is too early for attribution, it would be safe to say that a cyber war has begun playing out between the two nations. Much like NotPetya, it is reasonable to think that any cyber offensive operation by either Russia or Ukraine would spill out of the conflict and negatively affect technology operations across the globe, particularly in the United States due to its role on the world stage.
Patch your systems – most cyber threats of this type come from exploited vulnerabilities.
Stay up to date on cyber threat intelligence – nation-state actors tend to utilize previously unknown zero-day exploits. Keep track of the latest updates and subsequent patches.
Make sure your Incident Response function is prepared – perform a “function check,” walking through likely scenarios.
