Ransomware, a type of malicious software that infects and restricts access to a computer until a ransom is paid, remains a serious threat to business and individual networks and devices. It is frequently delivered through phishing emails and exploits unpatched vulnerabilities in software. The names of individual ransomware may vary (e.g., WannaCry, NotPetya, etc.), but NCCIC's best practices and guidance remain the same, including creating system back-ups, being wary of opening emails and attachments from unknown or unverified senders, and ensuring that systems are updated with the latest patches.
