Ransomware, or ransom malware locks users out of their device or just certain files which can only be decrypted in exchange for a ransom. Back in the 1980s when ransomware attacks were just beginning to appear, cybercriminals would accept payment by mail. However, today payments are made via cryptocurrencies like Bitcoin. In the early days of ransomware, cybercriminals mostly targeted individuals, but gradually shifted to targeting businesses small and large which offered a higher pay out. You don’t even need to be especially technologically talented to become a ransomware attacker now with the growth of ransomware-as-a-service (RaaS).
