Ransomware is any malicious software that infects computer systems or networks and operates by displaying messages that demand fees for the system to function normally again. It is a type of malware cyber-criminals use as a money-making scheme. Malicious cyber actors install ransomware through links sent via email or websites without the knowledge of the user. It has the capability of locking access to data through encryption, targeting sensitive files. Users can protect their information and data from ransomware by ensuring they have firewalls that block suspicious traffic. Also, security experts advise users to avoid visiting or opening unknown or suspicious links and websites. Having an updated antivirus also helps mitigate against ransomware.
