Ransomware is a type of malware that infects your system, then locks or encrypts your most important data, allowing attackers to ask for a ransom. The attackers will offer to provide the decryption key only if you pay a certain amount of money within a short time.
IoT is one of the newest conduits for ransomware attacks. In the State of the Network Security 2021 report by Barracuda, 83% of respondents perceived the level of Operational Technology (OT)/Industrial Control Systems (ICS) cyber risk as either critical, high or moderate.
Ransomware attackers are increasingly employing more sophisticated attacks and defeating existing defences.
