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.
