Rapidly escalating geopolitical tensions have increased concerns about the risk of cyber threats that can disrupt essential services with potential impacts to public safety. Most recently, public and private sector entities in Ukraine have suffered a series of malicious cyber incidents, including website defacement as well as reports of potentially destructive malware on their systems that could result in severe harm to critical functions. The identification of destructive malware is particularly alarming because similar malware has been deployed in the past (e.g., NotPetya and WannaCry ransomware) to cause significant, widespread damage or lack of availability of/to critical functions and critical cyber-dependent infrastructure.
Based on this heightened threat, please consider consulting some of the following links from CISA for controls and other best practices in cyber risk mitigation:
