The only sure way to protect yourself or your company from ‘ransomware’ is with foolproof file backups. These three backup options can all help recover from ransomware attacks.

You’ve likely heard all about “crypto ransomware,” or simply “ransomware,” a specific type of malware that attempts to hold your digital existence hostage by encrypting personal files and then offering decryption keys in exchange for payment. When the malware first takes root, it shows no outward signs that anything is wrong. Only after the malware does its nefarious work in the background are you presented with the ransom, typically via demands for Bitcoin or other forms of digital currency.
Some early ransomware was riddled with software bugs that made it possible to recover encrypted files that had been held hostage, but newer variants that use robust symmetric and asymmetric encryption are much more troublesome. (Symmetric encryption is typically used to rapidly scramble files, and the asymmetric encryption can then be applied to the original symmetric keys so data can only be recovered by cybercriminals with the appropriate private keys.)
