Ransomware program Spora can encrypt files without having to contact a command-and-control server. The malware has targeted Russian-speaking users so far, but its authors have also created an English version of their decryption portal. Spora’s creators have implemented a system that allows them to ask different ransoms for different types of victims. They also offer other services separately, such as “immunity,” which ensures that the malware will not infect a computer after infecting it or remove the program.”]
