Answer:
Reverse Phishing and Scareware
Step-by-step explanation:
Ransomware is a type of malware that denies access to data files using encryption until a ransom is paid. It comes under the category of cyber extortion. Ransomware does not intend to cause any damage to the computer’s file system instead, it displays a ransom note on the victim’s screen so that the victim can pay a certain amount of money to remove the restrictions and regain access to their computer, usually via a key. The malware creator will either supply a program that can decrypt the files, or will send an unlock code that decrypts the victim’s data. But there is no guarantee that this will happen, even if the requested ransom is paid.
Types of Ransomware
The two major types of ransomware are:
Crypto-Ransomware
Locker Ransomware
Types of Ransomware
Types of Ransomware
Crypto Ransomware:
Crypto ransomware aims to encrypt sensitive files on the victim’s computer. It does not block any basic computer function. This ransomware searches for important files on the local hard drive and external drives of the victim’s system and starts encrypting them. Then, it will present a ransom note to the victim, showing a countdown timer and asking for payment. The attackers generate income by holding the valuable files hostage and demanding a ransom through anonymous methods such as Bitcoin to regain access to these files.

Locker Ransomware:
Locker ransomware locks the victim out of their device and blocks basic computer functions. Some parts of the keyboard may be locked and the mouse can be frozen allowing the victim only to respond to the attacker’s demands. In this case, attackers demand ransom to unlock the device. The locked system only allows limited access, to interact with the attacker.
