Too Long; Didn't Read

When you combine cryptography with malware, you get a very dangerous mix of problems. This is a type of computer virus that goes by another name, “ransomware”. This type of virus is part of a field of study called “cryptovirology”. Through the use of techniques called phishing, a threat actor sends the ransomware file to an unknowing victim. If the file is opened it will execute the virus payload, which is malicious code. The ransomware runs the code that encrypts user data on the infected computer or host. The data are user files like documents, spreadsheets, photos, multimedia files and even confidential records. The ransomware targets your personal computer files and applies an encryption algorithm like RSA which makes the file unaccessible. The only way to access them is if the user pays a ransom to the threat actor by following instructions which appear encoded into the encrypted files. Thus it is called ransomware, because a form of payment is demanded in order to fix the problem.
