Ransomware has evolved since its origins in 1989 when the first known "AIDS" trojan spread via floppy disks. There are two main types - locker ransomware that denies access to devices, and crypto ransomware that encrypts files until ransom is paid. Notable examples like Cryptolocker and CryptoLocker have targeted home users, businesses, and public agencies on computers, servers, and mobile devices. Ransomware infects through malicious advertisements, spam emails, downloaders, botnets, and social engineering. Profits from ransomware have grown substantially, reaching over $18 million in 2015. Ransomware impacts many countries worldwide, with payments typically demanded through vouchers or bitcoins.
