Money makes ransomware the lucrative cyber theft option. Crypto-Ransomware is a type of ransomware that encrypts files on a user’s machine making it unreadable for machine or the user. A decryption key is needed to unscramble the files thus making them legible again.
Dangers of Crypto-Ransomware
Crypto ransomwares are truly nasty. Once you are infected, there is no way out other than paying the ransom. At times, even if you have a back-up of your files and choose not to pay ransom this doesn’t mean the attack won’t cost you. CryptoWall ransomware, for example, leaves a strain of ransomware inside the machine. There are disinfecting costs as well as restoring data time which might take days. Some ransomwares like Petya, Goldeneye, Petrwrap have very advanced encryption algorithm which do not have any alternative then paying the ransom.
