The National Cybersecurity and Communications Integration Center (NCCIC) and US-CERT have issued an alert warning organizations to be vigilant of an increase in ransomware attacks across the world.
Ransomware is a type of malware used to encrypt data and lock users out of computer systems (or data) until a ransom is paid. Attackers typically try to spread ransomware via phishing emails or by downloading the malware to users after they visit infected websites.
Although not new, NCCIC’s guidance includes:
- create system back-ups
- be wary of opening emails and attachments from unknown or unverified senders
- ensure that systems are updated with the latest patches.
