On both the enterprise and consumer side, ransomware is a rapidly growing form of malware that effectively holds a user’s device or files at electronic gunpoint.
Ransomware infects a machine and renders it unusable until a ransom is paid to either unlock the computer or decrypt the data. Levels of attacks can vary and often it uses scare tactics, deadlines and intimidation to trick victims into paying up.
In recent months, most ransomware has been distributed via attachments in emails. Though ransomware threats can be advanced, its efficiency hinges on two factors: tricking people into clicking on malicious content and banking on them not having advanced threat protection.
The best defense against this increasingly popular cyber crime is a good offense. Operating systems, firmware, software and applications need to be patched and remain up-to-date to limit the vulnerabilities that are available for criminals to exploit.
In addition, organizations should prepare for the worst by backing-up systems regularly and investing in cyber insurance so that the business can make a full recovery in the event of a ransomware incident.
