Ransomware is a kind of malware that encrypts a victim's files and requires a ransom payment in order to decrypt them. There are several types of ransomware, each with their own special features and techniques of file encryption. The most typical types of ransomware are Cryptolocker, Locky, and CTB-Locker.

Once it infects a computer system, it will start to secure the victim's files utilizing AES-128 file encryption. The encrypted files will then have a.locked extension included to them. Cryptolocker will also display a ransom note on the victim's desktop, which will specify that the victim's files have been secured and that they require to pay a ransom of 1 Bitcoin in order to decrypt them.
Once it contaminates a computer, it will begin to encrypt the victim's files using RSA-2048 file encryption.

Once it contaminates a computer system, it will start to encrypt the victim's files using AES-256 encryption.
